PM5 HCT No Extension.jpg - as for DCSG above
PM5 HCT Extended.jpg - as above, but highlights extended significantly
CoCa QP203 Gammamatrix WP 1.2.jpg - CoCa generated profile from QP203; Gamma+Matrix algorithm; White Point 1.2
Haven't thought this through into an essay so here are some points that have struck me:
- Silverfast's generic V700 profile yields very good colour. It does compress the contrast, however, which would need to be fixed to get a match. Mainly it's the highlights that get squished - instead of being bright and clear they are a little murky.
- There really isn't much between the PM5 and the CoCa profiles. I can get a good match fairly easily with either. PM5 seems to retain a little more detail in the highlights, but loses a nitpicking touch of absolute accuracy. I'm running with the CoCa profiles for now and will continue to do so unless they start presenting issues.
- note how massively the un-extended HCT profile clips. not an appropriate target for this work. it's great for photographic prints, of course.
- the extended HCT profile enters the realm of useability, but needs lots of contrast and colour work for a match. (this is actually how I started this kind of work last year, before trying the DCSG)
- for interest I included a CoCa profile generated from my QP203. Generic reference file. The Lab Clut algorithm gave awful results, but the Gamma+Matrix with a white point tweak seems to be OK. It's rather punchy and oversaturated, but it's not a horrible profile. Not bad for a $50 target and not-ideal reference data.
That's it for now.
