I just prepared a little test scene to compare the three setups:
- Graphene OS Stock Camera Version 45
- Gcam 8.4.3 Beta 4 by MWP + my low light config
- Original Gcam 8.6
Stock GOS cam is the softest with lowest contrast and broad noise across the image.
My version is much clearer, has some decent HDR, much lower noise and no serious filtering artifacts.
Stock Gcam has much deeper blacks and looks a little crisper due to stronger HDR. Too artificial for my personal taste.
GOS cam is partially blurry and loosing detail. Noise performance is mostly ok though.
My config boosts much more detail out of the image without looking too crisp. Noise performance is showing some artifacts in the upper area of this shot - I'm working on it.
Original Gcam is again a bit too boosted in texture and contrast. Noise performance is showing some artifacts, as well. However, since it has stronger black boost, the artifacts do not shine through that much. Raising the black level would probably equal what we can see in the middle image.
I'm still trying to improve the noise suppression a little. However, tweaking the one thing does usally come at the cost of degrading the other. The raw images of those tiny sensors are usually very noisy and low dynamic. That's why there's always a bottleneck at some point, even in bright sunlight.
Other than that I'm pretty happy with the results. I think my config hits just the middleground between too much contrast and HDR versus too blurry and washed out.
Let me know what you think.
