Nougat camera bug - Huawei P9 Questions & Answers

Hi,
first of all sorry for my bad English. It is not my mother tongue.
I have updated to Nougat (361 EU cust) and I have realised that there is a bug in the camera. In pro mode, when you set ISO manually, the shutter speed doesn't go below 1/17 if set automatically. That happens in low light situations. Also, if you try to set manually speed shutter, what you see in the screen doesn't get refreshed, so you don't know if you are exposing right. And more, in that situations Raw archives get so much noise and you aren't able even to correct that in Lightroom.
Also, in normal mode, in low light situations, the camera increases ISO but it can't change shutter speed more than 1/17.
Some others are suffering the same. We are talking about that in a Spanish forum. Do you suffer the same bug? Could you check it?
Thanks in advance
Here ISO is set manually and speed automatically https://goo.gl/photos/7cpoVJ7HNL4W5JZx6
Raw. ISO and shutter speed set manually, but calculating. The screen was as in the previous photo https://goo.gl/photos/2BU1sX5v9Tdbae3u9

[Q] Best manual mode settings for everyday shots?

HI, guys. I have a new Z1 on the way. I have read and seen comparisons that claim that the auto modes introduce a lot of noise and that, while the camera is capable of great shots, the software often lets it down.
I'm wondering if anyone can tell me what the best manual settings are to use. I know they will be different for each setting (dark settings, etc.), but is there a go-to group of manual settings that you use most of the time rather than superior auto?
Thanks!

In manual mode you must stop breathing to not shake the device and capture best detailed photo with less or no noise.
You can also disable flash and use exposure to capture bright photos without flashlight.
You can select manual ISO, which is for light sensitivity. Or....
The ISO number is how sensitive to light the camera
is. It's descended from film cameras, then it would be
how sensitive the chemicals were. The higher the ISO
setting the more light your camera picks up, useful
for low light conditions. However, as the ISOs get
higher so does the amount of 'noise' (visible pixels
that aren't supposed to be there) on your photos. It's
up to you to decide what's a suitable level of noise
and how sensitive you need your camera for each
particular photo.
in other terms
The ISO function sets the light sensitivity of the
camera's image sensor (this is similar to the speed
rating of film. The higher the ISO, the more sensitive
the image sensor and therefore the possibility to take
pictures in low-light situations.
If you find the camera is using a shutter speed that is
too slow (1/60 sec. and slower) to handhold the
camera steady and shake-free then you might select
the next higher ISO which will then allow you to
select a faster shutter speed.
F-stop is the measure of the aperture setting on a
lens. The greater the number, the less light it allows
in, which means the aperture gets smaller, making the
depth-of-field more extensive.

LOL, we can't edit aperture and this guide was not only for Xperia Z1 's manual mode but every camera is.

[Q] What are the best camera settings for low-light situations?

I'm coming from an LG G2, which had a great camera in low-light situations. I noticed a knock on some reviews for this camera in same situations, and I tried it out a bit and my pics look a little grainy. What are suggested settings for the camera? Thanks.

First, to remove the noise from your photos i suggest you to use the app 'A Better Camera' which has a good noise reduction process, once you downloaded it go in night mode, then go to 'other settings', then go to "shot mode settings", "night", "overnight processing", set noise reduction to maximum and shadow elimination to none, and tick the saturation check.
If you prefer Sony's camera use these settings in manual mode:
Exposure: one or two bars below value of 0
WB: auto
Resolution: 15,5 mpx
Focus mode: multiple autofocus (i think that's what it's called in english)
ISO: This is the most important setting. You can set it to 100 or even 50 to avoid noise and artifacts caused by heavy postprocessing by software. But, the lower the iso, darker the image will be. So on a sunny day it can be 50 od 100, On a cloudy day, a bit higher and in night photos 800.
Metering: multiple
Focusing: When you want to take photo, put object you want to take photo of in the middle and half press shutter button. When squares turn blue on places you want focused, keep shutter half pressed and you can then move your phone to left, right, up or down and not losing focus. That way you make your composition. When you think you have your scene set up, finally press the button all the way.

