Add autofocus brackting
As written by @JassMan23 in the #146 issue:
Another USP (which I once thought of patenting but I hate patents) is autofocus bracketing. I believe there was once a camera which had 3 transparent sensors so that they all took the same picture but each was in focus for a different part of the scene. Clever software then allowed you select focus to be any distance you wanted. This could be sort of emulated by taking the same scene 3 times with different focus. Obviously not as good as the special camera because there is a chance of movement but would still be useful for post editing as you could have your model in focus and the background to simulate a small aperture since I don't think phone cameras have a variable aperture
