Adjusting Brightness in camera app - Huawei P9 Questions & Answers

Hi,
I find that the camera really underperforms when inside under artificial lighting - shots seem underexposed. Does anybody know a way of quickly and easily adjusting the brightness of a photo before taking it. For example on an iphone you can touch to focus and then slide the bar to the right of the focus area to adjust brightness.
When touching to focus on the p9 a small "sun" image appears next to the focus point but this disappears almost instantly - i'm not sure if this is meant to stick around for longer so that you can adjust the brightness?
I know that you can hold to focus and then manually adjust the metering point, however this isn't ideal when trying to take a quick photo.
Thanks

You can use the little "sun" icon to adjust exposure on the fly. I've heard somewhere that in certain firmware versions the icon disappears very quickly (just like the little "iris" icon in wide-aperture mode). Maybe pretending that it were there and sliding up and down right next to the focus ring (where the "sun" icon shows up) still works even though the icon already disappeared from your screen. Apart from that, there's an exposure slider in the "Pro" mode, but that's not as convenient as the little "sun" icon.

[Q] Camera Auto Focus

I was was wondering if there's a way to make the camera auto focus without the need of touching the screen to focus it.
Its possible?.

Under the settings (gear on bottom left), first page, the focus type should be set to Auto Focus.
From my experience it automatically focuses on whatever is in the box on the screen... however if you want the focus to be on something outside of that area, then you tap on the screen to change the focal distance.
You can test this for yourself by taking a picture of an object that is close to you, keeping it in the box and not tapping the screen, then switching to an object farther away, keeping it within the box... both pics should be properly focused. Finally, take a pic with a closer object outside the box, then tap to select the object and change the focus... the closer image will be in focus even though it is not directly in the center of the picture.
Well, thanks a lot.
I already had the focus type configured as Auto Focus.
Tried taking some pictures and the focus seems to be well, but I think pics taken by touching the screen to focus the camera have much better quality.
Correct me if I'm wrong.
I would tend to agree with that... I usually tap the screen myself as long as I have time... but in a pinch when I just need a quick shot, then it's just point and shoot.

[Q] Camera Metering change from 2.1 to 2.2

Back when I had 2.1, one of my most favorite things ever was the ability to have the metering lock after focusing.
If I didn't explain that well enough, you know how when you tap the screen to focus on a bright and shiny object and the entire brightness of the image becomes darker? Well, the same exact thing happens on 2.2, however, if you move the focused point away from the bright and shiny object, it will continue to continuously adjust the metering depending on what the green focus square is pointing at, whereas on 2.1, it would lock the metering, so once you focused on an object and subsequently moved the camera around, the brightness of the image would not change.
I feel as if I over explained what I was trying to say, so, either deal with it or ask questions to clarify.
If anyone at least knows and feels my pain, let us suffer together.. or, get some answers.
Try a different rom. Some have some great camera apps.

[Q] How do you turn off auto-focus

As a "proper" camera, the unit seems to be missing some things I'd expect by default. How do you turn off auto-focus an focus manually... taking pictures at night - the stars etc - invariably the images are out of focus.
Also auto-exposure control - you can turn that off easily for images but for videos there seems to be no way to turn off the auto exposure - which makes the end product look very amateurish.
Finally whenever I go out at night, the LCD dims, I can't seem to stop that and it dims WAY too much?
Any ideas chaps?

It appears that you cannot turn Auto Focus off but you might be able to find a third party camera app in the Play Store that allows this
Settings for video are sparse it's true and again there is no control over the exposure etc.
I didn't notice the LCD dimming, The camera doesn't have an auto brightness LCD so I am not sure what's causing that. Turning the brightness up from the drop down notification bar is easy enough though.
Sorry these are not the answers you are looking for but we have to remind ourselves that this is a premium camera not a pro camera however.

