[Samsung Galaxy S8 Themes, Apps, and Mods] IDan1109:
A little bit of boring theory

Introduction

Everyone in this thread is asking for what are the best options? The short answer is default. The long answer is it depends. To get the best results out of this mod you need to understand what all the options are and how they work. It is more similar to a professional camera where you have all the strange options to play with and you don't know what they do. You start changing all the values and then when you take a picture you are like "wut is this i took a picture of this beautiful panorama and it looks like a Picasso painting". To avoid that situation keep reading this post so you can understand what i'm talking about.

The basics

First of all before taking any picture you need to clean the lenses you are going to use. This seems to be trivial for someone but this are the results if you don't do it.

Clean vs. Dirty

The settings

Here you can find the explaination of what the settings do and how they work. I will add more in the future. If you don't know what shutter speed is or ISO google is your friend.

-Config. HDR+ camera

Nexus 6 HDR+ Auto: more dynamic range and quality (less noise). You can set all the Auto-Exposure modes but as downside you have the shutter lag so you should be careful to find the right time to shoot a photo with moving objects.

-Pixel 2017 ZSL HDR+: (ZSL = zero shutter lag HDR+)

Less dynamic range, and more noise in low light because slow shutter mode is NOT available. However it is much better in good/medium light if you make photos of moving objects, because it processes images already taken in the background. In low light, or high contrast scenes please use Enhanced HDR+

-HDR+ parameters:

It is recommend using one of the Pixel 2017 options, because they should be more stable regarding memory leak.

"High", "Very high" and even "Default" leak memory if pixel 2017 config is used.

Description for "HDR+ parameters": for example 8/10 burst means that HDR+ operates with 8 shot bursts. Portrait mode (ZSL) operates with 10 shot bursts at most. In my personal opinion Low or Very Low HDR+ are very similiar or equal to High or Pixel values but people prefer higher values for reasons uknown.

-HDR+ Auto-Exposure mode No-ZSL:

Everything that is No-ZSL means that will not work if "Pixel 2017 ZSL HDR+" is set for the back camera!

If you want to use custom Auto-Exposure and HDR+ for front camera you have to disable "Portrait ZSL mode".

"Slow shutter" will decrease shutter speed as much as possible in bad light. The result: much lower ISO and noise. Of course fast moving objects will probably get blurry more easily.

Slow shutter x8 is not stable for front camera but you can use x4 or x2. The max exposure time is 1/3 for the slow shutter x4.Sometimes you can get in trouble with x4 if you take a picture then you look at the gallery (black screen). But you wont have any problems if you take multiple pictures and then switch to x2 and look ad the gallery.

Selecting "Stock camera2 api" will get rid of rainbow effect, but dynamic range is poor, because camera can't underexpose fast enough if auto shutter control is on.

-Antibanding modes

Anti-banding allows the camera to avoid problems caused by artificial light sources that are not constant (flicker for want of a better description) these are typically florescent tubes but also multiplexed bulbs and PWM controlled LED’s (and your TV screen for similar, if not quite the same reasons) These sources cycle (flicker) fast enough to go unnoticed to the human eye, appearing continuous, they key word here being human. The camera’s eye (its sensor) can still see this flicker.

Only select 50hz or 60hz (dependig on where you live) in case of banding problems, because it can cause suboptimal shutter speed otherwise! Works up to 1/149 sec shutter speed.

-Denoise strength for HDR+ and portrait

Self explanatory. It will increase the denoise strenght for higer values.

For front cam you need to select about 2-300% to really see the difference. Back cam is much more sensitive to this setting.

-Underexposure multiplier (HDR+ dynamic range control)

Reduce below 100% to decrease rainbow effect. Should also overexpose if set to 0 with a good light source. Higher values means lower exposure.

-Samsung specific metering modes

Touch to expose is enabled by default. So won't have the touch to focus option. With "Centered" mode it will focus what it is in the center and then you can adjust the exposure by touching the area! This is a good option beacuse if you want to get the best results from HDR+ you'll need to adjust the exposure only and not the focused object at the same time.

-Samsung Live HDR mode:

Adds some dynamic range to modes where HDR+ is not available like zero shutter Portrait mode. No Rainbow effect in HDR+ mode if this is selected, but noise is encreased if isn't used in place where you don't have a good light source!

-Custom White Balance:

You can lower greens, or whatever colour you want (This would affect HDR+ ONLY). Adjust it accordingly to your taste!
