Description

I've been wondering what are the differences between 12 bit and 8bit (highspeed mode) in Firecapture. Yesterday I was able to spend half an hour outside during the workday. I decided to dig into this matter. 

This is a comparison of 12 bit vs 8 bit. In both cases I recorded data for 60 seconds and then stacked different amount of frames. Here are data shown with best 5 % stacks. The upper row is inverted data and the bottom row is more normal processing.

I have my opinion on which I prefer, but how do you see it?
