@spacemanspiffy ...and this is how it looked straight out of old Millipixels. Some improvements are in the kernel driver though - these aren't so easy to before-after - but most come from how the DNG file is developed.

@spacemanspiffy This one was from glowup because that was the most convenient option I had available on that phone right there. This is what you get when using my recent GPU ISP code - and yes, it is much better than what was there in Millipixels so far 😜

@pavel @martijnbraam @linmob You would need a more rigorous setup to actually see that non-linearity, what's here is still more of an artifact from averaging bunch of pixels. When you take just a single one, it's below the noise floor.

@pavel @martijnbraam @linmob Same thing, but brighter.

While there will be some tiny non-linearity if you look really close (there are no perfect sensors after all), it's absolutely nowhere even close to 5% and not really something you have to concern yourself with for photography :P

@pavel @martijnbraam @linmob No, that's clipping. My light source was 5% too bright, so you can see that it stays linear up until it clips.

@pavel @martijnbraam @linmob When you take only a few pixels from the center (with G channel clipped at the very top):

@pavel @martijnbraam @linmob After fixing Megapixels' tool, the result is linear up until the image starts clipping (at around 0.6 in this case). Since that tool averages the values across the whole frame, what you're seeing above that is lens shading.

@pavel @martijnbraam @linmob I was looking at these results some time ago and they turned out to be nothing but clipped data and lack of data pedestal handling.

@pavel @martijnbraam @linmob What you get from the sensor is already linear.

@linmob @ati1 Millipixels does audio in a completely broken way that has no chance to ever sync correctly, but there should be no hissing or artifacts there (other than a short pop at the beginning of recording). Does that happen with audio recorders as well?

@ati1 @linmob https://source.puri.sm/-/snippets/1223 can record video indefinitely with audio perfectly synced (see my recent posts at #shotonlibrem5)

@devrtz There is one - you don't see it? Not very detailed, but ultimately it's just a phone video of a live gig like any other: blinking lights, people with instruments on stage and dark silhouettes of audience's heads at the bottom 😂
