[Q] Line in Photos

Has anyone noticed this in their camera? You take a photo in low light and a line appears near the edges of your photo (only after you've shot it). I can consistently reproduce it. I'll get mine RMA'd, but was just wondering if it was just me or do other people have it? It doesn't show up at all in more well-lit conditions.

A couple more for Christmas
It seems like a software issue to me, making me think that maybe other people have the problem too. One of these shots shows lines on both ends

I just took a few quick photos with mine and I don't seem to be having that issue either. Have you tried restoring it first?

Weird, I get that too. Only in very dark conditions though. Not really bothered about it though tbh since low-light shooting is something I'm definitely avoiding with this camera.

Nothing seems to fix it. I've called for an RMA. It's worrisome that OverTheBelow has it too. I think everyone should check. The way I've been able to reproduce it is to have the camera take a picture of a dark area (not pitch black) and make sure either the top or bottom (whilst holding it in portrait) is completely dark. So the image you capture has to have something slightly illuminated in the middle, but the edges are black.

I just tried it on another Nexus 4 and got the same results unfortunately. Is this a common issue? Has anyone else experienced it?!!

Front Camera Low Light Pink/Purple tint..

Anyone got a purple overlay on their front camera when there is no light?

I get heavy purple or blueish vignetting with the front camera in low light, but only with the stock camera app.
First pic is from stock app, second one is from Google Camera.

Does anybody else see what Fuzalert2k sees when the camera is covered, i.e. dark? That means the image enhancement algorithm goes crazy in low light conditions. Does your camera work normally otherwise?
PS: there's already a thread on this: http://forum.xda-developers.com/z3-compact/general/camera-pink-spot-poll-t2933507/

Yes, the purple hue is also apparent in not-so-low light as you can see from my sample.
No, it's not the same phenomenon at all. This effect is only visible in the end result picture and it's the entire picture rather than just a spot within it. This is also not related to white balance, just seems to be a problem in the post-processing of the stock camera app specifically.

Yeah definitely not the same thing.
Look's like I'll be using Google Camera in future.
I must say Sony really dropped the ball on the Z3C camera software, and have yet to fix it or even acknowledge it.

I come from the HTC One.
The "pink hue when dark situations" was a well known problem there.
For soem time HTC used faulty camera sensors, which caused this problem.
If you experience sthis problem with your HTC One you can send your device in and get a replacement.
I hope that this is not the same wit the Z3Cs.
I for myself can't reenact this behaviour with my Z3C.

You are trying it with the front facing camera, are you?
It wouldn't make sense if it was a faulty sensor because it only happens in the stock camera app.

Now went into a completely dark room.
You are right, with the front cam, there is little bit of pink hue on the edges.
Yes, it is very "good" that it's only visible with the stock app.
Therefore the sensor should be okay.

Galaxy S6 Camera Pink Tint/Purple Flare Issue [ISOCELL PROBLEM?]

Hi all,
I just wanted to start a new thread regarding galaxy s6 camera issue, particularly about the pink tint/flare at night shots.
This is well known issue for HTC M7, and I did not expect the same issue from Samsung.
Basically, the camera is fine at daylight shots, but at night shots it will produce pink tint or flares around the corner edges. Sometimes the whole photo will just look pink.
See the attached photos for example.
I have taken a photo at the same location with iphone 6. As you can see it is so much better reflecting black colour sky. The s6 camera fails miserably at low light shots.
Even in the pitch black room, it will produce this pint flares.
I am wondering whether this issue is going to be massive one, just like for the HTC M7 handset (its thread on XDA runs very very long).
I hope this is not the case for s6.
I have returned mine for replacement. I'll report back whether the replacement unit is faulty as well.
This is going to be my 3rd replacement. First two times had a bad screen with yellowish tint. I have to say I am very disappointed with Samsung's QA.
By the way, my phone was 64gb, ISOCELL camera.
Today, I have visited many different network stores and retailer shops to to see if I can replicate this issue on the display models.
When I covered the camera lens on the display models with a cloth so that it shows total blackness, none of them exhibited the issue I have. Same experiment on mine will produces these pink tint.
I have checked more than 15 display models, galaxy s6 and s6 edge, in different stores and it surprised me they all had Sony sensors.
They were all 32gb models.
A friend of mine has a 64gb galaxy s6 gold colour as well and he's experiencing the similar problem, but not as bad as mine. This leads me to believe, perhaps the issue is only with ISOCELL units.
If you are experiencing the similar issue, could you please post what sensor you are using?
Thanks

I only have the pink tint issue in the centre of the screen. All my s6s have it in the centre,whether Sony or Samsung

I forgot to mention that all settings were set to auto.
Even in the pitch black light condition, I get those pink flares around the edges of the photo.

