Another Sony secret???? - Xperia Z1 General

We all know( or most of us know) that, Sony zx1's camera will stop functioning if we unlock bootloader before we update to Android 4.3. Sony has confirmed it, and fixed the bug in 4.3 update, and noticed this in their developer support site.We traced that it is due to the DRM keys being lost while updating TA partition while doing the unlock process.Similar case is also applicable for BRAVIA/X-Reality engine which will stop working after unlocking bootloader. But we wont notice that very much since we can live with out X-Reality or Bravia engine or so. But here is another big deal, especially for zx1 owners. ZX1 is sony's current flagship device with a much hiked camera/display/processor/build bla bla bla... Well telling about camera of ZX1, it is the highest mega-pixel one ever an android device have en-capsuled. 20.7Mp is big in papers. and additional hardware enhancements like G-lens, Exmor RS CMOS sensor (1/2.3-inch), BIONZ Image processor chip.. etc. Well everything related to camera seems good with lil WOW factor.
The question is will Sony still give us all these camera "POWER" if we unlock our bootloader??
There are rumours that the BIONZ image processor will stop functioning after ZX1's bootloader is unlocked. I came across this yesterday here on xda where i have put a thread on regaining X-Reality for unlocked bootloader xperia's(http://forum.xda-developers.com/showthread.php?t=2642608) with the help of DRM patching. And there, one of XDA member asked me about, regaining BIONZ functionality by patching DRM check. I was unaware of that till he asked so, all i thought was about that X-Reality issue and Music ID issue. Thus i happened to give it a check.
AND i was shocked with the result!!! WTF Sony screwed us again??
I had TA backup of my one week old XZ1, and have unlocked boot after updating to 4.3 (I thought i was one of the lucky guys who read a bit before screwing a nice piece of hardware.) and then i took single pic under low light condition ( becoz BIONZ and Exmor RS CMOS sensor is said to enhance pic quality in low light conditions according to Sony.) with superior auto mode and all other manual modes provided. Then i restored my TA backup ( Just that only , as i was using stock kernel, and i happened to unlock bootloader to just to get recovery and root on my stock C6903 14.2.A.1.136 firmware.) Then clicked pics exactly as what i did before, and then copied both sets to my computer to compare them.
Sony.... we will pardon you for not giving some software enhancements but not this one#*&^%$&^
As doubted earlier.. Sony have disabled some thing related to camera (BIONZ??) too for unlocked bootloader users!. This is not my conclusion, this is what those pics says.. Now i think this , it may be that piece of software crap ( just like X-Reality) which need a DRM key( Which is lost when unlocking bootloader) , makes the difference in image quality. As you can clearly see ( check my attached rar file) the low light processing is much better with a locked bootloader , though there is some purple tint in it.
OR... who know.. does the BIONZ processor will really work with an unlocked bootloader, or is it just the cpu which process the image instead of BIONZ for an unlocked device , like what that happens in normal sony phones which does not have BIONZ in them(this is a doubt provided by an XDA member on my topic about X-Reality).
Take a look at the attached file, all of them are taken under same lighting condition and phone is kept at same position.
While cross checking the images, all exif parameters for both unlocked and locked pictures are same for same picture modes, like shutter speed, iso, f, etc.. only the difference is in picture quality and sizes ....
XDA'ns we got another challenge from "DEVELOPER FRIENDLY SONY"!!!!
We will make it work soon.............. you SONY!!!!
Here is my dropbox link if somebody want to check the original picshttps://dl.dropboxusercontent.com/u/65718497/camera.rar

Thanks for the experiment and we found the problem now
I am no expert in android and i cant somehow help u
but maybe u can do experiment on android 4.2 becoz the camera is dead if bionz is dead
so u can do experiment if there's a way to make it working on unlock bootloader again
Maybe there's a way to modify the TA file of each of our phone, then reintroduce it again in unlock bootloader
So the bootloader is still unlocked, but all X reality bionz 5h1t works again?
Edit: I got what you mean wrong before lol

I cannot "clearly see" that low light procesing is better with lb than unlocked with that collage of yours.
Can you upload all the originals to flickr so we can better compare ?
I have to note the difference in fle sizes is minute, under 10% between lb & ub.

