I'm wanting to find out if the noise in some of the photos i've taken is normal for the HD2
I expect noise in a camera like this, it's just the nature of having such a small high mega pixel count sensor, I just wanted to find out if what im experiencing is normal. I've got a week left on my 14 days and would like to exchange it if it's not normal
This is probably the worst of them all that I did lastnight
http://twitpic.com/1cs2cl/full Look at the banding noise at the bottom of the frame.
http://twitpic.com/1cs4lj/full This one has some too, but not as bad as the other
http://twitpic.com/1cs50y/full This one looks like it may be a optics problem, look at the red halo around the sykes sign. the 1st time i took the pic i though maybe there was a smudge on the lens so i wiped it and still had the same result
Perfectly normal.
You're taking pictures at night and even standalone digital cameras would struggle to take a decent picture in those conditions.
The Camera will be ramping up the ISO which increases the noise anyway (and as you pointed out coupled to a small sensor just isnt great), the only way to take a decent picture with noise that isnt noticable is to use a tripod, a very small aperture and a very long shutter.
This, being a phone, doesn't have the luxury of that kind of control.
Just take pictures during the day and they are decent enough.
i get it too, including the exceptionally bright flash that usually washes out most photos, just have to live with it im afraid, or fiddle with camera settings, see what happens, but you'd have to constantly change them between night and day....
Thanks, Yeah i expected the noise in pics from the phone. Just the banding was concerning me a little bit.
It actually does pretty good at night in certain situations, there are more pics on my twitpic account from last night that came out ok, very little noise, though a bit more blur. im guessing it probably picked a lower ISO for those.

I have to agree, the camera on the HD2 is outstanding in the daylight, nearly rivals the Sony T33 that ive carried around for a long time for quick snapshots. I just wish they could put a small optical zoom on the camera, even something as small as the 3x optical zoom im used to the with T33. im sure that's asking a bit much with the space constraints within a phone. Im still happy none the less.
The camera in my old Wizard was worthless, i barely ever used it. It was passable outside on a bright day, useless under normal indoor lighting conditions or darker.
Found myself in several situations where i wanted to take a pic but didn't have the T33 on me. HD2 = problem solved =)
I just noticed that there is a TMO USA HD2 specific forum. Since this is about a TMO USA HD2 could one of the mods move this thread over there? Like to see what kind of response i get from other USA version users
ROM 2.10.531.1 (82076) WWE still has a huge pink spot in attached pictures. Looks like it's definitely a hardware problem with probably the low-quality plastic lens. Possible chromatic aberration?
yup, my phone has it too. I took some pics of a blank sheet of paper and there was a nice pink hue in the middle of the paper!
Wasn't there a software fix for this?

The released hotfix is only for 1.66 roms and LOWER, and assuming this 2.10.x rom has all previous hotfixes rolled into it.
I see.
For the record, I have the same ROM as you and I don't seem to have the spot.
Camera
I have taken probably 100 + photos and have yet to notice any spots.
In fact, so far, I am very pleased with the quality of the photos the HD2 produces. By far the best camera on any phone I have owned, and thats been quite a few...
Stock rom installed.

take a pic of a blank sheet of paper in daylight and see if any pink shows up, or anything that's white will do.

Just tried it, and no spots. Someone mentioned the lens cover, possibly a lens to lens problem. Others are not effected by this problem as well.

I'm having a problem with green tint in my pictures. And sometimes the flash makes the pictures too bright. There should be a way to disable one of the lights in the flash. You don't need it all the time in my opinon. I called tmobile about the green tint in my pics. They are sending me a new phone. Hopefully it works out ok. Has anyone else experienced this??
I'm not having this issue. I would have to say it's probably a manufacturer's error.
Have you contacted T-Mobile or HTC about it?
BTW, this phone's video and picture capabilities are actually better than my $200 Cannon, LOL!
i only get the greenish-yellow tint only when it's a picture taken with flash, lol, pick your poison, no flash for pink, flash for green-yellow!
yes i did...they are going to send me a another phone. Wish me luck
I still have it after manually patching the phone. I think it has to do with shooting outdoors in sunlight though.
I've checked my history of FUZE/Touch Pro pictures and they have a pink spot too (visible in the histogram in Picasa)!
It looks like it's common HTC camera problem that I can date back possibly to the TyTN II which explains why it still shows up in TMOUS HD2 after all the European HD2 hubbub. So much for Quietly Brilliant.
That's unfortunate for ANYONE who has experienced this "apparently" still existing issue with the camera. I have had NO such trouble, whatsoever. All of my photos have been insanely crisp, and absolutely gorgeous.
Then again, I did perform a registry tweak to increase the maximum resolution that the camera is capable of outputting.
now that you mention it
Heres some pictures i snapped all of which have a slight pinkish tint to them i didn't notice it till today. Anyone working on a fix? Or should i see if T-mobile will trade me out phones?
Normally i wouldn't care but I take a lot of pictures like all the time and this is gonna start bugging me
HHHMMMMM Interesting
Look what I found
http://pocketnow.com/thought/clarification-the-pink-spot-syndrome
let me go take a picture with my Nexus see if it does it too
Edit: Ok Im back and so i guess HTC FTL!!! lol j/k oh well i guess I'm gonna have to settle for pink.
I'm gonna try my Dads 3GS next time I see him.

