I'm building Deptheos (https://github.com/ryanmitts/deptheos), a photography/macro focus stacking program.

It works on MacOS, built with Swift and Metal. My goal is to make a super fast, and free, focus stacking program. I provided a notarized MacOS DMG for the initial release, but if built yourself, it will run on an M4/M5 series iPad Pro as well.

The core ability I wanted was to support RAW files as inputs, with DNG files as outputs. This is done using either LibRaw, or Adobe DNG Converter (runtime options).

I have been really into macro photography the last couple years, and have been slowly working on trying to build my own program to handle the focus stacking.

Very cool! Do you know Thomas Shahan's work? He once contributed his woodcut artwork to a videogame, so he does seem very technically curious. I bet he'd be interested in trying something like this out with his own work and providing feedback...