Not the same issue then, surely?

This is with Sony sensor

From a Isocell. Did the cover the camera thing, no pink tint.

Maybe if you talk about build quality, I don't know. I would disagree though if you meant picture quality.

I have the Isocell and I see NO pink at all. I did have the M7 with the pink issue and I know exactly
what you are talking about. Absolutely NO pink cast in any low light shots.
CC

Looks like amp glow or noise coming from somewhere, turn the ISO down and it'll stop that, perfectly normal when the ISO is being boosted to stupid levels.
What do the image properties say on the originals? What ISO are they set at?
These things aren't all built equally either though, maybe yours is getting more interference from somewhere.

Every photo was taken with auto mode setting. Tried different locations at night to see if they all produce this pink cast and they all did.
I don't play with ISO or any other camera setting on a smartphone. For a smartphone, I just want to take it out of my pocket and then take a shot.
I tried lowering the ISO and it does reduce the noise and pink tint; however, the photo then becomes all dark. What is the point of having a F1.9 camera sensor if you can't even take a brighter photo at low light conditions compared to an iphone..
Also, when I do that covering the camera lens thing with a cloth, mine produces this pink cast whereas the display models did not. Display models produced pitch black photos without any pink cast like the one Aletheia posted above. All settings were set to auto mode for this "experiment".
Since Aletheia's camera sensor is ISOCELL, I wonder if this pink cast issue is not related to camera sensor types. Mine could be just faulty.
I would like to find out though how many people are having this problem and what percentage of these people have got ISOCELL sensor.

This is what I got from the display models (all setting set to auto) and no pink cast at all.
MIne is just un-usable at this stage at night. Every photo gets this nice pink cast..

Non problem

Okay I tried it for you and get a little of the pink stuff. I think it's normal because the ISO is boosted above 1250.
If someone is willing to do the same with Sony to compare, that'd be great.

Here's a shot at ISO800. No pink ****.

I still see overall pink cast on the photo to be honest.
Can someone with Sony sensor take a photo in the pitch black condition with setting set to all auto and see if it produces any pink cast.
The display models I tried with showed no pink tink whatsoever.

Here I have compared s6 vs iPhone 6.
Both phones had all settings set to auto.
Left is s6 and right is iPhone 6.
I don't know if s6 is having trouble with auto iso or something. For me I have to decrease the iso significantly to get the pink cast effect to minimal but by then whole photo becomes darker than iPhone.
Look at the difference when you take a photo in the pitch black condition.
Clearly something is not right with my s6. All settings were set to auto for both phones..

Took some photos with iso set to 100 and pink cast is still present (more obvious if you turn screen brightness to max.)
I am concluding this is sensor related issue at this point.

V20 Bug - Purple Shadow when Taking Night Pics with Wide Lens

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?

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".
---------- Post added at 05:15 PM ---------- Previous post was at 04:59 PM ----------
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.

Ultra wide angle camera question

This is my second week with this unit and it's awesome so far! Took some time for the battery life to get up to par, but got that sorted out and now it's a beast!...like the title suggests though, I do have a question about the ultra wide camera. Can someone try going into a dark room, covering the camera lens when the ultra wide camera is activated, and see if you notice light bleed on the view finder when in 3:4 aspect ratio and no filter on? I notice slight light leakage onto the screen if you look around the edges of the viewfinder. You don't have to cover the lens because it is noticeable in really low indoor light conditions or if the room is extremely dark. The other two lens under the same conditions seem fine. It's not a deal breaker or anything, nor will I return the phone, just wondering if anyone else notice. It's very slight. In decent to good light conditions, you don't notice it at all. And I will say that it doesn't show on pics at all. This is just my OCD kicking in lol. The cameras are actually the best I've used on a phone!

I decided to take a screen shot. Take a look at the upper left hand side. Do you see the light leak? With the other camera lens, the viewfinder is pitch black to match the pitch black scene. If indoors and the light conditions are bad, you'll see the distortion on the viewfinder, but the pic will turn out perfect. Only if you do motion picture do you see it a bit. Anyone have this or an explanation? Definitely not enough for me to return the device, but just wondering if it's normal? Zoom into the photo I attached and you'll see it at the top left.

No one can quickly try this and confirm?

Do you have a camera protector applied?

No, no protector applied. When I called Samsung, the rep told me it's normal and her unit does the same. I still don't know. But if you tested in a dark room and you don't get it, that means not every unit has it.
