I've been messing with #infrared #photography using #termux #dcraw & #imagemagick  to process RAW files without needing a computer. There are examples, instructions & the scripts, in mobile friendly chunks, on my #selfhosted website, & the basics are on github too (https://github.com/Linecutterx/PhotoScript) More examples at https://www.macklin.co/infrared-photography-0/
