Hey guys I have found another tweak. In our build.prop I noticed ro.mediacapture.torchintensity=40. Upping this increases the flash brightness in the camcorder. Also ro.media.capture.flashintensity=70 upping this increases the flash brightness in camera.
I confirmed they made a difference. Tried last night taking a picture at stock setting, then a picture with it upped to 100. Then did the same with the camcorder.
Try raising those values to what you feel comfortable with and let me know if they have helped you guys.
WARNING! Obviously too high would kill battery quicker if taking many shots or long videos. But this definitely works.
Heres an interesting concept. Can we adjust a setting to get 8mp widescreen? If possible would be amazing! Havent been able to figure this one out though.
Be careful turning the flash to high.you could burn the led out.

I hear ya, but considering led last alot longer than regular lights I wouldn't worry than much. Besides that why we have warranties.

They may last longer under normal circumstances, but oh man can they die fast. Be VERY careful with how bright you make it and for how long it stays on for. You an burn out the diode very quickly.

Dont have to put it at 100 if you dont want to. Just pointing out that it most definitely helps. Make it what you feel confortable. It definitely improves low light video and pictures.
upping the brightness wouldn't be so bad if there was a way to deflect the light. taking camcorder pictures with the flash on is great in most any light situation, but because it's a direct light, you get washed out colors and red eye problems.
i wish there were an easy to deflect the light too.
Well its adjustable so you guy can fine the setting that best suits you guys. Keep in mind its only a phone if we want better quality we should use cameras. That being said, upping these values at least gets us a respectable picture or video in low light, a picture worth keeping that doesn't just get deleted after we go back and check it.
I'm getting some seriously nasty bars during slow motion recording (I attached a screen shot which isn't as bad but when it's a video the bars move all around and are very distracting) Anyone seeing the same thing or am I looking at a defective phone? I already swapped out phones yesterday due to a stuck pixel, but best buy has been very easy about it thus far. Just wanting to see if this is hardware or software, thanks!
Yep, exactly the same here. Gets worse the more the sensor gain ramps up.

Checked the sprint store demo and a best buy demo, All the same. Must be a low light issue. Oh well, Guess most of the time the feature will be used in the daylight (although this may be a bad thing when trying to slow mo some epic beer pong matches)

Figures, seems like it would be a hardware issue, but maybe there will be some magic firmware update that will help.
Most serious hd cameras require a lot of light, so this should be no surprise when recording show motion videos. Just be sure to have adequate lighting in the future

I haven't looked closely at the example yet otherwise I would have put my 2 cents in earlier.
I work a lot with cameras and know them very well. One thing to keep in mind is cmos sensors don't expose every pixel at the same time. This causes what is known as the jello effect when you move quickly left and right. This can also cause what is known as rolling shutter. I believe this is caused by the shutter speed in combination with the way cmos sensors work. When I get back from this weekend trip, I'll see what is going on.
At work I have a professional Sony video camera with a backlit cmos sensor. If I drop the shutter speed down too low to help when it's too dark, especially around fluorescent lights, I get brown bars rolling across the image. It's just a physical limitation of the sensor no matter the camera. Some hide it better than others. I hope this helps clear this up.

This is nothing like traditional noise caused by high sensor gain in low light. We're talking dense horizontal lines only in slow motion recording, which I'm guessing is 120fps? 60 fps mode works fine. I've seen examples of slow motion video recorded by the euro version in low light that didn't have this problem.

That doesn't eliminate it as a cause. The example you saw could have been in better lighting conditions than you thought, or the euro edition might have had older firmware that didn't let the ISO go as high (thus, the whole image would appear much darker, but less noise).
120fps slow motion means the camera has to use at least 120th of a second for a shutter speed. This is relatively fast for a smartphone camera, so it has to bump up the ISO to compensate. If the light is especially low, it will have to move all the way to the upper bounds of its ISO capability to get a usable image. Meanwhile, a 60fps video will have MUCH more time (2x is a lot of time) to grab light, and so it doesn't need to force the ISO so high.
It's extremely unlikely that a firmware update will solve this issue. All they could do is just force the camera not to use that high ISO setting, resulting in slow motion videos that are too dark instead of too noisy.
(Also, BTW, this has nothing to do with the jello effect)
How do you do slow motion video recording? When I have the video camera on, there aren't any menu options available.

