This app is for photo geeks and I'm proud to be one. ;)
Very professional. Not for amateur like me. One should take a photography course to Know how to use it.
One of the best DoF calculators out there. It is simple and easy to use with a very clear UI. I suggest this app to my photography students.
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.