For so long people have wanted to disable BIONZ as they thought it over processed the images. You mean to tell me its as easy as unlocking the BL, post 4.3 ?
x-reality nobody cares about, because outside the phone not every screen runs it. I'd like images to appear how they would to everybody else.

DRM, X-Reality, BIONZ, etc...
All these are software.. and guess what ? proprietary software also...
They need to protect these softwares... unlocking the bootloader will open the doors wide open, so any hacker might be able to copy the DRM keys, and copy them to another devices.. or even trying to reverse engineer the DRM keys and find a way to decrypt the content...
Same goes for BIONZ, X-Reality...
That's why unlocking the bootloader will remove these functions to protect these proprietary softwares... and developers know this and respect this also.. some developers -open source developers- might have different opinion regarding this, but all share the basic idea is to protect their softwares.. no open source developer will be happy to see his work is being used without credit specially when the one who copied is actually making money from it...
Thanks god, we can actually backup TA partition, so when we re-lock the bootloader we can have every thing back like how it was before, other makers you can't do this, and some also the unlocking is irreversible... not to mention Samsung Knox which is the worst.. you can flash what ever you want, but if you did ( even a simple root ) the Knox bit will be changed and then warranty is void !! it's a one way process... regardless if the what you flashed is might actually make any harm to the phone or not...

29 pics collage reduced to the size of 9 MB !! you've got to be kidding me.
Whereas each pic in reality is 1.5-2MB.
You know what i can't tell much of a difference here at all.
Put them on flickr.

so if i used the drm key patch, bionz will still not work right?
i need to relock my bootloader

I'll do some tests with my Z1 and post full resolution pics

Dude thats not what i intended.. I rezied those pics to fit into a canvas. 8 mp shots are so large that u just cant match them side by side.. You can zoom in the bmp ( to fill ur screen) and compare pics side by side. Just check the colour changes.. And illumination. And if u r checking for precession details.. I must notice that, bionz is concentrated for low light enhancement and less grainy pics, than anything else. Any way i will uplaod a zip soon.

Dude can u check its perfomance in good lighted condition. If u can, then use a room with a constant light, and not an outdoor pic. As lighting variations can occour. Shoot the same object. With same camera position. Let us confirm what sony hides from us.

As @One Twelve said, please upload the pics to flickr, imageshack, dropbox.... somewhere that we can see the original files (also to see what's is going on with the ISO and shutter speeds.)
Bionz is a big "mystery" on the Z1, the Z does not have Bionz but the post processing (in automatic usually) is almost the same... The only thing I think bionz do in the Z1 when in automatic mode is try to get some noise reduction (SA tends to use higher ISO).
But nobody knows exactly what it does, and when it's working or not, will it work on 3th party apps? Some people says no, I did a compassion (kind of) between using the stock app and some 3th party app and I saw no big difference between the pics.

Finally!! Someone has noticed the Bionz thing... Till today after using the phone for 4months. I still see no effects of the Bionz, have been using FV5 app for night shots and irs way better then the stock camera. Perheps Bionz is just a gimmick thing?

Wasn't there a rumour that bionz wasn't activated or implemented fully in the Z1 yet? Sure feels that way, regardless, if it is or isn't, the pressure to keep the Z1 camera quality below its actual performance is probably due to the imaging department at Sony.

Bad pictures from camera

Hi.
I just received my Arc and I'm shocked by something : the camera does bad pictures, cause the codec is lame. A 8Mp photo take less than 1Mo.
Can someone fix that in a rom or a kernel or is this to hard to do ?
Thanks.
the photos from almost every other Arc are incredible.. I suspect you have a problem... maybe you're settings are wrong .. or there's a fault.
Look here for examples of how good it is.. http://forum.xda-developers.com/showthread.php?t=1035589
Look at one of mine (all are the sames).

