Re: ACV Files

2012-01-09 by fjulsing

Roy,

Looks like there's maybe more to it than I thought.
There are two versions of ACV files, 1 and 4. Version 1 is pre-photoshop 6.0 and version 4 is the version since PS6. Version 1 files differ from version 4 files.
Since Curvemeister supports PS5.5, it writes version 1 files and Mike is reluctant to change to version 4, which is perfectly understandable. PS6 and on reads version 1 and 4 and writes version 4.

QTR on the other hand reads version 4 grayscale. 
Would it be too much to ask to have QTR also read version 1 ACV files?

Thanks.


Frank
