Rear camera too dark - Nexus 7 (2013) Q&A

Anyone else find the rear camera almost pitch black compared to front camera? I've changed various settings but it doesn't go any brighter.

Most units have the dark camera. Some have a brighter camera.
The best you can do is adjust the exposure setting.

I just posted in another thread that I had this issue, even adjusting all the setting makes very little difference when using the camera in video mode, picture mode is fine though, no issues with darkness etc.

Sorry I didn't see your thread, yes I have exactly same problem in video mode being darker than camera mode with the rear camera no issue with front one though, my bad I should of stated which mode it was in.

Don't know about the dark only in video mode issue.
What I've seen is most cameras look find in bright rooms, but in dimly lit rooms, everything is very dark. I just figured this was normal for this level camera, but then I saw a unit that was able to have the same image my eye could see, rather than being so dark it was hard to make out details.
That's when I came to the concusion there are different cameras or the same camera with different variances.
I could adjust the exposure in the dark camera to the highest level and get about 75% of the brightness of the bright camera, but never as bright. By bright, I just mean you can make out the details in the scene.

It seems to be more of bug though because it's also doing it on sphere & panoramic modes too, it's like it's automatically setting the exposure to -2 when your under unnatural light. The setting shouldn't be any different to camera still mode as all it does is stitch multiple stills together.

I went back and tested my camera in more depth.
When I turn on video mode, it ignores any exposure setting. Is it possible you have exposure turned up (not necessarily by your own doing) in the camera mode and when you switch to video, it doesn't honor the exposure?
Basically what I'm asking is, rather than video mode being dark, is it possible video mode is "normal", ie no adjustments to exposure, and camera mode has exposure upped up, possibly some change/fix that was made to account for an overly dark camera?
I know this makes no "effective" difference to you, but might explain why it behaves differently in camera and video/stitch/etc. mode.

Sometimes it also goes redish dark in picture / still mode too but that can be fixed by pressing home and then returning to it via recents, you can hear the shutter or lens reset.

4.4 gives a slight improvement, it's lighter now hopefully with another tweaked update it'll be fixed.

Camera options

There's a couple of options in the camera app that aren't entirely self-explanatory. Anyone able to shed any light?
Anti-shake: The manual says, "reduces image blur due to the movement of the subject of the photo or hand movement." Any ideas why this is disabled by default? Are there any downsides to reducing shake?
Auto contrast: The manual says, "provides a clear image even under backlight circumstances where intensity of illumination can vary excessively." Does anyone have any idea what this is doing? Is this HDR?
Outdoor visibility: The manual says, "allows you to take better pictures when outdoors." Anyone know if this does anything besides just make the screen colors brighter?
Anyone have any ideas?
Anti-Shake is an option to use to help reduce the effects of the camera moving while shooting a picture. I see no downsides to enabling it unless you like blurry pictures. It might reduce battery life a tiny bit more while using the camera.
Think of it as mouse smoothing in games, if you do that sort of thing.
Auto contrast is a nice feature (if it works well) that adjusts the pictures light levels in case of a dark subject and a bright background, or vice versa. It should help to make a better overal balanced picture.
Outdoor visibility has to do with the LCD screen itself. If you are outside on a bright day you want that on. It makes sure the backlight is on full and the colors are bright so you can more easily see the screen.

[Q] Better video camera app?

I'm running CM9, and it's been great mostly. Last night I was trying to take some video in a reasonably lit room. Not too bright, not too dark, just a room you'd be sitting in. Well, the preview in the camera app looked good, subject was easily visible, colors looked ok. As soon as I hit record though, it seems to close the iris down or change the exposure to "normal" viewing, which caused the image to become much darker. I'd like to be able to have the camera record with an exposure set at the levels the preview uses. Can someone recommend a video camera app with better controls for that sort of thing? Or tell me how to change the exposure on the video camera mode of the built in app? I didn't see a way to do so.
Thanks!