By the way I'm using an LT15i (3.0.2.A.181) not rooted nor unlocked.
I've just rooted by arc. Is there a way to fix the jpeg compression ratio? It's way too high by default and images are losing details as a result.
Sent from my LT15i using XDA App
you can try vignette that barely compresses at all - but everyone is pretty much saying that the photo's from stock cam are still better!

Thanks mate. Yeah I noticed almost everyone's saying that...but if one was to put the facts together, picture size alone for a 8MP resolution image can't be less than 1MB...
Will try Vignette and see if it's better. I just hope there's some kind of tweak (like in the HTC HD2) where you could set the compression ratio to further improve the quality.
Sent from my LT15i using XDA App
You should try checking your camera setting OP.
Vignette is good, except it takes longer to preview the image in real size, and the unnecessarily 5~6x larger files with slightly worse quality than stock camera app.

What's settings are you talking about ?
What's the difference between the one's who have a good quality photos and the others ? The firmware ? They have a LT15a instead of a LT15i ?
Please help me to understand.
Did you use auto scene recognition? The picture has some heavy noise in it, so I suspect you play with exposure value or select night scene mode.
2nd picture is blurry; Did you hold your arc firmly when taking the picture ?
Yes I'm using the auto scene detection. Should I disable it ?
For the fisrt picture, the flash was activated.
And yes, I was holding it firmly.
I use auto scene detection for most of my photos and they seem much better quality than yours there. Try some outdoor shots and post them, indoor ones can have a lot of noise if the light is low anyway.
I once had similar problems with a nokia n95. Everyone was posting great shots and mine were horrible. Turns out the handset was faulty.

because the images u posted are processed and downsized in quality and size (~500KB).
the compression or noise reduction is visible in panorama not macro. the macros are food Also with 2.3.4

Less macro shots, more distant shots; let's see if detail can be resolved at a distance because macro makes it too easy. I am waiting for the official ICS to be out to show some side by side comparison against my other GB arc

Check my 1st link in post above. It seems at 100% zoom this images still seem compressed with smeared detail. The Sky has visible noise and smearing even in broad daylight. I'm getting the HTC One X when my cap is finished with the arc, I hope the photo quality is better than arc
I honestly don't expect the lack of detail or smearing to go away, I just think it's probably just a limitation of the camera; a minor improvement from ICS at best is optimistic. I tried lg camera pro, some minor arguable differences at 100% JPEG quality. It seems like the exmor R sensor has a flaw in daylight being unable to cope with brightness. I'd still like to see the oversaturation corrected at least, it's still present on the Xperia S picture samples I've seen.
Foliage looks terrible on the arc in bright lighting
http://www.allaboutsymbian.com/features/item/12866_Camera_champions_head_to_head.php
arc is good for macro shots and night shots, anything else shows its weaknesses
We have to wait for the new ICS kernel and drivers, I think the beta was built on the GB kernel so the camera output is unchanged.
As for image quality in the above posts, it's quite simple.
Small pixels = easy saturation = low dynamic range. In order to live up to the marketing bull of low light performance, all highlights are blown.
Small pixels = more noise. In order to live up to the marketing bull of backside illumination, extremelly aggressive noise reduction is applied.
So what could be a decent (though not exceptional) camera, it is now crippled by marketing decissions that the average consumer will never notice.
Since the average consumer will probably not upgrade to ICS, I hope that Sony will re-work the camera firmware in ICS and make proper use of the sensor.
I agree. The over saturation is its biggest problem, that and purple lens flare. Even stopping down the ev doesn't fix the saturation problem in sunlight.

I am even more troubled by the loss of detail due to noise reduction.
It is really frustrating to know that the detail was there but washed away. If only they could put a setting for noise reduction strength.
ICS official
i flashed my ard yesterday and one i know for sure, on GB pics weight 1-1.6MB and now 2-2.8MB
So jpeg compression level has changed for better, but still very strong denoising...
Xperia ray pics post ICS update
Can anybody post pics taken with xperia ray after ics update?
i have 2.3.4 and the pics are highly compressed. just want to see if that is removed in the update.

