Here’s a final (probably) version of the script with some niceties added and a little added functionality. I found out that you with termux-storage-get, you can access the SD card or external OTG storage. For me, this means I could process .orf raw files from my em10ii directly from an OTG card reader plugged into the phone. I realized that I could unlock this potential with a couple of code tweaks, and it could become a pretty powerful mobile photo studio to go from camera raw to processed JPEG, and then upload to social media with your phone…
So I updated to be able to add any raw file extension. I also added code to make and clean up the necessary temp files for the copied raw and hald-CLUT files. And some useful text is written to the terminal as you proceed through the steps. I will write up a brief tutorial and some install instructions, and then make a pull request to add it to the scripts git repository. I’ll include a sample raw and hald-CLUT or two…
