hi all ive just contacted HTC uk line and asked about the camera issues with the pink/red tint in the midldle of the pictures and it seems that HTC expect a fair amount of people to complain before they will look at it, the person i spoke to took a htc hd2 out and tested it and she stated she had the same issue but untill enough people ring and complain its a bust
so if u want the camera sorted then look here and call to complain
http://www.htc.com/europe/CA_Hotline.aspx
p.s. do u think the camera issue is software or hardware related
Is there a white balance manual adjustment anywhere? Haven't received my phone yet so can't check. I'm not talking about preset modes like "sunny", "couldy" and the likes, but somewhere where the colour temperature can be manually set? I'm a photographer btw
Edit: saw the other thread about it http://forum.xda-developers.com/showthread.php?t=584675&highlight=pictures with pictures! Could have something to do with metering modes cos this looks like it's getting the white balance wrong on some kind of spot or centre metering mode. Is there an "average" metering mode at all? Might be worth a try.
hi theirs no color temperature settings but their are three metering modes
-touch focus (spot)
-center area
-average
some tests of white/cream door:- autowhitebalance setting, super fine, everything else default, no flash
-------------spot----------------center area----------------average-------
some tests of stuff mag:- auto whitebalance setting, super fine, everything else default, no flash

if u have the time to change the settings depending on the lighting environment ur in, i.e. using the auto lighting setting gives red tints but with the indoor lighting settings its seems alot better dont u think, BUT its still visable
ouch, that white spot with the magenta halo thing is really bad. I'm kinda stumped on that one, especially as I can't have a play with it (and have no idea when I'll get mine!) I don't suppose you have an 18% neutral gray card lurking around you could take pictures of lol at least that'd give me a reference point. Sunny or cloudy settings might improve the overall appearance in daylight conditions rather than using the auto wb but it's never going to get rid of that much imbalance, even the left and right sides are different tones. While I'd never expect a picture from phone camera to be great, I'd certainly expect something better than that!

It is exactly what it says lol - a bit of card that's "officially" neutral grey - that's what we use to meter off to get the correct white balance in any lighting conditions.
A friend of mine should receive his phone before the end of the week, if he does I'll see if I can do some testing on the camera in daylight with a grey card and will let you know, of course
have you try to adjust white blance? Do not use auto model and choose something else. That may reduce the tint in the central area.

yep the indoor setting for indoor shots is much better so at least it's doing *something* nearly right lol - auto settings are rarely good anyway but they should manage better than that.
I personally think this can be fixed with a ROM because if you read the 4winmobile.com review and look at the pictures they took in the main review with a pre release ROM the pink spot is very noticable
Then scroll down to the updated pics taken with a Retail O2 ROM and the spot doesnt seem to be there.
I dont have a HD2 yet, but when I do and if its has the pink spot I will be ringing up, as I suggest anyone else who has it does too

I've got the English retail HD2 and there is NO tint.
All the pictures I've taken with my HD2 are great so far.
i have the english retail version too, please post ur device info, i.e. rom version and other info on the spec settings page
ROM version
1.43.405.1 (70124) WWE
ROM date
10/26/09
Radio version
2.04.50.22_2
Now I looked again and there is a bit of a tint but almost not noticeable, if you don't know about it. Might be an issue with all HDs but frankly, I don't care too much, because it takes great pictures nonetheless.
The folks from GSMARENA.COM have posted their full review of the HD2. it seems that they've encountered the same phenomenon as described here - pinkish color cast towards the center of the frame, especially noticeable when viewing the thumbnails.

Exactly the same here - ROM and results. Several test photos both of plain surfaces (wall/paper/sky) and general photos and there might be the *slightest* tint to one or two if you look at them funny. Certainly there's nothing even remotely like the disaster pics posted here and elsewhere, thankfully.
If it is a ROM issue, it seems this is a solid working ROM.
Hi all,
I reported this issue to HTC and sent them some sample photos. I received the following reply within several minutes:
Dear Mr Bale,
We are aware of this issue at HTC and are currently looking into it.
Apologies for any inconvienience caused.
Best Regards,