[HTC One vs Z1] Camera comparison test the shoutout

Z1 vs HTC one camera test / comparison - Vote please.​
@ Mods please move this thread in general if it doesn't belong here , ty !
ok so my cousins came at my place with 2 Z1's , we've taken them to test them out , it was cloudy day , as for flash light photos / indoor no flash photos z1 trully sux big time and they didn't want to let me have those photos , so all i have is daylight photos and 1 flash light and 1 indoor , don't ask how i got those 2 lol it was PAIN.
While taking pics z1 really has major issues with superior auto / white balance , while with manual it's slightly better but still not good enough imo due timing , they've took both pics with me average 3/4 pics each and average 2-3 mins took them for each pic with various settings at the end choosing the best outta 7/8 they took while i was snapping either 1 normal or some HDR pics that's about it. They've also deleted so many daylight photos where they were worse then me ... so not really an *FAIR* comparison due them being big time Sony fanboys and they're very stubborn and not accepting their camera isn't the best in the world lol.
Keep in mind i have no skills with camera tho my cousins know how camera works so they're more experienced then i am.
Anyway i'll let you judge the photos and i'll open a vote poll so vote for which you think it won overall.

I like the saturation in the Z1, but the HTC definitely capture more detail in low light with less noise. My conclusion is to use the HTC with a +.5 step in saturation.
In my opinin, and yes, I am a Z1 owner... seeing as you were using the Z1 in manual mode, you either had the ISO too low (50??) or you didn't adjust the EV accordingly as the Z1 pictures just look too dark really?
When in manual mode, you really need to take advantage of the settings

We've took photos @ around 10/11am lol , the saturation you like on z1 is cuz they had to use cloudy / daylight white balance due impossibility to come close to my pics , here few examples for you just so you see what I mean , anyway it wouldn't look realistic since there were no sun at all pretty much whole time. Only 2 pics had sun and that's it.
1st pic normal 2nd with daylight effect same as they used the whole time
I assume this is what you wanted ?
Keep in mind it was cloudy no sun at all , that why pics are less saturated on my phone but as you can see in the examples I could've done that but wouldn't represent realistic colors

I guess there is something to that mega pixel after all. Both cameras took good pictures and mostly comes down to settings. At least the Xperia don't suffer from the purple haze that many of us one owners has.

Exifs are there for all the pics
The Z1 user set white balance appropriately and actually used -EV compensation for a number of shots, might have over done it in some places. it's a difficult call. Auto isn't mature yet on the Z1, whereas the HTC one has been out for ages and from what i could tell the HTC camera took all the shots in auto. No tweaks.
The close up on the tree bark actually has the Z1 produce a blurred shot, dunno how that happened. Shutter was fast enough so no chance of camera shake.

ok so my cousins came at my place with 2 Z1's , we've taken them to test them out , it was cloudy day , as for flash light photos / indoor no flash photos z1 trully sux big time and they didn't want to let me have those photos , so all i have is daylight photos and 1 flash light and 1 indoor , don't ask how i got those 2 lol it was PAIN.
While taking pics z1 really has major issues with superior auto / white balance , while with manual it's slightly better but still not good enough imo due timing , they've took both pics with me average 3/4 pics each and average 2-3 mins took them for each pic with various settings at the end choosing the best outta 7/8 they took while i was snapping either 1 normal or some HDR pics that's about it.

What i'd like to understand better is this brightness value i see in the HTC exifs, it seems to change for each shot and wondered if any of the htc guys can tell me more about it. First thing you see is the HTC shots are all brighter, and in some cases more than necessary.
Questions to the OP
- how long have the Z1 owners had their phone and how long have you had yours.
- indicate which photo pairs are HDR (if any) ?
- Can you clarify whether the Z1 took the shots in 20MP or 8MP.
- Which program did you use to resize down to 1.4MP ?
- i don't understand what happened with the indoor shots. Saying they were really bad does not make sense to me. Without seeing the shots there is no way to comment.
- How about a low light shoot-out. I want to see shutter speeds of 0.3s on your htc and we'll see how that compares with the 0.8s on the Z1. Take care to stabilise the cameras so as not to have blur. If your cousins know what they're doing this should not be a problem for them

