Hi there,
Haven't had much time to really engage in any photography lately, but I have been noodling along on a side project that is looking at ways of extending what you can do with a handheld camera. If you take a series of photos in burst mode, you can register specific points in these images, then add the transformed images together. You end up with a controlled focal plane passing through the selected points where everything nearby is sharp, and everything further away becomes approximately defocused.
This synthetic aperture process can let you simulate a larger aperture, a longer exposure and also allows you to reduce noise or improve dynamic range. I've been working a little bit on some software that makes this possible, there's an example below synthesised from ~20 consecutive frames.
I'm hoping to turn this into a usable tool for everyone to have a play with or find some use from. More to come later.
