Conventional wisdom say that P45+ must be used Capture One. Personally I have a very strong preference for LR6. The one thing I do is that I use my own camera profiles for Lightroom, I have done that from day zero I had the P45+.
A few months ago I started using DCamProf, a tool developed by Anders Torger, with Lightroom.
Here are some screendumps from images processed in Capture One and Lightroom. Both pretty much basically processed.
- Color profiles: Daylight in C1 and DcamProf in LR6
- Highlight compression: HDR highlight slider in C1 and "higlights" in LR6
- Shadows: HDR shadows slider in C1 and shadows slider in LR6
- Colour profiles: Daylight in C1 DCamProf in LR6
- WB, white balance on same spot on both
- Sharpening: C1 defaults and my own default for P45+ in LR6
Results (C1 left LR right):
The "raw" file: http://echophoto.dnsalias.net/ekr/Ar...S/CF045436.IIQ
The DCP profile used is here (hopefully the right one): http://echophoto.dnsalias.net/ekr/Ar.../P45+_dual.dcp
So, what do I see? In these cases I actually prefer the results from Lightroom. That has obviously a lot to do with bias, I am a long time Lightroom user.
Anders Torger has done a great job with DCamProf, that effort should be applauded. DCamProf can generate profiles for Capture One, even if C1 is more tricky.
I have found that C1 does often a somewhat better job on colour aliasing than Lightroom. But, aliasing is not a great problem in many images, as resolution is often limited by workflow.
The results here reflect my experience with Lightroom (plenty) and with C1 (little), but both are very basic conversions.
