In APP, I retain the saturation adjustment but do not use any sharpening option- AFAIK, in APP the histogram stretch is independent of an unsharp mask.Drakkith said:Indeed, DDP does both a gamma stretch AND an unsharp mask, rendering any quantitative analysis basically impossible. At least for me.
As for your numbers from Fiji's analysis, I can't really make any sense out of them. All I did was choose a single pixel in my image for a quick analysis on. I also don't have a color camera to complicate things, just a monochrome camera with a filter wheel.
I can't make sense of the numbers, either. I don't think the Bayer filter greatly complicates the issue (since a 16-bit/ch image is created by a 2 x 2 average of 14-bit data), but using a single pixel for analysis goes against my original query.
