I thought of opening a thread for CStark's Camera PX specific for the Pixel 3a, for settings, samples, comparing photos and for those who might not know it

Here are some settings recommended:
I am using the following settings on my 3a and PXv4.5. The result has been incredible. I always use it with the HDR+ Enhanced enabled.


ADVANCED:
HDR+ control: On

PX MOD SETTINGS:
Synthetic Fill Flash: Off
Disable Focus Tracking: Off
Disable Motion Photos: On
Non-ZSL Frame Count: Default
Maximum Zoom Level: Default
Super Res Zoom Always On: Yes
Force Sabre Merge: Off
DCI-P3 Color Space: On
Portrait HDR+ Enhanced: Off
AI AWB for ZSL: Off
AI AWB for HDR+ Enhanced: On
AI AWB for Night Sight: On

LIB PATCHER:
Tone Curve: On (with default and stock settings)
Shadows Point: 0.33 (Default)
Highlight Points: 0.33 (Default)
Shadows (Lower Curve Half): -6 (Shadows Stock)
Highlights (Upper Curve Half): 15 (Highlights Stock)

Force System Noise Model: Off
Disable Dehaze: Off
Sharpness: 0
Saturation: 1.5
Global Luma Denoise: 1.0 Default
Global Chroma Denoise: 1.0 Default

WAVELET LUMA DENOISE LEVELS
Level 1 (Fine Details): 0.375
Level 2 (Rough Surfaces): 0.375
Level 3 (Edges): 0.375
Level 4 (Smooth Surfaces): 0.5
WAVELET CHROMA (Low Frequency) DENOISE LEVELS
Level 1 (Fine Details): 0.375
Level 2 (Rough Surfaces): 0.375
Level 3 (Edges): 0.375
Level 4 (Smooth Surfaces): 0.5
WAVELET CHROMA (High Frequency) DENOISE LEVELS
Level 1 (Fine Details): 0.375
Level 2 (Rough Surfaces): 0.375
Level 3 (Edges): 0.375
Level 4 (Smooth Surfaces): 0.5

Is an adaptation of the settings that the @Gnaius posted here previously. Tell us how these settings work for you.

-> Do you have any other setting suggestions? Or any samples comparing Camera PX vs Stock Google Camera?

Using PXv4.3, but they should be quite similar.
Here are some of my settings:

Face shape correction disabled
Synthetic fill flash disabled
Super res always on disabled
Force sabre off
AI AWB on for everything (all 3 modes)
Lib patcher enabled
Global luma denoise 0.75
Tone curve on
Shadows -2
Highlights 17

The rest are mostly set to their defaults.

Now testing PXv8.1 and quite pleased with the results so far.
Only change from default is 'Google AWB' always on.
I personally prefer AI AWB as I care more about skin tones and "memory colours" than actual colour temperature.

So you say "AI awb off" is more accurate to reality? Interesting...

Not always, but often.
Actual colour temperature is usually somewhere in the middle.
I wish there was an option to control "AI AWB amount" rather than it just being an on/off switch.

What the AI is doing (for instance) is "thinking": This is a wall, walls are white, I'll adjust the white balance to match that.
In reality, some walls are actually yellow...

I leave it on because I found that it's very good at cancelling unflattering colour casts from artificial light sources such as orange'ish street lights.
The end result may be a less faithful recreation of the actual scene, but a better looking photo that is more similar to how we remember it, as our brain also has a tendency to subliminally "cancel" such colour casts in retrospect.

HDR enhanced always on needs still fotos which is not common always , if there is motion in what you capture results are blurry

Cstark has stopped developing his Pixel GCam but we have some news:

New update from MWP:

- Gcam_8.2.204_V1.1_MWP

Changes:

1. Enable face detection
2. Enable focus tracking on video mode ( Thanks cstrak27 )
3. Added JPG quality options ( Thanks PZD )
4. Added DCI-P3 color gamut options
5. Added Pixel 5 AWB ( Thanks Arnova8G2 & Rakin )
6. Added new paramenter on Rampatcher
7. Reduce saturation on my xHDR lib by default
8. Removed Dynamic depth options ( still unstable ), use the "HDR style / model" instead

---

Nikita also released a new update and it mentions Pixels ("Optimized GCam for Google Pixel devices").

I don't know how well it works and it's based on GCam 8.1 (not 8.2, like MWP's), but here's the link in case someone wants to test:

- NGCam_8.1.101-v1.2-fix

In MWP's GCam there are many parameters under "advanced" .

Interesting settings:
HDR+ style/model,
Ram Patcher,
MWP custom Lib HDR lib (red color),
Custom AWB,
Astro max exposure time

Will work a bit with this one, any setup recommendations are welcome.
