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.