Colour tint issue
The halo of different colours would suggest chromatic abberation, which is hardware(lens) based so no fix possible.
Chromatic abberation normally shows up as fringing around contrasty edges (so could be anywhere in the picture depending on what you're shooting) not a massive magenta blob consistently in the middle of every single picture!
It's not C.A. you can notice this phenomenon with normal DSLR Cameras, which have exposed the sensor for long periods, and some parts of it being heated.
example - http://farm3.static.flickr.com/2560/3670598368_1cc6f5f72e.jpg
Checkout the upper left corner.
whether the sensor is defective, or its mounting process causes this - I expect HTC to handle this problem by replacing the affected units.
I have just recently started noticing that when trying to take a picture or a movie that on the "preview screen" there are lines that run vertically on the screen (in portrait view) or horizontal (while in landscape view) - they run from the top of the phone to the bottom.
I have looked very carefully at both the lens on the battery cover, and the lens on the actual camera (under the cover) they appear to be very clean.
I don't remember this being this way at all, and it wouldn't really bother me too much, but my pictures and movies seem to be affected by this. when i view a picture at first it looks ok, but when I zoom in further the lines are more apparent. (especially in the corners and top/bottom)
i attached a screenshot of the preview screen that kind of shows what I'm talking about (pay attention to the bottom and top of the picture to see the lines / distortion
* This seems to have happened within the last week. (older pictures don't have the lines on them)
* Haven't installed any new apps
* Running fresh 1.1
* Reboot doesn't help.
* Wifi and GPS off and still happens
Anyone else have this experience, or even better would be if someone fixed it.
-AndyS-
I have been running fresh 1.1 since it came out
I see what your talking about and from a photographic stand point. if it actually affects the photo when its taken and not just the preview I would say that there is something wrong with the sensor I would take it to sprint and have them check it out.
I have this same issue and it did not start until the MR release. Prior to that, the camera was pretty awesome.
I have been noticing this also and like the person above me stated... It didn't start until the MR release.
I have the same problem and I am also running Fresh 1.1. I started flashing right after I got it so I dont know if it was always like this. I have another Hero that has not been rooted, had the MR, and is taking great pictures. Tipharet and Doniiniicano, is your device rooted? and/or running a different ROM?? Sure a quick fix would be to bring it to Sprint, but I really dont want to deal with that.
if it was something to do with the MR then it is possible that they may have changed and or messed up the sensor settings.
BTW I am running Fresh 1.1 and have no problems.
This happens a lot in low light situations.. it did this on all my phones.. iphone, blackberry, Pre, Hero.. Cheap Sensors..
Im a photographer as well, and I can tell you there is a night and day difference in sensors in phones compared to regular cameras. I NEVER use my on phone Camera anymore.. because its so crappy.
night and day of course is different. However in low light situations I know for a fact that this did not start until the MR.
As far as the quality, for a phone it did not use to be that bad of a camera.

Yeah Im rooted, with fresh 1.1 but this happened before I even started flashing.
It's just high-ISO noise.
jonnythan is right. I did some research on camera noise and also found Banding noise. Banding noise is highly camera-dependent, and is noise which is introduced by the camera when it reads data from the digital sensor. Banding noise is most visible at high ISO speeds and in the shadows, or when an image has been excessively brightened. Banding noise can also increase for certain white balances, depending on camera model. So I guess if your Hero has this, it sounds like the only option is to have the device replaced and take a gamble the new one doesn't do it....or hope 2.1 fixes it <fingers crossed>

Ive never seem banding like that but hey its a possibility I guess it may be more noticeable on a camera like this than it is on a slr.
my phone was like this day one. I thought it was suppose to be like this since when I take pics I'm in low light.
Dont forget that we also only have 65K color screens. that will cause banding as well..

Here's an interesting article on the N1's display. Found it rather surprising!

yeah, eh... im not too worried about that. i think the N1 screen looks great and i never noticed any problems like that so i don t really mind
what a fake, if you look at that article with the nexus one, you can see the iphone photo perfectly
I would agree. Granted, they do show in those examples (if true) that the iPhone has the edge on number of colours, but I've not yet notices that, so I'm not going to worry

The photo of Mars sunset is a total red herring.
The issue is the gallery app, NOT the display.
Google Mars "sunset", open an image, and you'll see no banding. Save the image then view it in the gallery app, and the banding will suddenly appear.
yeah indeed
looks like the gallary is doing some kind of bad compression on the picture

I can't see much banding at all in the browser, this pic is the one I used for reference., certainly not what was shown on the Gizmodo site.
Saving it then viewing it in the gallery was a whole other kettle of fish, and THAT is what I'd equate to the image on Gizmodo.

