Optimum CS is a great app for finding the optimum depth of field for your images. It works on the iPhone and iPad and it's better than using depth of field tables. It's very simple to use and only cost £2.99 There is also a Pro version with more advanced facilities. Most depth of field tables and apps work using science that was developed for use with film and so are not as accurate.This app has been developed for digital and is more accurate. Just search Optimum CS in the App store search area on your phone to find it.