Actually this is fair, you should have done the same as this way it really is best that the cameras can do. These are pre-planned shots, you can take as much time as you want. There is no time deadline or any other constraints. When people put up their pics many times they put up the best of many. So this is normal.
Auto isn't mature on the Z1, it will take time. This means the skill of the Z1 owner needs to be better. The difference with ISO for instance can be signficant and not slight as you put it, auto can bump ISO up very high resulting in a noisy shot whereas you can get pretty good results if you set it manually. Your cousins did this already. Most reviewers do not.
This should not come as a surprise to an HTC owner, you have plenty of tweaks you can use as well. However, things like contrast, sharpness, saturation etc would not be fair as they're not present on the Z1 and can be done in post with better software. i note you did not use any of these 3 in any photos
great comparsion
for me htc one looks better , btw the photos is great
does your htc one camera sometimes show in screen regular noise while capturing photos? i want to know if this is a regular thing or only my unit does this .. another question , does your phone suffer from blue/red noise in dark or no ? i hope no:good:

In my opinin, and yes, I am a Z1 owner... seeing as you were using the Z1 in manual mode, you either had the ISO too low (50??) or you didn't adjust the EV accordingly as the Z1 pictures just look too dark really?
When in manual mode, you really need to take advantage of the settings

Hello there , I didn't even use z1 , I've wrote in OP that I was using my one and my 2 cousins were using 2 z1's taking each 3/4 pics each in total of 7/8 and later picking the best pic outta 7/8.
They look dark because HTC really has outstanding HDR while z1 really is no match with hdr.
From my observation with those difficult scenes z1 was useless , you could make pic but you would have to chose either sky/ clouds or ground , there's no option to take both like with HTC's hdr.
oh and believe my cousins were only using manual since superior auto was completely useless.
One Twelve confirmed this by checking Exifs.

The shots are brighter cuz of hdr , with z1 if you point at the sky for example bottom gets dark and it's clearly impossible for z1 to balance that due to poor hdr capabilities where's the htc one handles this easily.
My guess about brightness change is probably meetering and our auto / hdr can use higher values then what we can in manual.

Great post. It is nice to see almost a year in and our camera is still up there with its so called Ultra-pixels which is just a fancy word for mega-pixel. I never doubted this phones camera always served me well and even made a 2 hour long home movie to send back home.. Great phone but i think if sony put time and effort into their software they can get the camera up and running in brilliant quality too..

HDR takes multiple exposures and combines them. You have no control over this process. Given that auto isn't mature with Z1, it follows that neither will HDR be mature on Z1.
If you want good quality photos, then try not to use HDR. why ? jpg is lossy. jpg + jpg + jpg = even more lossy. Also takes longer as you have to wait for 'processing images' before taking next shot.
About sky/ground, what you do is use spot metering. If you spot on the clouds, the ground becomes dark, on the ground you blow out the sky, you have to spot somewhere in the middle. Now if the subjects are in the same focal plane then you can get away with this otherwise HDR is the only option as focus will not be at infinity. HDR is a compromise in this particular case to get you better exposed shot.
Its not required for every shot, only where there is big difference in lighting between foreground and background and subjects are in many planes that you want to keep more or less in focus. Personally, unless its landscape type photo this can be distracting, better to keep the subject in sharp focus and forget if the rest is blurred, it will make for a better shot.
In camera HDR is a recent 'innovation'. If you want the best HDR, then take 5 exposures from -2 to +2 with camera on a tripod, use a HDR speicialised program to combine them on a PC and then see the results compared to the 'poor man's HDR' the camera provides.

Then i would look only at the pics where HDR was not used in this comparison. HTC one has had many months to improve HDR, it did not come perfect out of the box. Same with Z1.

