[LG G6 Guides, News, & Discussion] vitoski:
In the latest version ZSL works only with Pixel Camera Configs and only if HDR is set to Auto.

A couple of facts and comments for those who are interested... in reading:)

During the last couple of months I spent a lot of time on testing almost all of the Google Camera versions released by BSG. I have also been following the original thread on 4pda forum where BSG publishes new versions and people are discussing various settings, combinations and share photos.

After all that time I came to the following conclusions:

Camera Mode / Model

# Pixel family (Pixel 2016, Pixel 2XL, Pixel, Pixel 2017 etc.) - it works quite well on our LG G6, BUT only in a good light conditions. If the scene you are shooting gets darker (equals less light for the sensor) it starts to show pink/purple/bluish tint. So if you take a picture in a room/building with bulbs turned on, the photos will have unnatural colors. This happens regardless of the selected Camera Profile.

# Nexus family (Nexus 5X, Nexus 6, Nexus 6P) - all of these modes work fine with LG G6 in both good and bad light conditions - this means they give close to natural colors in both situations.

Camera Profile / Config Camera HDR+

# ZSL (Zero Shutter Lag) profiles - they are meant for quick shoots and work only in HDR+ Auto (HDR+ On - in those versions where we have HDR+ Enhanced settings). So in practice the GCam should snap the photo right after you press on the shutter button (without any delay). Profiles with ZSL worked fine mostly in older versions of GCam (prior to 5.1.016 - all variants). In the latest version (5.1.0.16), only Pixel profiles work with ZSL, but they suffer from autofocus after it was manually set on a specific element.

# no ZSL (Zero Shutter Lag) profiles - there will be lag introduced between pressing the shutter and taking the photo regardless of the HDR+ settings (Auto/On, Enhanced).

HDR+ parameters:

# Default - this seems to be equal to 'Medium', at least by judging from the speed of taking photos when compared with 'Medium' level.

# Medium - this is the fastest mode for taking pictures in low light, but gives an average level of details and noise.

...

# Super High - the slowest mode, which introduce quite a significant delay before you can take another picture. However, this gives the best level of details and less noise comparing the other settings. Keep in mind that you need to hold your camera steady! Therefore, if you plan to shoot from hand it might not be the best HDR+ parameters level, especially in low light conditions.

Developer Options

# Burst mode - enable 'camera.diet_burst' (works both in ZSL and noZSL profiles, as well as with HDR+ Auto/On and Enhanced). Simply hold the shutter button for a little longer.

# Face recognition - enable camera.faceboxes

Combinations

As you are aware, BSG allows to select 'Model', 'Config Camera' and 'HDR+parameters' in his version of Google Camera. This means you can mix how the final photo will be processed - i.e. choosing Nexus 6 (for good color reproduction) as Model and Pixel 2017 HDR+ ZSL for 'Config Camera' you tell GCam to mix the processing algorithms while finalizing the photo.

In my opinion (very subjective) it is better to use the same "family" and in fact this is something that was giving me the best results so far. I used to use Nexus 6 (Model) with Nexus 2016 Tunning (Config Camera) and Very High (HDR+ parameters). Unfortunately the latest version of GCam broke the ZSL on Nexus like profiles... so if ZSL is something you are after, select one of the Pixel configs.

To make the long story short, in my opinion, it

is not worth to use

any of the

Pixel Models

, as they simply break color reproduction. While it is not visible or barely visible in good light conditions, it is obvious and easily noticeable in low light conditions - especially if you shoot with the highest possible HDR+ option (On/Enhanced - depending on the GCam version).

In terms of Camera Config - for me either the Nexus 6 or Nexus 6P were giving the best level of details comparing to any Pixel Config on the same level of HDR+ parameters (Very High and/or Super High).

One more thing!

From what I have observed and proved by tests, we cannot relay on comments and suggestions from the original thread (4pda). The original topic is focused on Xiaomi Mi5S, which has a different sensor than LG G6. A good example is the Camera Model, people with Xiaomi Mi5S recommend to use Pixel 2016/2017 models as this gives them the best results (in low light!). No purple/bluish tint, good level of details etc.

That being said, we should come up with our own combinations for LG G6.

Final ask!

If there is anyone who speaks Russian and could let BSG know that ZSL doesn't work with none of the Nexus like configs that would be awesome. Personally, I do not speak Russian, hence I have no way of contacting the developer.
