Do you use Apple Aperture 3? Do you want to find out what lens you use most? What apertures do you use the most? What shutter-speed? Does your shutter-speeds stay the same each month, or do you evolve? Do you use the full range of your zoom-lenses, or should you use fixed lenses?
No need to wonder.
Aperture Inspector
will analyze your aperture library and give you all the facts. With graphics. And tables. Amazing!