Z1 has been out now just under two months, takes time to get to know its quirks. Each phone camera is different. Since they set WB & EV i can tell they are not complete n00bs. But more hands on time is always better than less. Photographer is more important than camera.
Shan89 said:

If you have the originals, then look at the resolution. the 20MP will be (5248 x 3936) and the 8MP will be (3840 x 2160) or (3,264 x 2,448) . File sizes will also be bigger. I think they have used 20MP for all, can you confirm ?
This matters because currently you will get better shots with Z1 in 8MP 4:3 than with 20MP. Noise control is much better due to oversampling. Also 8MP means you can use different SCN modes which is not possible with 20MP. For low light shots or indoors this will make a difference.
For now we can say 20MP means 2x zoom is better than lower resolution sensors. Photos at 20MP are not necessarily better than 8MP. I wish these cameras put out RAW because then we will really see what the camera can do instead of what the compression program is doing to create those jpgs
When people make comments about camera they are primarily commenting about
1) auto and how well it works
2) image compression algorithm. good compression + good quality means more time + more CPU, a phone is not the best place to do this. So you can take the next shot quick, compromises are made here which affect image quality.
3) stock camera app. 3rd party apps in playstore may do a better job in certain situations.
So we still do not get to see what the camera can do without these other factors interfering in the process with ANY phone camera.

It was a good choice for image host because inspite of resizing it still preserved the exif data. Many others strip it out. I was surprised to see them. So you passed the minimum test here
Better still would be to resize them yourself with a good quality program and then upload. How well these image sites do resize is not transparent. They have to handle lots of load.

I'm trying to figure what you mean here. The only clue is flash is 2x more powerful. So in cases where a more powerful flash helps the Z1 could not compete but there are cases where your flash will be over powering and the Z1 will be just right. This isn't a problem because you can always diffuse the light by putting some paper on the flash. Where the more powerful flash has an edge is in freezing motion if subject is moving with low light, so long as it happens less than 6 feet away. But then flash makes for lousy photos since its direct at the subject and not reflected. Big problem with phone cameras currently. They always locate the flash below the lens instead of above it. I don't why this is. There is no off camera flash option available as yet. eg. you cannot bounce the flash of the ceiling and get better photos.
But why to use the flash in the first place, when both cameras can do good low light photos. None of the subjects in the photos were moving so there should not be a problem here.
We don't know what your cousins were thinking. Embarrassing does not say much, why was it embarrassing and what could be done to make it better. There are many indoors shots with Z1 in the photo thread, nothing embarrassing there.

This applies for impromptu shots. How often does this happen for you ? Not a single one of your sample shots comes in this category. My feeling is these impromptu shots are maybe 5% of the time. These are the hardest to get, subject may be moving and you will not get a good shot, you will get an ok to bad shot.
The rest of the time you can plan, take many shots, play with angles for better composition etc. But the thing about camera in your pocket is at least you have a camera in the first place and if the time is there you will get the shot whereas before you had nothing.
People say you are not supposed to get good photos because this is only a phone camera. But with more capable cameras they take lots of effort to get a good photo because its a good camera. Makes no sense. To get a good shot with phone camera you have to work harder because there are more limitations. This means more possibilities as well.

And what about 3 months from now ? will your statement still be valid.
if you follow the evolution of the Z, it took anywhere from 3-5 months after launch to get it right. So there is no reason it will change with Z1, maybe it might come sooner. This unfortunately is a sony thing. others will put out cameras that are mature but have bugs elsewhere. Nobody puts out a perfect phone at launch. Look hard enough and you will see the bugs, what matters is whether the vendor is prepared to fix them or not. How good is their past record in doing this.
But the reviewers always get the latest & greatest and then move on, they do not bother to review after 3 months. People also want latest & greatest and then find its not mature and think its bad. But after 3 months they change their mind. Just see the photo threads for any flagship here and you see the same comments. My <old phone> takes better photos than this <new phone>. very predictable :laugh:
if you look at HTC photo thread, around march-may, reviewers were complaining that htc is oversharpening images because they can see halos around the edges. What is the solution ? set sharpness to -2 or -1 gives a softer image and no halos. So htc got bashed quite a bit too. In fact i think htc is most bashed camera out there because everybody thinks 4MP is not enough. But what can they use to display 4MP ? there are no 4k displays out there or they are very expensive. Full HD is only 2MP. you can still print 10x14 inch prints with 4MP. But no... 4MP on HTC is not enough or bad. pfft.

