I have been scanning film slides using Nikon Coolscan V calibrated with IT8 film slide targets (Velvia 50, 100, Provia 100) from Wolf Faust. I have also started digitizing film slides with DSLR camera on a copy stand and light table. Would you have any advice on a good workflow to profile raw files from digital camera using IT8 slides. Do you know of any way to create Adobe Camera RAW profiles that I could then directly assign to raw photo in ACR? For regular digital photos (not film reproduction) I have used successfully Color Checker Camera Calibration which can create a custom ACR profile from my Color Checker passport, but it does not allow the use of 3rd party film targets. I’m looking for a similar concept but one that works with film IT8 targets and hopefully allows me to stay in RAW workflow instead of intermediate TIFF files. If there’s not a way to create ACR profile, what would be the best next alternative? Take a photo, assign a neutral camera profile in ACR, export to TIFF and then profile as usual? I also own Color Perfect photoshop plugin for negatives – would the MakeTiff utility from that software help in any way to create linear TIFF from camera RAW file and then create a profile from that TIFF, in a similar way I produce profiles from Vuescan RAW TIFF with Nikon film scanner - see workflow below? My current method for profiling flatbed and film scanners is: Create RAW TIFF in Vuescan, open it in Photoshop, do not assign color profile, use levels to assign gamma (anywhere between 2.2-3.5), export to TIFF, run it through Rough Profiler, repeat cycle with different gamma assigned in PS to find result with lowest max and average error, check that black and white do not clip. E.g. for Velvia 100 on Nikon Coolscan V, my best results are with Vuescan master analog gain set to 1.5 and photoshop assigned levels gamma at 3.0. Thank you.