I loaded the image in my browser on CM5 and there's a million bands. However, if you scroll around the picture, while you're scrolling it's beautiful. Only when the image isn't moving or zooming do the bands appear for me.
It looks like a bug more than anything else.
Okay, so I've just tried the one posted earlier in the thread, and yes there is banding, a lot of it, however if I touch the screen for a second it goes away and "drag" the screen down or up, then comes back when I remove my finger from the screen.
I still think this is software related, the image is so damn large that it must be being scaled down to be viewable, and maybe there's a compression issue there.

When I use the image from post #6, I see the banding. If I use this image:

Which is at 800x616 pixels, I don't see the banding. That tells me its the scaling algorithm in the OS, app or GL library thats causing the stepped gradient, not the AMOLED display itself.

this is more along the lines of what I was thinking. I thought maybe since the picture was being scaled down so much it was causing the banding. I love my N1 and the display is so nice that I can't even look at my G1 the same anymore.
Today,I was playing around with my Note, still worried about the black clipping and blocky videos changing ROM after ROM and didnt find any solution.
Out of curiosiry, I copied the GammaTest image to my PC, went to my display adapter settings, and cranked up the gamma from 1.0(default) to 1.5-1.9 and guess what?
http://imageupload.org/en/file/235342/gamma-normal.jpg.html
The first image shows the gammatest as it should. Here the computer's default gamma is set to 1
I increased my gamma value to 1.5-1.9 and this is the result.
http://www.imageupload.org/en/file/235344/gammahigh.jpg.html
And when setting the gamma to highier values, play all your test videos and images, there will be clipping and blocky pixellation just like you see on the Note. Try this for yourself on your PC.
This clearly shows that the clipping on the note is a software issue rather than a hardware defect and if we could somehow get to tune the gamma on the note, its the END of all the clipping and the horrible video playback.
A point to note is, when increasing gamma values, the images tend to become artificially bright and on reducing them, they tend to get darker. Maybe this explains why the Note produces the best whites as far as AMOLED displays are concerned and seems to be brighter than all the other Galaxy devices which includes, the Galaxy S, S2 and S3.
So the only and truly effective solution is to find a way to tune gamma values under the MDNIE settings and this should be implemented in a kernel. I've seen none so far which is capable of doing this. All CM9 based ROMS have Gamma control disabled under MDNIE settings. This also explains why the same problems were corrected on the Google Nexus with the LEAN Kernel.
This is definitely a GAMMA issue and definitely Software related.
I may be wrong, please do feel free to correct me if so.
Although I do agree (in my non-expert and in this regard completely worthless opinion) it is probably a software issue, this does not confirm whether our Notes' black crush is caused by software or hardware, or if it is fixable. This only means that you can make your display crappy by cranking up the gamma too high. The same result can be achieved in different ways.
I still dont understand the gamma test picture.. Which numbers should be seen? I see 4 to 21 perfectly and can barely see 3.. Should 2 and 3 be seen too?
Sry if I went off topic..
First of all, the image should be quite dark to see in a lit environment and on an ideally calibrated display, the image show a gradual fade to black. So theoritically speaking, on a good display, the left side is barely visible and is seen as a dark gray fading to black.
On the stock ICS kernels, the image is seen upto 4 and then clips to black. If you enable, Force GPU acceleration, you can see upto 1 which means more clipping. On stock GB, you can see all the way to 1. It varies from kernel to kernel.
We just need some way to access the gamma control under MDNIE settings on the Note which is at present, disabled on the CM9 kernel and is not present on any other kernels either.
When you wrote "CONFIRMED" i thought there was some quote from Samsung saying it was a software issue and they were looking into it
I had mailed GSMArena regarding this issue and even after they published it and many other blogs too, Samsung didnt give a damn about it. So I dont think they do now either. The EMMC Bug is more of a fatal issue and to date, even after announcing that they are "working" on a fix, there are none. People are literally bricking from the latest stock when all the other custom kernels have disabled the MMC_CAP_ERASE value from their kernels. So its better not to rely on Samsung for anything. They just sell their phones and thats it. The Note and everything alike are experimental phones and we are their lab rats. They basically only focus on the flagship Galaxy Phone. read GS3 and new ways to sell it.

