Hey! I'm trying to evaluate how I use all my lenses. For instance I would like to know when do I shoot below 1/focal length below ISO 400 on my zoom to evaluate when I actually need IS. I know there are tools like exposure plot but I cannot choose to view a specialized data set.
I need is to consolidate all exif info from 50.000 raw files into one spreadsheet file and from there I can extract all the data I want.
Any good programs for this?
