This really has turned my photos to the better. I had been using an old light meter that has lost its accuracy resulting in terrible dark negatives. This app was well worth the small cost.

I am really pleased with this app. Where my Canon EOS 5D MarkIII tends to max up the ISO when set on Auto, filling my shots with noise, this app allows me to set more correct values, using a more correct ISO. I am a hobby photographer, learning as I go, and this app helps alot!!