Yeah because we have a unique display that is different from the I9100/I777 - so display tweaks for those won't work on N7000.

1) Seriously guys, we have to get to the root of this problem. If we can get to the gamma setting on this display we can solve the problem. But how hard can it be to get there?
2) On the other hand, i think that what you did, was change the gamma on an LCD display. As far as I know there are a lot of diferences between LCD and OLED, appart from the fact that we have a pentile display (2 subpixels per pixel, pixels are in RGBG formation) and the LCD uses 3 subpixels per pixel (RGB).
We should join our forces and start on a mission to solve this issue once and for all.

It is DEFINITELY a software issue. Try this out: reboot your phone, and while it is still booting and slowish, quickly start the calculator and see the top of the screen perfect and then, for no apparent reason, it gets some kind of a half-circle color spill. Also, when you open the gallery, find a folder with a stock video clip with jelly fish, and when you open that folder, gallery turns to black, and for a half of second it is perfect and then gets sort of color rendering problem. Final test is to start the camera when the night falls, switch to camcorder (for the smoothness), and just look at the screen, it is perfect, no black clipping, and then, as soon as you take the picture, the picture spoils and you get the black clipping- the live image on the screen while observing is totally normal. So, it is 100% SW issue!
I compared my Note to my friend's SIII and the screen is much darker on S3, and images themselves. So, it IS gamma issue. When you open the front camera on the SIII, in a bit darker environment, and look at yourself, you barely see the shape of your head, since gamma is much lower and it only picks up the bright parts, such as your forehead and cheeks. Also, images appear much MUCH darker on the s3 screen than what you see in reality. That is what samsung did to solve the issue: lowered the gamma.
Hope I gave some useful info (no pressure to hit the thanks button )
Cheers

ok, it is software. good. let's solve it !
It is not that easy..supercurio worked on it for 6 months and then left us hanging... He is not obliged, though..
We need a kernel which can access the gamma control. That is the only 'real' solution for this issue. You are right about the s3 having lower gamma and hence darker images. I've seen this myself and thats why I mentioned on my post that the Note's screen looks brighter due to the heavily cranked up gamma.
Apparently, this might be an issue with pentile amoled. Lower the gamma and lose pure whites for a clipping free darker image like on the Galaxy S or S3 or crank it up and get "richer" looking colours and whiter whites at the cost of extreme clipping in darker shadows.
This is the root of the cause. Improper gamma. Now only if someone who is experienced in developing Kernels would somehow enable gamma control which is present in the MDNIE settings but strangely disabled due to unknown reasons.
I saw that Liquid Black ROM has Gamma Control but didnt try that ROM yet. I really love the Tablet Mode in the Paranoid ROMS. So I want to stick to it while getting a solution.
I tend to agree with satish, it is then a hardware issue that could be remedied partly at cost other colours. I guess I was wrong, I use to think it was only caused by lower quality images, like watching tv on old crt, then watching same on hdtv, that also looks crap lol.

I wasn't comparing LCD and OLED. I just wanted to prove the point that it is indeed gamma which is set higher on the Note and it is not a hardware issue. I dont know why no kernel for the Note is able to access the gamma control settings. Maybe like Entropy said, the Note's display panel might be a unique design such that any tweak applied on the display may cause unwanted results. As you all know OLEDs have certain hidden characteristics and its more or less like DNA. Every OLED panel is different. So the manufacturer tunes it into the most optimum settings possible on the particular technology used in the panel. But here, Samsung just did it wrong.
If you have noticed, many custom ROMS offer scaling down the brightness even below the default Samsung values and thats when AMOLED's hidden weaknesses start showing up.
In the end, I feel the only solution to this is a Kernel which enables the Gamma Control or somehow enabling the Gamma Control in CM9 which is currently disabled in most CM9 based ROMS.

