I know this list, and so I recently used the one with “large” and the latest version: “RTv4_Large”
I’m guessing you want to save a large-bitdepth TIFF for import in another program… ?? If so, RT_Large will work just fine for your intent.
Correct, I will use 16 bit uncompressed TIFFs as my digital negative (result of a focus stack), and for this I prefer industry standard profiles, even if they are copyrighted.
Now I see that I can “install” it on Mac OS for RT by just copy it to /Library/ColorSync/Profiles/Displays
It is not a good choice to use this path, because Mac OS saves display profiles there, and never output profiles for images. It would be preferable to use (~)/Library/Application Support/ColorSync/profiles directly.
- I wonder that RT uses ProPhoto as working space but by default does not support it as output by default?
- Wouldn’t it be better to provide ProPhoto as default output for 16 bit TIFFs since no additional conversion is needed from working space?
