Very good app Not sure why those 1 and 2 stars, but clearly it has to do with misinterpretation of the functionality of the app. The app will NOT measure the parameters and tell you how to take perfect foto. It will tell you how to recalculate and fine tune your parameters based on those you entered. It does precisely what is described. You don't need book or excel tables to check the values. But if you know nothing about photography and don't know what you want to achieve, you will not find it useful.
Good app Does what is says on the tin, no fancy nonsense, and seems accurate. Alot of hard work has gone into this app and it shows, so good work.
Not enough cameras As per usual DSLR catered for micro 4/3 users go whistle
Very well thought out and excellent presentation. Handy and with the right information without becoming too complex even for very difficult situations. If you know what you're doing or care, this app nails it!
Pretty good This is a very good app to use. I like the DOF part of it more.
It's a very good app for reference of DSLR handling.
