I recently discovered a program called ExposurePlot, for Windows, that allows me to analyze the exposure settings in my pictures. It gives information that I consider very interesting - for example, I didn't realize that around 70% of the pictures I analyzed were taken at the widest focal length I have on my Rebel XT, 18mm! Do you guys know if there is a similar program available for OSX? It would be ideal if it integrates with iPhoto. I only have a few pictures in my (work) Windows laptop, where I installed the program.
