Was your IT8.7 target a transparency, or did you scan a reflected target ?
Does the Epson Scan software allow profiling with an IT8.7 target ?
Silverfast scanning software allows calibration via a target, according to http://www.filmscanner.info/en/Scannerkalibrierung.html
Transparency (Ektachrome)
No. I've got Monaco EZ Color shipped with my scanner, but the scan was not profiled for this particular purpose. It was clean, linear scan.
It does. And when I compared (http://www.iccview.de/) color space of profiles made by EZ Color and Silverfast, I stopped using SilverFast calibration.
I don't speak German, but apparently that site allows you to compare ICC profiles. What difference did you see please ?
From what I can tell, the Monaco EZColor product is no longer sold. Aside from Silverfast, are there other tools available for calibrating Epson flatbeds ?
From memory, Silverfast does not allow creating IT8 targets for different emulsions. They only allow a generic profile. If that's right, it's a huge minus. The profile needed for, say, Velvia 50 is quite different from one needed for Ektachrome. When scanning slides, I use as unprocessed a scan as possible. When bringing the file into photoshop, I apply the proper IT8 profile and then convert to the editing space. On Wolf Faust's recommendation, I used Lprof to make the profiles.

Are these profiles mainly useful for overcoming the irregular color casts of various film stocks ?
I am interested in B&W linearization: getting a linear scan of an already linear Stouffer step-wedge.
Yes, that's right.

It depends on quality of light source of the scanner.
I've got different IT8.7 targets and scanned on 2 scanners. The results are here: http://jaz99.blogspot.com/2016/01/me...-scanners.html
Ken,
Various calibrated colour transparencies available from Wolf Faust at Coloraid.de I have the 4x5 Fuji Velvia and Astia ones. You buy for the film stock you need to scan.
Extremely easy to calibrate your v700 with professional Vuescan because Vuescan has a special routine that detects the target.
Simply buy the target for your film and Vuescan and you're done. Only works on Windows / Mac though I think.
Wolf is a very competent and professional person. The product is exceptional.
jaZ99 - I'm using Vuescan Pro and have done so for a decade. I mentioned Epson Scan in my post as I have it installed also but don't use it. I haven't paid for a 'pro' version I just have a version that came with the scanner.
:-)
Hey Peter !
Can I ask if you are using LPROF with Vuescan on Linux ?
I haven't looked for a long while but I would like to be able to scan with a calibrated monitor and calibrated scanner on Linux if I could. I've just loaded the latest nightly build of GIMP with its increased bit depth but it crashed on my first try ...
TIA