Getting the most out of my camera

Hey, I'm pretty new to my G4, and I was wondering how to get the most out of my camera.
I haven't downloaded any camera apps or anything, and just use the stock one. For pictures I take, I just leave the settings on auto, seeing as I don't know a whole lot about photography. How could I tweak the custom settings to work better under different circumstances and just get a better picture in general?
The automatic settings will give you great picture under most circumstances. Playing around with the manual settings will involve knowledge of basic photography concepts around ISO, shutter speed, etc. If you want to get into those, YouTube is the best place to start with tutorials

Depends how you define better picture. in low light the slowest shutter will be 1/9. is this the best picture at that light ? no. A slower shutter with a lower ISO will get a cleaner shot and will display more. But to use a shutter slower than 1/9 requires you to stabilise the camera some how.
a tripod is one way if you use slow shutters that run into seconds. The G4 can go up to 30 seconds. But to improve over auto's 1/9 a 2 second will improve things noticeably.
on the other side you sometimes want a faster shutter to freeze motion. A slower shutter creates blur and auto might not pick a fast enough shutter. The camera has no idea what you are taking a photo of just a rough guess. If the light isn't enough you will have to pick a higher iso to compensate. If its in daylight then only a faster shutter that might be in the thousandths of a second is required.
other times you want to fix the focus or auto focus won't manage it, this is where manual focus comes into it.
white balance determines the colour, auto white balance does a good enough job but at times can get it wrong, if it looks too cold for your liking a warmer white balance will add yellow. If it looks too warm a colder setting will add blue.
A simple tip is to tap on the screen on your subject before shooting. It will focus there, and it will also set the exposure based on that area. Making your subject sharp, and properly exposed.
But it only holds those settings for maybe 2 seconds, so take the picture quickly after you tap on the screen. Wait too long, and it goes back to assuming you want the center of the frame.
I do this even if my subject is in the middle, as I prefer to let it finish focusing before taking the picture. If it focuses wrong, I may notice it on the screen before shooting.

Black lines in high contrast pics with HDR on in stock camera?

Hi, this question is actually about an AT&T V35, but since that phone doesn't have its own sub and it shares a camera module with the G7, I figured I'd ask here. I love most things about the camera and UI, but when I take pics of high contrast environments, I get really nasty colors and black lines on every other pixel. This does not happen at all without HDR on. Any solutions or ideas? Stock LG cam, version 7.0.132.25. Here's a pic as an example, one is zoomed out, the other is full crop. I know going to GCam solves this, but I prefer the zoom UI on the stock LG camera.
Edit: It is not PWM in light power supply, as this happens with fluorescent and incandescent light sources and the lines are very sharp. The lines also occur top to bottom of the phone, meaning they are horizontal in landscape orientation.
Sorry if a V35 post isn't allowed here, please remove if so.

Abnormal colors on selfie camera in low light

Hey
So I bought the phone (Note10+ 5G) about 3 days ago and everything was working fine even the selfie cam
But today when I changed live focus effect everything get ruined especially in low light
In the viewfinder there is a color flicker and a part of the screen changes to green or red effect
And everything get worse in video
Here is a 2sec sample in low light:
https://drive.google.com/file/d/1-3bzKBjWNgb2OtRRSEwcwiGFniwd5d9b/view?usp=drivesdk
So what is wrong here?
edit / nevermind, watched the video and do not understand your problem...
live focus ? color flicker?
In live focus the effect green/red exists as part of the background effect. Your video does not show anything since there is nothing to focus on. You need a face for it to show anything correctly.
And you can change the live focus effect at the bottom of the screen, you have several icons for this and the far right icon is the red/green thingy.
If you cannot manage to get the settings right, just reset the camera (settings -> scroll down to initialize parameters).
Also, do not activate HDR+ for videos (available for 1920x1080 30p). This option is in beta and is buggy with many colour artefacts.
he's trying to take **** pics in the dark. doesnt like the out come. he thinks filters can correct small penis syndrome.