Camera tips and tricks

It seems some camera options are not very well documented. Thought I would start a thread to share tricks to help improve photos. There is another thread for tips and tricks but that one focuses on other things. Since camera is one of the highlights of this phone I figured a dedicated thread was worth it.
Here are a few I found. Feel free to share yours!
1. When tapping to focus on a point, if you do a long touch instead, it will set a focus point but add a second movable frame for exposure so you can have an exposure point that is not your focus point (IE focus on someone but expose for highlights)
2. If short tapping to focus, you can then tap/drag the focus point up or down to adjust exposure level (exposure compensation).
3. From my early tests, it looks like the camera hdr is better at recovering shadows instead of highlights. When having high contrast scene, change exposure so the highlights are better exposed when looking at picture frame. Shadow details will come out better (don't over exaggerate this or shadows will remain too dark). Adjusting exposure for shadows never seem to recover highlights properly.
4. I've seen some reviews where pixel 3 has a better exposure using their night scene function. If the mate night function yeilds results too dark, you can force the time and Iso to use (tap the icons in bottom left and right). So far I found that if I look at the picture info and see the auto mode exposed say 4 sec with Iso 400, usually keeping 4 sec but doubling Iso (800 in that case), will produce a better exposure similar to the pixel. I don't want to get into color/detail comparison between the 2 devices.. This is just to get a better exposure. Guessing they'll sort this out in a future update.
For now that's what I found that didn't feel intuitive.
Please share your findings!
Let me share my suggestions:
1. In case of pro mode ,shutter speed is restricted to 30s of exposure whereas night mode can give up to 52s (max I have seen) exposure.
2. You can try different light painting modes to achieve low-light shots as well. I tried with star trails and got good results ( but exposure gets throttled and(or) locked at some point.
3. in Pro mode, If you are taking low-light snaps in an enclosed area such that your flashlight can reach, then you will get very good photos for reasonably smaller exposure times.
4. Use tripods for all night shots (bluetooth trigger will make it even better), don't rely on stabilization unless there is ample light and that exposure time will be around 1/125 , because even night mode can be affected despite the claim that OIS stabilization will be sufficient.
5. lowering the exposure while taking close-up flash photography will help in partially retaining data that would have been lost due to flash overexposure.
Thanks,

Stock Camera HDR

I have the unlocked Exynos variant and on the latest pie update. When I set the HDR(Rich tone) option to always enabled, the resultant shots don't look like they have any HDR processing applied, but if it's set to auto, the same shot comes with much better controlled highlights.
I'm new to this phone, albeit this is my first Samsung.
With previous phones I've used, whenever HDR was forced to on, it applied HDR to every shot taken.
Am I missing something here? Any help would be much appreciated.

Hi,
i have read on some website that when you set HDR to on but not "Always apply" but "Apply when needed" the photos come out better.
Unfortunatly i cannot find that site atm.
Also i often pull down exposure a bit in bright sunlight because despite hdr some hightlights get clipped sometimes.
Just in case you dont know, exposure compensation works by tapping on the viewfinder to focus, then use the "bulb" slider that appears briefly just above the "trees" ( wide-angle - telephoto switch). It can be hard to see in bright light though.
Hope that helps a bit

Question Camera Settings

Hi,
Does anyone know what the different 'picture quality' settings in the camera app mean? There are 3 settings, low, standard and high. What do these actually do, and is there one that you prefer? A separate setting exists that says Enhance Image Quality. Isn't that kind of redundant, and should this be kept on?
In a lot of youtube video reviews for this phone, they compare the photo quality of the phone, and then they say something like, after 4-1 binning, the photo looks much better. If this is the case, what settings do I need to set on the phone to get the '4-1 binned' quality?
Cheers!
Picture quality is so obvious, I do not have numbers but it is about resolution and number of pixels. Try to take the same photo with different quality then try to zoom in photo to understand.
enhanced image quality is a nice feature that I have turned off, I like raw images than enhanced and I hate that sometimes it goes to night mode while I want to take low light photos , but it definitely is a great feature.
Not sure what is 4-1 binning and never heard of it.
My settings are the following:
HDR AUTO
AI OFF
9:16
Under camera settings:
Mode section: motion capture on, the rest are off. High quality picture.
Under preserve settings, beautify off**** was passing me off before update.
That is more than enough for me for images.
Hope it helps
