I have an Cingular 8525 and two of my buddies have another 8525 and a softbank X01HT. Why do my pictures suck in the dark and there's don't. They have the same good quality in the dark while my pictures come out very blurred and dark. I checked the adjustments and they were the same. Me and my friend both have the same rom on the 8525 and everything! I don't get it? Did HTC start shipping different lenses after time? Has anyone else noticed this?

My Tytn is not good in the dark. I doudt there is anychange in the lens but there may well be a difference in the auto light level increments. Before you ask how you could change that - I don't know. Don't even know if it's possible.

I dont believe that this is caused by lens. maybe version of Camera program is little bit different or some DLL file (but you said, it is the same). anyway you can compare it or try version from Trinity (it is here somewhere) but this version have not comfortable installation and do not support front camera and light I guess. But if your device is newer like the others, then maybe HTC used different (and perhaps cheaper) CMOS chip - I dont know, it is only speculation, but it is nothing unusually when electronic company uses cheaper components in newer pieces.
Ill try to get a picture so you guys can see the difference and what I mean. Adjusting the settings does nothing, in fact, it makes it worse for mine...

That would be interesting to see. It's not that we don't believe you, just that we don't think it's the lens that is different. My Tytn as I said above is very very poor at night but great for sunny day photos. I think in my older Tytn it is set too low for light exposure. It seems to adjust itself in incremental steps to the light level but in dark conditions it does not give nearly high enough a light exposure level. It is entirely possible in later/different models this hard coding has been adjusted for better results.

Ya, I just want you guys to see it. It's not a minor difference. Mine is so bad I don't even try to take photos at night, while my buddies' has unbelievable night photos...damn htc!

I feel your pain, I have this problem with mine (TyTN) too. It takes really bad pictures in dark areas, and most pictures look too dark and blurry even when there is a decent amount of light. I saw many cheaper phones doing a much better job. Really a shame.
My htc tytn also takes crappy night pictures. the front camera takes better ones at night. hell every other cell phone i had in the past and all of my friends phones take better night pictures.
very lame on htcs part.
is there a way to change how the camera detects light in video or still mode. the camera keeps adjusting to much during different contrast of the back ground that is being recorded
with a well lit area. i would like to sample the light of one area and lock its exposer time permanently.
Could it be software related? I mean, i've installed now Black Satin and i have the impression that the photoquality has gone down in the dark compared with the Black Dymond release. Or am i just imagining things?
I searched for a camera fix for the HD camera with no success. Does anyone know if there's going to be a fix in the near future? I'm sure that ya'll have the same problem that I do. Camera takes pictures that look old & rustic. Brownish tint to them & not very sharp for a 5 MP camera. I have adjusted all the settings for light & junk but nothing fixes it. As far as I'm concerned, it should take pictures IDENTICAL to a normal 5 MP digital camera. I can promise you that it's not doing that. Any help would be great, thanks in advance.

Why should it take pictures identical to a 5MP camera. The lens on the front is going to be vastly different, the sensor maybe 5MP, but what is the spacing on the sensor pixels? The closer together, the noisier the image. Colour balance will be down to the sensor too.
Regards
I'm not talking about the front camera. The normal camera on the back. I understand about the pixel thing, but it still shouldn't be so brownish, right? The pictures look like an old Polaroid picture. You know, the one's that spit the picture out as soon as you took it. Old, brown & nasty looking.
My pictures come out fine...
Hmmmmmmm...................... I'll just keep playing with it.

I'm not being flippant, but is it possible you might have a dirty lens?
Lol, that was the first thing I tried. Cleaned both sides of the back cover & cleaned the lens on the camera. Good idea, though.
The "5mp" doesn't really mean much, as stated earlier, if the sensor and lens are poor quality. As far as I know, HTC haven't released a phone with a reasonable quality camera, yet.
I bounce between different smart-phones (just coming back to WM now, after a year with S60). I can say that many of the S60 devices (in particular the Nokia N95, but also the N82 with Xenon flash) have very good cameras, being similar to low-end digital cameras in daylight. They lack optical zoom and tend to over-compress images, but have good quality lenses.
imho hd camera is excelent
pictures look old & rustic only if you make them inside house without using the artificial light setting, and this is also a general rule, not specific to HD.
Never seen a good phone camera yet, including the latest 8mpixel ones. They're all terrible.
Never
This camera will NEVER take pictures anywhere near what real cameras do. The photo sites are so tiny, they are smaller then the length of waive of light. Therefore noise, lack of dynamic width, etc. No patch will ever fix that. Sorry
open back cover , clean the lens , you will see a huge difference in quality