This is one thing that still i'm not able to understand. 300 pg thread on this omg!. There are theories around but nothing conclusive as yet. Some people are saying the heat does it over time. With Z1 if it gets too hot you will not be able to use the camera. So too much heating over a long time is supposed to cause this problem with tinting. Its such a pity to replace the phone after only 6 months :crying:
This tinting is the problem as i see it with htc one. Not 4MP.
Too many peoples and companies think megapixels means quality, while using very poor sensors. They keep trying to push this rumor/agenda

@One Twelve
I'm sorry I can't bother answering to all questions etc , simply just take a look at photos and you got answer.
As for hdr stuff you wrote HTC one takes less then 0.5 Sec to make hdr photo and ready for next , I'm sure it takes over 20 sec to set z1 to make similar photo which is still no match.
As for fllash HTC one has smart flash = we.have 5 modes = it can fire up very low light or super strong light , this is why z1 will never match htc one in flash light photos , especially if photos are 1/2+ meters away , z1 is useless in this distance.
As for ceiling HTC one gets better flash photos when there are walls then when there aren't.
I can take photo outdoor pitch black about 5/7 meters away , indoor I can go up to 10 , if I increase exposure and lower contrast I can go even further.
HTC one also in long distance low light photos can take hdr + flash light = it gathers light from flash as well and makes overall picture more light.
With 4:3 HTC one also makes better photos then in 16:9 also sharper.
By the time z1 gets / if it gets fixed we will have updates as well + one 2 will be out by that time and more fair comparison would be one 2 due being newer 4/5 month's instead comparison vs HTC one which is 7 months older
As for Xperia Z I've took test with my cousins as well since they had XZ before z1 , I've literally raped Xz , I'll ask them to send me that test and upload it as well.
As for movement + picturing z1 will never match HTC ZOE.
here few samples for you so you see why :sly:
Btw all this pics were quiet tricky movement and impossible with burst shot or regular , but ZOE handles movement quiet easy.

If I am to judge, I'd say for the most part, the z1 does seem more pleasing. You seem to be abusing the hdr alot on the Htc one. The colors are washed out as hell. I can tell because I use the htc one as well.
I'll say this, neither the z1 nor the HTC One's hdr are good. Only the HTC One has a minor advantage.
If you are going to use HDR, set your ISO to 100, AF/AE lock on a bright light source AND THEN switch to HDR. This way your HDR will look much better than just using HDR right off the bat.
The first pic, I used HDR right off the bat. Looks washed out, basically it looks terrible
The second pic, I set ISO100, AE/AF lock on my ceiling light, switched to HDR. Much better colors.

Z1 isn't ready for a HDR shootout. It is ready for non-hdr manual shootout. When i have time i will select the non-hdr shots in your group and we will see the differences.

This bit is interesting. i don't think any other android camera can vary the intensity of flash light based upon what the camera sees. This is an advantage with indoor shots. Does not mean you cannot get acceptable ones in Z1 or any other that does not have this ability, its just harder. And once you know what to do its no longer harder.
So I'm not going with ease of use, i'm interested in whether its possible to take the shot or not. This is a better indication of limitations.

Useful but difficult to get right. People look more cold than warm. This is why the push to improve low light handling so there is little need to use flash in the first place. Flash photography on a mobile phone is difficult.

Surprising as i thought htc one has a native 16:9 sensor. Everybody else uses 4:3. So smaller pics come out better with 4:3 than 16:9.
So i'd have thought 16:9 is best aspect ratio for htc one.