Thanks for adding. I hadn't had a chance to even look at the example posted but felt like it should be addressed by someone. I'm out in the middle of nowhere right now, video streaming isn't always going to work well here.

The euro demo was in CONSIDERABLY worse lighting, without question. I don't have time to look for it now, but it's on Youtube.
The Euro version just got an official update regarding several problems. It also included a low light slomotion video upgrade

I'm getting a stuck blue pixel when taking photos in low light... is anyone else experiencing this? The blue pixel is showing up in the actual photo taken, so I'm assuming it's a problem with the sensor.
Daylight photos aren't exhibiting this behavior.
My Z is a few months old now, and has been functioning fine so far. Now and then though, the camera goes completely nuts- by taking photos with yellowish/brownish bars across it. The bars are visible on screen too. I can't figure out what's causing this (I've wiped the back panel), but it seems like it only happens for indoor shots, especially when the subject of the photo is close to the camera (about 20cm away).
Is this something to worry about? Are there many other users with the same problem, and should I send it in for servicing/ to get a replacement unit? It's still under warranty.
I'm on build 101.1.A.1.253, running stock 4.1.2, for what it's worth.
Get it replaced.
From me to you.

Yeah same here, it seems more the logical. The shop you bought it can't call that a good picture.
I done some research on this
this is under fluorescent lighting @ ISO 1600
This is under fluorescent lighting @ ISO100 (still a little brownish)
This is under fluorescent lighting @ ISO 400? With HDR ON
This is under sunlight @ ISO 1600 With HDR ON
I have tested also on ther condition, did not upload it/ deleted
but i can sort of deduce this
1. The brown bars are caused by the fluorescent lighting that have a frequency clash with the camera refresh rate.
2. The problem seems minimize at ISO100, appears slightly @ ISO200 but worsen once over ISO400
3. The pictures above is taken at close range ~ 8cm away with the phone place on an elevated box.
4. with fluorescent lighting, the HDR ON affect on as low as ISO100, and causes the ghost/double image and really tits up on higher ISO. This issue lessen with natural sunlight where the image maintain crisp until ISO 1600.
5. I cannot use the self timer as the flash light for the timer sometimes f-up the focus (this is a real f-up)
6. There are still other modes i have yet to test out such as burst etc

I didn't bother testing as much as you did, but all that does seem to make sense! Did some searching and it seems like some Sony cameras have this problem (point and shoot, or DSLR, I can't remember). It is an indoor only thing like you said, under fluorescent lighting.
Wonder if this qualifies as a bug or a hardware limitation...
Hi all,
I have bought the phone yesterday, stock, unlocked latest software.
Look at those pictures, especially white birds... Ridiculous, even some white tint over seagulls, zero details on white feathers.
No sun, normal Irish day..
Please comment... Stock camera settings.
http://db.tt/BnlPNQqy
http://db.tt/PTM8fnBE
are you on 1.29?
the photo`s are overexposed, the one sets the exposure on what it is focusing on, so i would have though it focused on the dark water and raised the exposure, that`s is why the white birds are overexposed, if you focused on a white bird, the one would reduce the exposure, and give more detail on the birds.
You know you can touch the screen to focus, but there is a setting in the menu to take a photo automatically when you click on an area of the screen.
I wish there was an total area exposure mode instead of the focus spot one.
John.
that ^
I'm not an expert but, I think you just need to focus manually (press on the screen to focus as Tinderbox said) to avoid an overexposed picture...

