I use Linux and would like to know, if it is possible to query how much pics I made with ISO 80, ISO 100 a.s.o. My idea is to search for all original-pics with find and then pipe it to exiftool. One query could do an analysis which ISO I used, maybe I have to use sort and wc for it. The result should be like this e.g: 1300 pics with ISO 80, 4000 with ISO 100, a.s.o. It doesn't matter how the result is presented, I need the info only. If I can't do this with 1 query, please let me know, what comes closest.