Not exactly a hardware "issue" but maybe more like a hardware "limitation" of "Pentile" AMOLED. Samsung has hidden this issue in the Original Galaxy S and in the Galaxy S3 by lowering the gamma which results in darker images but "NO" or "Invisible" clipping hence satisfying consumers. Due to the lower Gamma on those phones, darker shadows seem to blend into eachother hence we dont see any clipping as darks are "Dark". And hence, when consumers dont "see" any artefacts, banding or clipping on their videos and images, they are satisfied. But this is at the cost of "dull" whites or artificial whites and lower overall perceived brightness.
As the Note has its Gamma cranked up, White looks white. I may even go forward and say that the Note produces the best whites ever seen on any AMOLED panel. Hence web browsing looks richer, colours look richer and the overall perceived brightness is again higher than other devices, But this again comes at the cost of clipping in darker shadows and hence poor looking videos and images, blocky pixellation,etc
So in the end, everyone is ready to sacrifice their "whites" for a clipping free display. Thats how it works out for consumers. As long as they dont "see" the problem, they believe its not there. So this may be a limitation of "Pentile" AMOLED and lowering the gamma may be Samsung's way of hiding the weakness.
The Galaxy S2 has an overall best screen which I've seen and thats due to the RGB AMOLED Technology. Colours look richer, the percieved brightness is higher and no clipping either. Thereby best of both worlds.
gamma
1) I saw some minor fixes on this thread http://forum.xda-developers.com/showthread.php?t=1715416 but nothing really gets deep down to the problem. Those fixes are actually some kind of effects, they aren't so good. They talk there about some kernels that helps the black clipping issue.
2)I have found an apk that is called voodoo display filter, can you check it out? it does seem to enhance the black.
3)As i was playing around with the screen settings on cm9, i noticed that if i set the screen scenario to VT, the mode to MOVIE, and the outdoor mode to ON, i can see down to number 4 on the gamma test image (usually with the default settings i can see everything down to 1).

You are talking about the screen adjuster app which in my opinion is neither a fix nor a workaround for the problem. It destroys the blacks and uses the screen out of specification.
I have searched everywhere but couldnt find the apk for vodoo screen tuning. So, couldnt try that.
Anyways, this issue cannot be resolved with an app but only a kernel which supports gamma control.
You can find the app on bazaar android, i think it was made by super mario super curio, or something who used to work on this issue, and had a thread of over 50 pages, until he decided to quit the work because of flamers and stupid people.
I've had some ideas:
Can the devs add some new settings under cm9>settings>advanced>screen>mode ? ooooor instead of bumping the gamma on outdoor mode, to lower it?

Op please change thread title, as it is hardware.

Hi.
Since many of us have some difficult to take some good quality photos please share your experience with your phone. You can upload photos and wrote about which options you chosen.
I'll share mine when i have time...
Cheers.
The camera quality depends on the ROM also, i think
IMO, Aurora v4 has a good camera even if in the low-light condition, but the shutter speed is not faster than v5.
You can't be serious.
You can do better photos and videos videos with official 2.2 (Froyo) than with Aurora, and I'm not being sarcastic. Its the honest truth. Test it! I did!
For me this is a key point when chosing a rom as I often need to take photos and videos with some quality.
I rather have batery drains, low speed etc etc but have good quality photos and videos and Aurora is a complete disgrace in this field.
At the moment theres no better and stable than MIUI V4.
Good quality photo, specially outside that are just excellent and great 720p videos, without being blury, pixelized and without FREEZES!
If you want good quality cam, then MIUI V4 is the best choice so far this is not questionable.
Some might say the libs from MIUI are the same from Aurora etc etc. This is just Bla bla bla from people that didn't even tested nor compared both, because if they did they would see differences, Huge differences

No, exactly the same !!!
Tell me what's version of MIUI v4 you were mentioned !
my version of MIUI V4 PT 2.12.21
test it and put here the photos taken with the diferent roms
I want to see if they are exactly the same....
Did anyone change camera options? Specifically these ones: "Sharpness" and "Focus mode".
Off course.
But photos are just not vivid. Something is not right there

