#It8 target vs. Patch#
The IT8 calibration is performed using an IT8 target (which is standard compliant) and a reference file with values for every color patch in your target. There are few things you should consider. Direct experience would be very valuable. I am looking for ideas what possibly could be wrong. As soon as I take more demanding slide with higher contrast the situation is even worse, especially with colors that contain some red (read warm) - in particular faces, red sofas. strong reddish cast to the wooden door (FAR from what the slide shows)Īfter following adjustments the scan is closer to reality (the wood is a bit too yellow): notice the greenish cast in the upper left Scan without any adjustments (slightly brightened with Levels) Also note that the preview looked the same as the final scan - I should have no miss-mach of profiles here (hopefully). P lease note that apart from calibration I did not apply any corrections with the scanner software. So some success is there, but it is not the whole story yet. I did try to scan the slide shown above - the overall magenta cast is much less, but the problem with red color remained. Below is a crop from a 6圆 slide - Provia 400X taken in shade in Alhambra, Spain. For testing I chose a less dramatic slide - one with neither too strong shadows or highlights or color saturation - to first see whether the "easy" scans will come out properly (or close to that). I calibrated the scanner againts all IT8 targets (4) to have calibration for practically any Fuji slide films. So I got a set of calibration IT8 targets from Wolf Faust - together with the data files. (scan of Velvia100, ektachrome IT8 target used for calibration)Īfter some discussions over at LFF I understood that to scan Fuji slides with calibration made with Ektachrome is not a good idea as the base has different color. However - using the produced calibration profile with Fuji slide films (which I use nearly exclusively) produced scans that had very strong Magenta casts in shadows and blown-away reds (when strong)

The calibration process is simple and after calibration the scan of the calibration slide looks fine: Namely - what I try to scan slides I get problem with strong color casts (towards red/magenta in shadows) and often reds going beyond the color gamut.įirst I had only Ektachrome IT8 target that came with the SilverFast Studio version I have. After longer time - but with still the same problem.