So that's why I see it in my Touch Pro too! So it must be camera optics.
It can't be sensor/uv burn-in because TMOUS HD2 is brand new less a week old spending most of its time in indoors and in pouches. It's very apparent on histograms.
If it's a white balance issue, it is contradicted by the fact it's a circle and not an overall image issue. It's also NOT present on DSLRs and other normal cameras that I've used.
Hi, I don't know how various settings affect the results. However, I wish to be able to take excellent photos and videos under different conditions. Are there any good apps that take better photos and videos than the stock Camera App? I am using GB. Thanks

In photo 1, I do not know why the ceiling lights are like that.
I changed various settings but there was no improvement.
In some cases, the overall color of the room changed.
In photo 2, the room appeared to be dark but it was not.
I changed the flash to auto, on along with changing other
settings. The room still appeared to be dark.
In photo 3, again, that place was not dark. Setting the flash
to auto or on did not help.
In photo 4, everything including the room appears to be somewhat yellowish.
In reality, the wall is white and the pillows are gray.

Thanks for the suggestion but I am not a professional. I don't know how various settings affect the results. By the time I have tested out various settings, things that I want to capture will have been gone.
ah now things are getting clearer . your pictures looks a little bit like something is wrong with the 'white balance' of your camera. so you can try different settings for the white balance, the default should be automatic (AWB). I'm not an photoexpert too, but maybe some one else can guide you further with this.
Thanks for pointing this out. I also tried white balance but it did not help. Perhaps I did not do it properly. Hoping somebody could provide some tips. Are the strong glares from the ceiling lights in photo 1 also caused by the white balance?

This effect on the ceiling lights is due to a hardware fault, there are no settings within the phone that can correct this. You can try, like me, and use photoshop. For me, its no problem because I have used photoshop for many years, but others are not so fortunate. This fault is well documented. Samsung know about it, yet have done nothing to correct it. The only way is to send the unit back to the retailer for a new unit. I tried three or four brand new units and they were all the same.
In general. The camera has limitations because of its size and proximity to other circuitry that may introduce noise etc. Its 8megapix with a tiny lens, so as is, I feel it does a pretty good job (apart from that pink dot that is). To get better pictures, consider post processing with photoshop. If that's not an option, and quite frankly I would not recommend purchasing it just for pics from any camphone, try the GIMP, its free and does an awful lot to enhance your pics. You can find the GIMP here www.gimp.org it will run on linux, windows and the Mac
Hope that helps
So, getting something like Camera ZOOM FX won't help.

Good question. I know the S2 does, and we all know about the Galaxy Note. I can see evidence of the problem on a slashgear.com presentation, and its that presentation that stopped me from going over to the S3. However, there are plenty of youtube tests where it seems pretty good. The S3 has only just been released, so it might be a while more before any issues become apparent. I think its one where you try before you buy. Personally, I'm not touching either the S3 or the 'Note until I have proof that the issue has been resolved.
Edit. The fault is commonly known as "the pink dot"
In photo 1 was the lens clean? Might sound obvious but even the slightest bit of grease or diet can affect how sources of light spear in photos. Typically in any photo I take where I light bulb or something similar is in the picture if the lens was not completely clean I got a similar effect as in photo 1

Well, there must be a lot of pink dirt around. My crappy clam phone must have pink dirt repellent, because no matter how greasy the lens gets, pics from it don't have a pink dot. Neither does my DSLR when the uv filter gets filthy, or my specs come to that. Sorry, but the dirt bit on this issue is a red herring. The camera has a defect.
I use UCam. A lot of "pro" settings and also some cool. And... you can disable shutter sound.