Not that I'm doubting you or anything but you do realize that the back cover only has a hole through to the lens?
You might try setting the brightness higher:
If you touch the small rectangle near the bottom right side of the screen (when holding landscape)
Then select the gear symbol, then select brightness from the menu and hit the "+" until it looks better that will remove most of the darkness.
The camera is a plain disappointment. In the time the camera autofocusses, I could have bought a Sony Ericsson C905's, create a good looking photo (with xenon flash) and upload it to imageshack.
If 'your object' makes the slightest move, your photo will be blurry . This is also the case when you attempt to make a photo of someone that isn't aware he or she has to be waiting for the autofocus lag. Head moves >>> blurry pic.
iPhone camera shots are way better quality, don't ask me why. Overall my Touch HD scores 8/10, where atleast 1 full point is taken up by the camera
and it's better don't speak about the very laggy video recording

Too many megapixels on a tiny sensor = major noise problem = blurring from denoise.
Even 2mpixels is too much for sensors this size, but people buy on marketing numbers of megapixels, not quality. You can just imagine the whining that would occur if the Touch HD came out with 1.3mpxiels, even though it would produce better pictures.

hehe, thats true.
mpixels dont count as much as the general public belives. the more mpix. the higher rezolution you can print the picture in. but for ordinary photos, 1.3 mpix would be enough, as long as the optics is good.
Personally, I rarely use a phone camera.
I use either my Olympus 720SW or Canon EOS.
the camera sucks **** compared to the n95 and the video recording is horrid. i know it's not meant to be as good as a dedicated camera but this is pretty bad given the price of the device.
i concur with mach03, move the camera a slight bit and eveyrthing gets blurred. one way i've semi gotten aorund this is to unlock the burst functiona nd take a sequence of pics and hope one or two coems out alright, not the most economic way to do it though...
i would ahve thought that maybe there's a way to tweak the camera to stop the blurring or even affect how much light is picked up by the lens which should also help with clarity

A silly idea, but seriously, did you check if maybe, just maybe, you left the "sepia" effect turned on???
just a small comparison between a professional camera and HD2's camera.What do you think? ( only cropped for same resolution, no color correction or anything)
HTC
EOS 400D

Apart from the awfully wrong white correction, the HD2 isn't shooting the worst pics outthere, it seems.
With much light the camera is good enough for snapshots.
I think the EOS400D body needs to be sent back to Cannon and have the sensor cleaned and calibrated. And the lens needs to be cleaned.
the pics with the HD2 seem warmer on the flower and china doll. But the pics of the building and sign, are not that good. The 400D looks a lot better (except the depth of field, were the HD2 is sharper).
I have been playing with my camera a bit, and I cant get rid of the pink spot. I installed the update, and it made it better. But I still have a very noticable pink halo around 90% of my pics.
Detail on the HD2 is good once resized to 800pix wide or so, perfectly good for web use but not much more. And yes, the color balance is very often completely off, usually skewed to magenta...
+1 on your EOS being faulty, shot one is ok but shot 2 looks problematic