Yeah, do that lets see the difference. Ensure the exifs are visible. After looking at the photo thread for Z, i changed my mind about what most people think about the Z. I would like to understand in which way the htc one 'rapes' the Z

I don't follow, with enough light you have a fast shutter speed so why is it hard to get those shots ?

I'm sad to say this but the z1 is the first and last sony device I bought. Why? Lack of development, locked bootloader and unable to unlock it. The fact it has a 21 mp sensor and I'm obligated to use 8 mp to take better photos than If took it with 21mp, video recording full HD only at 30 when the hardware can do 60 fps. And so on.
It's a shame. This device has a lot of potencial but it's wasted.

Because you get better images that way. Unlike older cameras that simply subsampled the image, the Z1 uses information from multiple pixels to reduce random noise. This is exactly what Nokia does with the 808 and some crappier Windows Phone models (1020, 1520).
With a high pixel count camera, you get very dense information. You most likely don't need such a dense information: you can print an 8MP image on A4 and still be over 300 dpi. When you look at the image on your screen, the PC/phone will blindly reduce the resolution to match your screen (which is 1920x1080, about 2 megapixels).
In other words, unless for specific corner cases, 20 megapixels is overkill. So, you're better off using that dense information to get a better, lower density image. The methods Nokia/Sony use for that are derived from seismic image processing, which is one of the cornerstones of the oil industry. Very complex, very well tested, and very accurate. For 99.99% of the pictures you take, they will be better than the raw 20MP image (and you do have the option to get the raw 20MP image when you shoot manual, although those corner cases are when a real camera would be the best choice).

Because you get better images that way. Unlike older cameras that simply subsampled the image, the Z1 uses information from multiple pixels to reduce random noise. This is exactly what Nokia does with the 808 and some crappier Windows Phone models (1020, 1520).
With a high pixel count camera, you get very dense information. You most likely don't need such a dense information: you can print an 8MP image on A4 and still be over 300 dpi. When you look at the image on your screen, the PC/phone will blindly reduce the resolution to match your screen (which is 1920x1080, about 2 megapixels).
In other words, unless for specific corner cases, 20 megapixels is overkill. So, you're better off using that dense information to get a better, lower density image. The methods Nokia/Sony use for that are derived from seismic image processing, which is one of the cornerstones of the oil industry. Very complex, very well tested, and very accurate. For 99.99% of the pictures you take, they will be better than the raw 20MP image (and you do have the option to get the raw 20MP image when you shoot manual, although those corner cases are when a real camera would be the best choice).

Thaks for information Then i used only 8 mpx for better quality
I don't know before how the pictures was token, now i can know how, and that good to say ! Thanks !
That hover looks good, is it a standalone mod? Or is pa a prerequisite? I'm thinking that this is my last Sony too. The fact that were tied to flash tool and using a computer is just a pain in the backside. Not to Menton the fact that my first z1 was unlockable. HTC and the one plus one for me. Maybe even the note 4.

locked bootloader photos vs unlocked (comparison)

To see the comparison , download the rar file from the sendspace link , extract the rar file and compare etc: before_superior1.jpg with after_superior1.jpg or before_manual2.jpg with after_manual2.jpg and so on....also hit thanks if i helped

there is def more noise after unlocking.. but not that much of a deal breaker in your examples.. it would be good if you had the chance to go for a more low light situation because it would probably be more apparent there.
but tbh, i cant decide yet which of those pics i like more. There is something more natural/defined about the "unlocked" pics compared to the smoothed out "locked" ones.

i didnt take photos with lower light because i dont think someone would take a smartphone to take pictures at night

Thanks, that helps me a lot!
It looks like the lost "drm-keys" for the cam is only for the software and makes only the pictures in digital use better and i think with GIMP i have better results if i want better pictures.
soooo i think its not realy worth it if you keep them/ custom rom calls for me

Nice thanks! I must say the difference in manual is minimal but with locked BL you have noise free image and slightly better colors and exposure. One thing to note is that in superior auto the after unlocked bootloader photos have lower ISO making for a bit bigger difference (First set 1250 vs 1600, second 640 vs 800 ISO, unlocked/locked).