i think you should send the device to service/repair, because i think this is an hardware issue. i saw a lot of pictures taken by the note (not only my own device) and they are al just fine with the standard settings.
I just noticed that there is a protective film covering the back camera. Probably Samsung put it there to protect the lens. Do you think this is the cause to all of my problems? Am I supposed to remove it? For the first few days after purchase (3 weeks ago), the Note took excellent photos. As for last week and the week before that, it depends. The thin protective film has been there right from the beginning. Let's say the protective film covering the lens caused the pink dot, how do you explain why the cafe in photos 2 and 3 appeared to be dark whereas in reality, it was not. Also, photo 4 looks yellowish overall.
Hi,
Protective film would most likely create the effect on pic one. (which would be visible when a direct light source or reflection is in the frame.)
Pic two - could be a metering issue. Try changing the (cog wheel =>) metering setting and / or exposure level.
Yellowish photo is the result of incorrect "white balance". Change the white balance setting to incandescent.
I'm using both the stock ICS camera and camera zoom fx. On my previous phone the fx produced much better photos than the stock one. On my G - Note I don't see much difference.

Yes you are supposed to remove it. It does say so in the instructions that came with your phone. Check the camera after you have done this.
After posting the camera comparison between old and .257 firmware I went out and did some more testing. This is one (actually, one of the better) shot done indoors at ISO 250, manual, slight +EV, 8MP 4:3.

I have boxed the three main complaints with this image:
green: heavy artifacts at color bridges, this is likely still the same issue of oversharpening and next-pixel balancing getting into each others' faces
red: in flat color areas it introduces huge noise
orange: fine detail such as faces is washed out and unusably so
Three things are different here: I'd used the phone for a while and it had gotten a little warmer than it'd been when I took the outdoors photos. In general do I notice a distinct reduction in image quality as the phone gets warmer, I took the same picture twice, sandwiching a ten second video (and we know how hot the phone gets from even short video). After the "your phone is too hot" message went away I took a second picture and it looked like crap. It's indoors, ISO 250 instead of 50 ... and it's a very color and detail intensive image.
But the two girls at the back still look fit

That's a tricky shot to get because of the back lighted window. Ideally a fill flash situation but not an option in your case given the apparent distance. It isn't surprising to see the problem areas you noted tend to cluster around the window. So how do you find the detail in the rest of the shot where the food is for example, its hard to say anything more because this is a downsampled image with no orignal provided.

Did you use spot metering here ? Where you metered off will influence how the detail appears. Its properly exposed from what i can see. Nice shot

I've seen mixed reports about heating when using the camera. Some say it does not heat up too much whereas other say it does. had chatted with someone about this and was told even videoing for ten minutes did not heat it up too much. Too much is relative here with other devices i suppose.

That's why I avoid making statements about exposure. What I am attempting (and I think I am being successful) to show is the introduction of fringing, halos, artifacts, oversharpening noise, and next-pixel supersample blur. This is by the way not a downsample, it's a 1:1 100% crop (as, I believe, any camera comparison should be. Worse are those passing off AutoAwesome and AutoEnhance pictures as "in camera," but that's another rant for another time.
I had a chance to chitchat with some Sony engineers on Saturday and they seem to be reluctantly aware (and considering they're dogfooding 4.3 right now, I think we'll see little improvement in that arena) of the next-pixel issues and artifacts.
Let me make this clear: I don't think this is bad camera mojo. It's acceptable (5th after iPhone, Nokia, and Samsung Galaxy S4 isn't all that bad) but given the amazing hardware we have it makes me sad that we don't get better.
Also you did not mention whether this is a 20MP or 8MP photo.
I wondered whether there was any advantage to taking a 20MP shot and oversampling on a pc to a lower resolution. Whether that may produce a better photo that in-phone as pc has more processing power and also more time to work and produce a better quality image. I understand that the oversampling is a chip level implementation so its quick whether any advantage can be gained doing this in post is unclear to me atm.
The thing about exposure is if there is enough light or the sensor was more sensitive then would those halos, artifacts etc be less. You got those artifacts because perceived light was lower than ideal. I might take a worse shot than you did with that picture where it could be even more pronounced. If there was a way to lock exposure like on other cameras do we get a better shot or not.
The answer which you do not want to hear is i would try to avoid that window during framing the shot. Its too hard to fix without a fill flash.
As for capabilities of Z1, i look forward and hope to see manual shutter speed control. If you compare with procamera on lumia that's the only parameter missing in the sony manual interface.

