Hi Ray,
Another technical but enjoyable post.
I'm not really sure how you measured the SNR mean signal / sd, but if I use the formula of
signal / noise (max histogram value / FireCapture noise estimate) would this work?
For example a histogram of 66 and noise estimate of 5 would give a SNR of 13.2
Also, would it be better to have the same exposure and gain settings and adjust the light source distance so they have the same histogram value?
