I would like to obtain statistical data on a large collection of pictures (e.g. distribution with mean and/or median of ISO used, diaphragm, lens mm...), type of camera used. This software must be able to recognize jpg, RW2 and ORF files and run on Apple Macs (OSX). Years ago, I used "Photostats", but it seems this program has not been updated recently and it only recognizes Nikon, Canon and jpg files. Suggestions?