i m not a pro photographer. how do you understand that my eos is faulty or un-calibrated? is it that bad? can you help me a little?what should i do?
The EOS is all good to me, just a couple tiny dust spots visible on photo 3, but nothing else...
The colors can seem "wrong" next to the HD2's ones... but it's the HD2 being wrong
I cant see anything wrong with your eos tbh. The eos out does the hd2 in every picture except i think the last one. The difference I can barely notice. The first picture especially you can see how the eos brings out the purple in the center of the flower. It is crisp and has a more vibrant colour. Also the hd2 white on the flower is not very clear.
However we are talking a pro camera and a phone and I think for snap shots my hd2 is the best phone camera i have ever had. Especially in the dark in a pub etc as that flash is blinding!! If i wanna take landscapes i'll crack out the T90 or the fuji finepix.
EDIT After looking again at the last picture i think i prefer the hd2's. I can see what kilrah means about magenta as the blues in the hd2 version of the last image is slightly more vibrant. If you look at the sign on the building in the background ( the long thin one with the white writing) i think the blue is nicer than that of the eos. Thats not to say that the eos hasn't actually captured the correct colour but the hd2 colour is nicer.
I'm all for HD2 pictures, but let's be honest here, you should learn how to take better pictures with the 400D. In capable hands, there's no way you can compete a DSLR vs a puny smartphone with a static lens.
totally uneven comparison
I own both, and of course in "tailored" shots you can notice only what appear to be bare differences (Except the horrible pink staining effect which is visible everywhere even if background colours may tend to cover for it), yet in "daily life" shots you cannot actually make much out of it... also remember HD2 has a complete unalterable assembly, while much of the eos 400d power comes from the lens that you mount on it, and I am not really comfortable at all to compare my 18-200 OS sigma lens to the plastic on the HD2
If I need to shoot items I want to sell online, I always do it with my HD2, or even if I need to get quick shots of things where the main thing is to "get the idea", but I would never fathom to use the HD2 in a real shooting situation... like when I'm on vacation. I would simply lose every pleasure in shooting if I had to do it with a phone camera.

i didnt try to take good or stylish pictures.only took daily shots in a hurry, no manual settings or photoshop corrections.other way of course canon will shot much better pics. but i wanted to show that hd2 is also pretty good
Except photos 1 (flower) all pics from the HD2 are better than from Eos, more crispy-sharp, more depth, more details
... but this is only my personal sunbjective impression, I´m no prof. photographer though

you're missing the pink that stains everything in the center of the viewport
Also, if I had to define detail, I'd say hd2 shots, when zoomed in, show a very, very "washed out" aspect all over the area, while zooming in all the way shots by the 400d you can only see the normal amount of moiree
its an interesting comparison, maybe we should leave it there as it doesn't really mean anything beyond showing the HD2 pics arent too bad at all - which we already new
I have the hobby of photography.
All pictures from canon are a lot better than htc, and it's normal.
The canon sensor it A LOT bigger than a phone sensor.
You can notice that the canon pics are sharper, have a better exposure, a better white balance, a smoother out of focus, are less grainy. In some you have the impression that are crispier, but it's due to oversharpening (and if you like would be easy to obtain in pp on the canon shots)
About the depth of field, due to the smaller sensor of the htc (the smaller the sensor the deeper the depth of field), in most shots everything is in focus. But in photography this is a flaw. If, for example, I shot a portrait, I would prefer to have the face in focus, and all the rest out of focus.
On the other hand, on a reflex, you can choose the depth of field you prefer opening or closing the diaphragm
There are new sensor on the way and I'm sure that in future quality of our phones will be more and more similar to quality of point and shot cameras,
but will never reach the quality of reflex for the lack of BIG, HEAVY, good lenses.
Stop criticising the guys photographic skills with his EOS. All he was trying to do is compare an image from the HD2, with an image from a dedication digital camera, to show that the HD2 isn't all that bad. And people jump in expecting him to take photographs like Edward Weston. Give the man a break!
On topic: Nice comparison. Good to see that compared with a proper digital camera, the HD2 is still pretty good.
can you share your camera settings in hd2?
brightnes
iso
white balance
image properity
flicker adj.
thank you
HD2 has a bit of a magenta cast.
On the other hand, this shows how good the HD2 camera is.
HTC has come a long way from the 1Mb and 2Mb shooters that came with the BlueAngel and Prophet. HD2's photos now gets compared to that of an SLR.
Buy a decent camera, and also buy a decent PDA/smartphone. End of story.
There are so many *freakin* experts here.

thanks dude you understand me
Besides my Turbo I also have a company provided IPhone5s so I decided to do a real world side by side comparison. Here is the setting: my truck is parked about 250' away from stop sign, I held each phone with both hands resting on the steering wheel. Both phones have all settings on AUTO the crossroad has a speed limit of 50 mph and no stoplights nearby so I am fairly certain the vehicles crossing in front of me are doing no less than 50 mph. My purpose is to catch the vehicles as close to the center of intersection as I possibly can, I took the Turbo pictures first and made every possible effort to capture the best picture possible with both phones. Observation: the shutter SOUND on the Iphone was instant, shutter SOUND on Turbo had an estimated full second delay. Look at the pictures and draw your own conclusions.

The Turbo has what looks like a simulated gray shutter closing when you take picture, when that happened the picture was captured, the sound followed the visual cue.

