Ich hab ne schöne Sony α6000 Kamera geschenkt bekommen, und hab Lust fotographieren zu lernen.

Die Kamera macht #RAW Bilder und wandelt sie intern auch in gut aussehende #JPG um. Nur ist sie halt über 10 Jahre alt, entsprechend veraltet ist die Software (hab schnell auch alle Wireless-Funktionen ausgemacht ;D).

Möchte mir deswegen mit #dcraw und #GraphicsMagick einen Automatismus bauen, um die Raw Bilder selber schnell in moderne JPG umzuwandeln, die am besten auch kleiner sind als 7MB...

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

Are you serious about #photography on #Linux ?

Then you probably used #code derived from #dcraw . It's an amazing store of information about developing raw pictures.

But there's one problem.

It's write-only code. My mind goes blank when I read it.

Thankfully, someone started a readable library for raw files, called #libopenraw :

I ported Panasonic #decompression and made it possible to understand :D

(#Fedora plz package it)

If you like #ReverseEngineering , go ahead and take a look at #dcraw . It's one of the finest examples of write-only C code bases I've had the displeasure to learn from.

case 274: /* Orientation */
tiff_ifd[ifd].flip = "50132467"[get2() & 7]-'0';

I dig that #libopenraw is now fixing that. And not even because it's in #Rust. I can actually follow the code!
