Hi,
Bernard has a point. It has been demonstrated earlier by some Capture One users that using profiles for the IQ350 (I think) with Nikon D800 images yielded better colour than C1-s profiles for Nikon D800.
It may be that Phase One is making better profiles for the IQ-series than for Sony for instance.
Making own colour profiles for Capture One is a bit tricky, as they use different math from conventional profiles.
But, Anders Torger has found a way to generate ICC colour profiles for Capture One in his tools DCamProf (free and open source) and Lumariver Profile Designer.
I can try to generate an ICC profile for C1 for the A7rIII based on test images from ImagingResource in the weekend. I never tried it as I am Lightroom user.
But, such a profile may or may not get IQ3100 MP and Sony A7rIII closer. It depends on weather or not they use a similar CFA design. Also, even if the profiles would yield similar results, chance may be that they would not have a Capture One kind rendition.
For some reason I did a comparison comparing three cameras I have at home.
- Phase One P45+ back, known for tricky colour.
- Sony Alpha 900, same generation as P45+ but regarded by some experts (TheSuede and Iliah Borg) to have the best rendition of any commercially available camera.
- Sony A7rII, what I am mostly using now.
I enclose the result. There are four images. Top row is P45+, with two different tone curves. Bottom row is Sony A7rII on the left and Sony Alpha 900 on the right. Note the black boxes on the lime fruits. These were measured with a spectrometer. The limes in the front and the rear and the red pepper has boxes painted in with measured colours. These areas are close but outside the red boxes.
Would be interesting to hear your opinion on how these colours differ.
Best regards
Erik
P1 means... Phase One - or is there some other profile makes confusingly named P1?
I am using Capture One's own Sony profiles.