No, no need to test, the same !!
I also hope they are not the same, hope MIUI camera get better than Aurora, but ....:angel:
Ok keep the bicycle
Today I went to the park with the kids and took 2 backups with me, one for Aurora and one for Miui.
I have made a lot o photos with both roms testing lots of settings and 3 cam apps (native, cam360 and huawei cam).
Miui took beautiful and vivid photos while photos with Aurora where very clear look like the sun was immediately in front.
But one significant detail was, my son had a white hat and with Aurora the hat got a bluish tone looking like it's getting extreme white balance. If you understand about photos more white balancing the bluish the photo becomes.
Even reducing the white balancing the photos gets very dark.
Clear conclusion that is the libs are the same something is influencing a lot the quality of Aurora photos and it's a pleasure watch the outdoor photos and videos made with miui

But is not possible we can change libs from one to another and then MIUI options can port to Aurora? Still both of them should have same quality i think...

MIUI V4 PHOTOS
[URL=http://imageshack.us/photos/my-images/836/img20130427114138.jpg/]
Taken with the exact same specs.
Se the vivid and REAL colours of MIUI photos and see the extreme exposure + more dark colours of Aurora.
See the hat of the kid...
If you can't see the differences don't know what more can I do.
We can't contest true facts friend.
Now, I do believe that libs from MIUI are the same as Aurora but why the 8 to 80 difference?
Wow, love the kute baby
The exposure value seems to be changed by the light direction of your position. I'm not a photographer, just it's my experience.
Camera lib in aurora v5 seems to has some problem i thinks, it isn't good at the exposure capture (in auto mode), sometime it becomes crazy @@. And in this case, camera lib in Aurora v4 has done perfectly. I don't know dzo he has noticed about that or not, but i don't want to push him, he has alot work for other things. No big deal, it's enough for our phone.
And one more time, IMO, nothing difference bettwen Aurora vs MIUI v4 about camera libs.
O.M.G.......
Too much bright on Aurora photo you can see in park bench wood isn't brown. In MIUI photos have real color. Quality is same or both just some config on how camera holds contrast and brightness better on MIUI.
But MIUI v4 use libs from Aurora version 4 or 5?
not just the bench, see the baby hat is kinda blue tone....
these were photos taken with EXACT SAME SPECS with both rooms.
If you reduce brightness on Aurora than the Photos start to get very dark.
I have made all the possible combinations and just cant get the same output as MIUI.
So you can have na Idea, I have 2 batteries and I depleted both in aprox 2hours reboots, restire downlodas, vídeos, photos etc etc...
something is messing the photo output of Aurora and this what makes me completly crazy for not being able to use the rom.

Yes! The hat is some blue lines
I love to test MIUI but unfortunately i don't have my phone is in service. And i think your MIUI V4 doesn't work on my u8800 because of atmel has i previous tried.
Hope dzo read this thread and do something changes on his rom.
Just flash normal Miui v4, from Miui PT for example. That will work in your device.
Mine won't work because the changes I have made mess with atmel screens
This morning I printed the media_profiles.xlm file, located in
/system/etc of both roms and confirm many differences between them.
Then I restore a Aurora backup and replaced this file with Miui and rebooted.
Made no difference at all and photo still come out extra white making it bluish looking.
Tried to decrease the white balance by -1 point and increase the saturation but the photos are bad the same way.
I do notice one thing intriguing. I would like you to test it to.
You need to pay attention to this, In Aurora note than when execute the cam app, immediately it starts the image is great but suddenly changes to that extra white and bluish tone. This happens on starting the app and in a fraction of a second. You need to pay attention!
I'm 99% sure that some setting in the system gets affected resulting in this change, and here lies the issue.
This doesn't happen in Miui.
I honestly think this is it, and worth looking after it specially if something can be done to correct this behaviour.
If the system gets changed this way, something acts different between these roms, causing conflict without causing error on Aurora.
Imagine this situation, look like each Rom uses a different colour pallet and colour spectrum, obviously resulting in photos with different colour schemes. Understand what I mean!
This is it for sure!!
Can you guys check these situations and can the devs look to please. Aurora could be even better!

Hi,
I think Aurora v5 has the problem with the Exposure value (Iso:Auto and Scene Mode: Auto).
Did you check this in Aurora version 4 ?
Thanks for you post.