I have read here and other places what a dreadful camera the Turbo has, specially the inability to focus on moving objects and how slow it was to capture an image. I didn't want to dismiss the many stated comments about how awful the camera is. I also did not want to just simply say how I feel about the camera, to me it's a great camera for a phone. I did a heads up comparison between a camera praised often for being superior to the Turbo's and the Turbo camera consistently focused clearly on a fast moving object, the IPhone failed to catch a single vehicle in the focal area. I don't expect to sway the one's that hate the camera one bit, I simply presented evidence, proof of what the Turbo camera CAN do; not an opinion. WE all like here to look at pictures to prove a point... I gave you pictures.

Steve I did my best to present visual evidence and leave my own personal opinion out as best I could, I didn't know what the outcome would be and I would have presented results even if the Turbo had crapped out. I wanted to address focus and shutter speed on moving objects. The following IS an opinion: the camera is only as good as the hands holding it, even the world's best camera can take a bad picture in the wrong hands. The pictures the IPhone took were considerably darker than actual surroundings, the sky was NOT the darker blue in the picture and of course the obvious: no vehicles are present in the IPhone pictures, if you look hard enough to the right in one picture you will see the car I was trying to capture.
If you have a ceiling fan in your house or office, do the same test on the fan, well lit, low speed.
I've been doing that with the DT and whatever other phones I can lay hands on, none of them that
are built into a phone do very well. My observations that given some light and distance, the DT can
do OK with movement, but lack of light and/or up close action it's lacking. It isn't an accident that they
are putting dual flashes and ring flashes and such on cameras, the $2 sensor and lack of lens is really hurting.

You realize its the same camera that the Z3 has, right?
For a phone camera, it is pretty good. As for the ceiling fan, that is a rather silly test considering typical shots a phone will take arent that fast. Everyone can agree that there are a few aoftware quips that need to be fixed, but lets stop moving goal posts when someone defies a complaint, yeah? It's never going to be as fast as a DSLR or even a point and shoot.
I don't care if it's Genghis Khan's own Point-N-Shoot, it's deficient in a number of areas.
Like anything moving that isn't 20 yards away or in direct sunlight, or a christmas tree.
Nor am I alone. And that fake DSLR soft focus BS isn't fooling me either.
When conditions are favorable to the DT's camera strengths, it takes very nice photos, better
than my S4 for example, the rub is the S4 took better photos most of the time because it's
range of acceptable conditions was wider. There are a hoard of people with kids and dogs
which are frequently in motion that are not pleased with the basically useless camera in those
situations.

the grass is always greener.. if you read through some of those post you will come to the one where the guy with the Note 4 says he has similar results with what everyone praises as the one of the best cameras.. My DT could take some crappy shots as well as some amazing ones, and so can my wife's iPhone 5s.. I agree with an earlier comment.. I would say the overwhelming factor in getting good pics from any phone... is the user..
I now have the N6 and the story is the same.. some pics are trash some are great.., i take pics with that knowledge therefore I don't get as disappointed as I used to.

