get the distribution of focal lengths used in your photos
February 22nd, 2008 by Lawrence David
it’s unfortunate, but exposureplot doesn’t run for the mac. don’t fear though — if you’d like to find the distribution of focal lengths you use in your photos, all you need to do is the following:
1) install jhead. if you’ve got http://www.macports.org/ installed, it’s as easy as:
>> sudo port install jhead
2)  love unix. navigate in the terminal over to the directory with your jpegs and run:
 >> find ./ -name “*.JPG” | xargs jhead | grep “mm” | awk {‘print $4′} | sed ‘s/mm//’
