Hello again RT forum,
I converted a Canon CR2 RAW to 16-bit TIFF using RT Queue with RTv4-Medium output profile with Rendering intent “relative colorimetric”. The files are here. (The image is part of a focus stack).
filebin link, as an alternative.
I get “Rendering Intent : Perceptual” as a tag in the TIFF file. Should this be “Rendering Intent : Relative Colorimetric”, or similar? Does this matter for a printer receiving the TIFF file?
Command: exiftool _Y8A8348-AdobeRGB.tif | grep Rendering
Result: Rendering Intent : Perceptual
Command: identify _Y8A8348-AdobeRGB.tif displays as:
_Y8A8348-AdobeRGB.tif TIFF 4492x6732 4492x6732+0+0 16-bit sRGB 173.045MiB 0.000u 0:00.000.
This the Imagemagick command identify. I wonder why identify outputs “sRGB”? (This is ultimately a question to Imagemagick developers).
identify -verbose _Y8A8348-AdobeRGB.tif | grep Colorspace
Why is “Colorspace” set to “sRGB” in RT TIFF output when I pick RTv4_medium (AdobeRGB) as output profile?
There are hundreds of lines of data from identify -verbose and exiftool. Honestly, I do not know if the output above matters at all. Perhaps my 16-bit tiff file renders perfectly when printed at the printing company and tags quoted are irrelevant? I do not know.