The other thing about exposure is, however, that the best way to establish the (non-scientific) usability of a camera is to aim it around and take pictures of things the way people would, then look at them and ask yourself: would that make me/them happy? Heck, go to Walmart and print some glossies, whatever, find out if you can make photos you'd share.

Lumia's HDR stitching is more accurate and it doesn't fall off along the edges in luminescence. Where the Z1 has it beat is in color retention in lower lights, though.

Would like you to comment on the other areas of the photo. Since you did not mention it do we assume the three areas are the only ones you were not satisfied with. For me the cluster around the window indicates a backlighting problem. underexposed subjects etc. Though i have to say you got a very well exposed photo there. So as to make me think this is the best that one can expect under the circumstances.
Will you tell us how you took that photo, back light scn mode or spot metering ?

I thought I was the only one.
Kept reading everyone say the new firmware was a big improvement for the camera but every photo I took looked grainy. I took a photo of 2 of my boys yesterday in low light. Had -ev and it was the first 'decent' picture I had taken since I upgraded the firmware.
Then I realised that one of my kids was sharp/clear, but my other boy sitting beside him was out of focus.
Maybe he moved slightly and because of the longer shutter speed it caused the problem?
Although that's still only one good pic out of maybe 50.
It's not a big deal, I'll just downgrade the firmware after work as before the new firmware every photo was great.
Low light as well as sunny conditions the camera was a boss.
Another thing, my viewing angles are perfect.
Why do some Z1's look **** when viewed on a slight angle AND benefit from a newer firmware, and others look no different when looking at the phone almost flat AND suffer after a firmware upgrade?
When I check out my pics/videos from a mad angle the screen is bright as ****. I've seen footage where the phone is tilted and the screen looks ****. Definitely not the case with my phone.
Have they all got different parts in them?

I am starting to wonder if they do all have different parts I can confirm there is a difference in screens as I bought two z1 phones just for compare and I found one had a better screen with more contrast and saturated colours. And the one with the better screen had a slightly better camera too. But this new firmware really pissed me off for me it was a huge step backwards the camera I found to be a lot worse as I have said earlier. The battery life on the new firmware I found to be pathetic and also the screen colour I found to be worse. The only thing it did fix was the screen going all black but back light staying on. How ever I got random reboots twice on the new firmware.
Now on the other hand my friend bought a Samsung note 3 and the camera on that performs far better then the xperia z1 also. Im starting to wonder weather I should change to a note 3 as im starting to feel im just wasting my time with sony. The software engineers they have working on the firmware updates need to be shot. How hard can it really be to make a good firmware???? What is sony doing???? I suspect they will never get it right for everyone because of different parts being used all the time.

But this new firmware really pissed me off for me it was a huge step backwards the camera I found to be a lot worse as I have said earlier. The battery life on the new firmware I found to be pathetic and also the screen colour I found to be worse. The only thing it did fix was the screen going all black but back light staying on. How ever I got random reboots twice on the new firmware.
Now on the other hand my friend bought a Samsung note 3 and the camera on that performs far better then the xperia z1 also. Im starting to wonder weather I should change to a note 3 as im starting to feel im just wasting my time with sony. The software engineers they have working on the firmware updates need to be shot. How hard can it really be to make a good firmware???? What is sony doing???? I suspect they will never get it right for everyone because of different parts being used all the time.

You bought 2 Z1's so you could compare the screen?
Really?

yes and they both had a very similar serial numbers but the screens were different, I have sold the other one now tho and kept the better one.

I've never had two phones of the same model with screens that look identical side by side. I'm sure the same applies to other displays and also TVs, which is why anyone in graphic design will pay to have monitors calibrated properly - and when you have video walls, these also need to be calibrated so one panel doesn't stand out.
But on their own, it's hard to tell which screen is 'right' or not.
I love my Xperia Z1. I have nothing to complain about aside from speaker and viewing angles which could be better, still it's not bad and improves on the Z. And the viewing angle issue seems to be less visible when you play a video. The only thing the camera is lacking is optical image stabilization. The focus is sometimes hit and more miss too. But overall, pictures are stunning for a phone (even in low light) but maybe I don't set the bar high enough. I've had the old and new firmware, was already happy with the old one and now I am happy with the new one. I quickly compared pictures with an iPhone 5 and it's easily on par.
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?

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.
