I am taking over sampled images with a CMOS chip. I want to do software binning 2x2 but adding pixels instead of averaging. I am starting with a 16bit integer image and I want to end with a 32bit integer image that would basically have a lot of room at the higher end of the histogram. creating a HDR image. It seems as i do this in pixinsight using pixmath. It seems because PixInsight turns everything into a 32bit floating point, its does not seem to give me the results I'm looking for. Any advice would be helpful.
