I do not have much knowledge in RAW image and doing some tests to understand it better.
The ASObjC script ask for RAW Image ex. HEIC
There you could change parameters. I have not include every parameter option in his example.
And save the output to tiff file on the desktop.
Any input or thoughts about RAW image is always welcome or your solution in ASOBjC.
use AppleScript version "2.4" -- Yosemite (10.10) or later
use framework "Foundation"
use framework "CoreImage"
use scripting additions