It's called metering. When you tap on the water to focus (dark), the camera turns the light up so that the water is clearly visible and perfectly exposed. But since you're making dark brighter, the brights will naturally be even brighter. You want the feathers to show detail, you tap on them and it adjusts the light so that they are darker and you can see detail at the expense of even darker water.
Your best bet in these kind of high contrast situations is to use HDR mode. It takes 1 under-exposed image (dark) and 1 slightly over-exposed image (bright) and merges the 2 together. Dark areas will be brighter and bright areas will be darker, giving the image a little fake look, but evenly exposed throughout.
On dSLRs, HDR actually takes THREE images to combine (sometimes even 5). This gives the processor more choices to pick and choose the best parts of each image to merge to a final picture.

Thanks for your replies, guys.
I don't remember now, what I have been focusing on - was it the swans/seagulls or dark water, pavement. I think I tried both, focusing on different areas of the screen and the result was the same.
Same goes for videos, birds are overblown and shine like some white lanterns...
My firmware is 1.29.401.16
yeah do some metering and try different types of shots,

Just some samples to explain my previous post. First pic is me focusing on the wall, which is dark. The wall is now not but my lightsource is completely blown out.
As one pic shows me focusing on the light. Since it's bright, the camera has to darken the whole scene so I can actually see the object I focused on, turning the rest of the scene dark.

Camera fault?
It's just the camera. I tested it against an s4 and an Xperia z. Indoor shots were way better on the one than either of them but both beat out the one hands down when it came to outdoor shots. I have tried everything and can't get a really good outdoor shot. I would like to see the result of someone porting the Xperia z camera app to our device but I don't know if it is possible.

Hey guys,
The problem is, that some extra white/bright objects are too small for the camera to catch focus for and adjust the settings.
I played with settings a bit over the weekend and the camera focuses OK on brighter objects, as long as they are big enough...
A bit of a shame, nor my Lumia 920, nor even galaxy S2 has problems like this... I guess, I can live with it, though
Hi all I just received the OTA for Android 4.4.2 so have put together a before and after comparing 4.4 to 4.4.2 for the Nexus 5 camera. Includes some full crop images and video capture as well as the all important autofocus test.
Very pleased with the results looks like Google have made big improvements all round to the camera.

I've tried it in dim light and find the noise to be ok, better than the S4 not as good as HTC One (to be expected)
ISO is ramping more aggressively in still images IMO but not a deal breaker, looks better than the S4 anyway.
The screen is really, really dark in dim light. And the video itself is also really dark.
Case and point, i went to a bar with my girlfriend to eat something. I decided to record something using the camcorder, and well. I'll let the results speak for themselves. It looked like the lights were out in the place. I wish I had thought to take pictures, because it certainly wasn't as dark as the video would lead you to believe.

I'm starting to think that we're all seeing the same thing and just coming up with different interpretations due to subjective differences. There's no other reason that everyone would be having such wildly different results using the same software and hardware.
All I know is that video recording on my phone in low light is MUCH, MUCH darker than it was on either 4.4 or 4.4.1. I wish I had taken some screenies before updating to show you.

Are the results with 4.4 much better? This has really got to be on the edge of what the sensor can do in video so the results don't surprise me.

Uhh, actually I remember I have another low light recording that I did on 4.4 when I was in a restaurant. Very low ambient lighting. The test was more to see the image stabilization during recording, but the lighting was comparable to the bar.

Those two videos have completely different lighting. If you took a light meter into those two places (restaurant vs bar) you'll find that the bar is really much darker.
I'm not saying that 4.4.1/2 isn't worse - just that these two videos don't make a good comparison.

What's funny is that I had spotlighting right above my head (direct, LED bright lighting) IN the bar at the table I was sitting at, which would make it look like stage lighting.
But it looks as if it's horrendously dark in there and all of the ambient LED's look like christmas lights thanks to the recording and the contrast of light sources. Trust me when I say it was a lot brighter in the bar than the video would lead you to believe.

That looks exactly like I would expect a video from a dimly lit bar to look.
I didn't think to take any photos at the time, but the difference between the photo viewfinder mode and the camcorder mode was incredibly noticeable, very similar to the screen caps of the viewfinders posted in the 4.4.2 first thoughts thread.