I think that the camera operator has much to do with the quality of pictures that come of the camera phone itself. This applies to non-phone cameras too.
Hi Everyone,
Have a look at attached example image to see what I mean.
Please try to take a manual shot with your wide lens in a very dark environment with very high ISO (3200 in example) and exposure time of 5secs plus (20 secs in example).
Everyone who has tried that so far has the same issue, a big purple shadow on the top. It's most likely the laser and it won't happen with the normal lense.
Do you have the same result? Any suggestions what we can do about it?
Whoa! I haven't seen that in a long time. I think maybe around the time of the Nikon D80. I can't currently try this out personally but by the sounds of it what has happened is called Amp Glow. It's when you kind of start getting out of the bounds of what is really acceptable shooting conditions for a given sensor. In this case, if you really are shooting in conditions that call for high ISO AND still need a shutter speed of 20 seconds and the image still comes out that dark, then you're way beyond realistic expectations for shooting with a cellphone. In the older DSLRs, people would see it when doing star trail photos that were 10 minutes or longer. Frame stacking software became the solution to this problem by taking a lot of shorter photos and stacking them up and pulling through the new dots of light. (And this is still used by a lot of photographers as it also gets rid of other forms of noise.)
So what is happening? ISO is pretty much the gain. It's the amplification being applied to the signal coming off of the sensor. Ideally with ANY camera, you want to stay as close to the base ISO of a given sensor. That's usually the lowest ISO number. (There are some exceptions where some camera manufacturers have done some trickery to get a lower ISO to show up but that was short lived as it didn't really help things.) Unfortunately, image sensors are not hanging in space. They're packed in with a ton of other stuff. Stuff that gets warm. If that stuff is near an edge of the sensor, that heat bleeds into the sensor and then those warmed pixels get amplified by the higher ISO and next thing you know, Amp Glow. Well, that's the simplified version at least.
A cellphone, any cellphone, is not designed for those kinds of shots. If they were, they would have a tripod mount, a much better flash, and a much larger sensor. (Yeah, the flash on your cellphone is not meant to light up stuff much past 5 feet. Even the ones built into a DSLR aren't meant for much past about 15-20 feet.) The reality is that cellphones are designed for handheld shots with decent light. Even the larger sensor used in some cellphones shouldn't be expected to pull any miracles that top end DSLRs are just barely pulling off cleanly. For that shot, you would want to use a dedicated camera locked down on a tripod using base ISO and long exposure at the very least. Although, personally, I'd probably just take a pass on that shot.
someone on reddit has the exam same issue with the wide angle. and someone said it's in the regular too. weird. my s7 never had this purple hue when I did even 30 second exposure at night.

something obstructing the lens maybe, or just camera went bad
Better hope this isn't the same problem the HTC one m7 had with the purple haze. The culprit was a light sensor on the camera would overhear and give a purple haze on the screen in low light. Place the phone face down and with the camera on and see if the purple comes back.

No, it won't happen with the same ISO/Shutter settings I took the previously attached photo. But maybe that's because it's not dark enough. Did the M7 issue only happen in dark enviornment as well?

Whoa! I haven't seen that in a long time. I think maybe around the time of the Nikon D80. I can't currently try this out personally but by the sounds of it what has happened is called Amp Glow. It's when you kind of start getting out of the bounds of what is really acceptable shooting conditions for a given sensor. In this case, if you really are shooting in conditions that call for high ISO AND still need a shutter speed of 20 seconds and the image still comes out that dark, then you're way beyond realistic expectations for shooting with a cellphone. In the older DSLRs, people would see it when doing star trail photos that were 10 minutes or longer. Frame stacking software became the solution to this problem by taking a lot of shorter photos and stacking them up and pulling through the new dots of light. (And this is still used by a lot of photographers as it also gets rid of other forms of noise.)
So what is happening? ISO is pretty much the gain. It's the amplification being applied to the signal coming off of the sensor. Ideally with ANY camera, you want to stay as close to the base ISO of a given sensor. That's usually the lowest ISO number. (There are some exceptions where some camera manufacturers have done some trickery to get a lower ISO to show up but that was short lived as it didn't really help things.)

Thanks a lot for the detailed explanation. My question here would be, why doesn't it happen to other phone-cameras with similar settings?

Yes the m7 only happened in low light / dark environment. Do a Google search for HTC one m7 purple haze. What caused me not to buy another htc phone

Settings aren't the only part of the equation. The other par is the placement of other components within the device. I need to look at the tear downs to see how the various parts are placed next to each other but something is heating up and passing that heat to the sensor. Just off the top of my head there are four parts together; the two camera sensors, the laser focus module, and the flask module. Each one of those on its own will generate heat if used enough.

It's the same issue. I haven't looked at the HTC issue but from your description of it, it's the same. Amp glow is what it is called in digital photography. (OK, silly that I said digital as you don't get amp glow in film.) The glow will show up because there is no other data coming off of the sensor for those pixels and the heat is amplified as "data".

Ok, just watched the JerryRigEverything repair tear down. The flash module sits right next to the wide angle and the laser focus next to the regular sensor. There is no mention as to what is sitting next to the sensors on the main board but I see silver boxes on each side with one having some sort of black and yellow warning sticker. Not sure what they are so I can't rope them in as culprits. So for now, I'd say it's a combo of the four units of the camera assembly.
Were you running the flash or one of the cameras a lot while you were playing around? Shooting a lot of long exposure shots in a row?
I'll get to test out some night shots and video tonight at a lighting ceremony but I'm still not expecting to shoot 3200 for 20 seconds type shots. Again, that's pretty extreme.
