As I like to use non-standard raw developers (rawtherapee for example) I'd like to extract a DCP profile for an old Hasselblad back, a CF-22. I could generate my own profile, but I'd like to have the "factory default" as reference.
As far as I know Hasselblad don't have icc/dcp profiles on the side like most, but instead have the color profile embedded in their proprietary 3FR file format. Lightroom nowadays should support Hasselblad color, so what I do is to convert the native 3FR to DNG with Adobe DNG converter, and then use "DCPtool" (a free command line tool) to exctract the embedded DCP color profile from the DNG file, which I then can use in my raw converter of choice.
This works, but I get only a matrix profile (called "Hasselblad 22-Uncoated"), and I was expecting something with curves. It could be that this old back is only supported with matrix, I don't know, or I'm doing something wrong. I would have tried it with a Hasselblad file of some more modern back but I don't have one laying around, and as usual raw sample files are impossible to find on the net.
I've noted that when exporting from Phocus to DNG no DCP profile is included, just a basic matrix stored in the standard Exif fields.
