Hi, I uploaded some Photos for comparison here: http://www.bilddateien.de/transfer/ From that it appears to me that jpg from camera and jpg from Nikon's ViewNX give the same, but smaller image size than the raw. Export from darktable equals the image size of the raw as reported from ViewNX.

I was trying to compare values in imported jpg and raw files and notice that when I exported both as jpg format they appear to be of differing size. JPG size ... 4752 x 3168 RAW size ... 4752 x 3158 Looking at the files in dt this difference is also seen. Is this a Canon camera 'feature' or is
