Douglas Photo Calculator

By Douglas Software Free to try

Developer's Description

With this software you can calculate all those neat little things you were taught when learning photography... Quickly and without any pain. Enter the details of your objective (f number, length) and camera ("film format", or if you prefer, sensor size) and with it you'll get quickly and without further pain the angle of view and focus. You can also switch to hyper-focal distance to get the details you'll get in this case (again, like angle of view, image width and image height.) If you have ever dulled through a "classic" photography course you'll know how hard these details are to get unless you are very used to them. Entering the details is easy, all fields offering a large set of default/industry used values as well as offering a manual option (which is great, since this makes the app almost "future-proof".) You can choose among 5 languages (English, French, Italian, German and Spanish) as well as between metric (meters) and imperial (feet) units for the distances. You can even set your own circle of confusion value, which is something severely lacking among other similar applications.
