My understanding is that, though without embedding it, this option uses the
scanner profile as selected in your graphics program in transferring the
image to the graphics program, and the graphics program would than embed
it's default/preferred color space in the image if it embeds such spaces as

"Nearly imperceivable effects" are a large part of what makes a picture

Yes ... but it seems to me that list of profiles is particular to

so, then it should work for PS5 as

about 8 of them in my ColorSync folder.

I guess you will have to ask him exactly what he is using.
The discussion was about PhotoCD embedded profiles. Not standard
spaces, such as AdobeRGB. The "Transforms" you can download from
Kodak - ASFICT are profiles, used to open files formatted in PhotoCD
format. For opening files only. But

They are all different:
pcd4050e.pf for E6
pcd4050k.pf for K-14
pcdcnycc.pf for color negative

Richard,
From my reading of info on Vuescan, it does indeed use the PCD
colorspace, and I don't think any violation of anything is occurring.
The color space of PCD could easily include all of the film types you
speak of, regardless of a bias (filter) used during the scanning
process. Furth

This is rapidly treading way off topic. Into a discussion of what is

Depends on the Photoshop 6 Color Settings [Edit > Color Settings]. It should act as