Thanks for that. I will indeed look out for such an app. Agree with you that it's not a "pro" camera - but for example - on the iPhone who's video handling is equally dire, there's an app that completely compensates by letting you shoot 16:9 with auto exposure, auto focus and auto-white all turned off at the touch of a button. This camera really does need such controls to make it useful for anything other than "party" videos. Its a big disappointment that Samsung would miss off such obvious controls having taken the effort to make a special camera app in the first place.
there are only 2 focus modes as far as I can tell, auto and macro.
night sky shots have worked fine for me using auto focus though.
I made some nice pictures of a crescent moon without a tripod or manual focus, and it was sharp enough to see the craters on the moon.
using manual camcorder under expert you can set the brightness, and white balance for video recording manually(wb is under the settings gear)
lcd dimming: settings gear - general - display brightness
the settings gear is hidden under the > and the expert mode can be accessed through the mode button.
don't be so afraid to dig a bit through settings.
I often see complaints about missing/misbehaving features in apps when it's all available through a settings screen.
EDIT: apprentice: auto brightness works using the camera sensor, so it only works while in the camera app.
Thanks for that - so solved the LCD brightness, but I've gone through all the settings and cannot figure out how to turn off the auto-focus or the auto-brightness. Put your hand in front of the lens - and both kick in whether you want them or not... any ideas anyone?

As far as I can tell in camcorder mode, the one thing you can set - brilliance- is only relative brilliance - the exposure still bobs up and down like a YoYo.... making the movies look terrible - surely guys there has to be a way to turn this off?

Camera Exposure

Hi Guys
Does anybody know of a way to disable auto exposure? When I take pictures, often I want to focus on a particular area and 99% of the time that area seems to be darker or lighter so the exposure is adjusted automatically and I hate this as it often washes out images or over exposes other areas. I just want to be able to touch to focus and the exposure not change ... Is this possible?
Thanks

If you press and hold an area when in camera it will lock the AE/AF, the exposure and focus will now remain the same no matter where you point it. This will only work in 4.2.2 though (4.1.2 doesn't have this feature).

Thanks for the reply ... I have tried this but often I want to focus centrally and when you hold to lock it it still seems to over expose. I was hoping there was some Mod that might disable exposure unless you manually adjust it so you can touch to focus anywhere and whether it's dark or light, the exposure won't change.

Are you holding at a light point in the picture. If you hold at a dark point it will probably come out over exposed. If it's relatively dark I normally lock onto a street lamp or something else bright.

It varies tbh, I'll have to have a play with it and give it a full test.

Question Camera App Bugs

Found a couple of bugs in the native camera app so far. One of them I posted in another thread which is the inability to turn off the obnoxiously loud camera shutter sound. There are even slider toggles to do it found in two different places in the camera app, but enabling and disabling the toggle does not turn off the sound.
The second one has to do with the beauty mode when taking selfies. When using the selfie camera, if you select the beautification option at the top (the icon that looks like a girl's head), you'll see 3 options at the bottom: Origin, Auto, and Personal. If you select Personal, you can adjust individual settings for things like slim face, smoothing, eye size, skin tone, color and brightness by utilizing a slider for each option. Well with the SMOOTH option, the placement of the slider that you choose NEVER sticks where you want it. For example, if you set the slider to 30 (it goes from 0 to 100) and then go to another option like eye size, and then come back to the smoothing option, the slider will not be where you put it. From what I can tell, the SMOOTH option is the only option where the slider never stays where you put it. It's pretty maddening. I've tried to clear the cache and data of the camera app but that doesn't work. In addition, the slim face option is hit and miss. When adjusting it you can see it trying to slim your face the farther you slide it to the right, but sometimes the app bugs out and it goes back and forth from slim to fat to slim to fat, etc. It's just buggy.
In the multi shot mode the EXIF metadata is not correct. It seems that the EXIF data from one of the modules (the one in focus?) is written to the two other images too.
In the "normal" camera mode the "2x" module works in the 35mm equivalent mode what is about 1.2-1.3x.
In the manual and the 64MP mode the 2x module is cropped an upscaled so that the label 2x is matching.
RAW/DNG images from ProShot show that the "2x" module is in fact a 1.2-1.3x module with an equivalent focal length of 35mm.
Is is also a shame that the multishot excludes the 2x module and incorporates only the 0.5x, 1x and 5x module producing a huge zoom gap in series.
Firmware MyOS12.0.8_A2022PG_G LB camera slows down in video mode, shoots jerkily. how to fix?
