IT8 standard unprofiled by s162216, on Flickr I am now using an external program called 'Scarse' to make a profile for my scanner (it gives an exposure dependent look up table (LUT) based profile which is a bit more advanced than the one vuescan generates) and you can clearly see from this how profiling makes a darastic difference: Afterwards all you need to do is set the white level after in photoshope etc. You can obviously change mulit-exposure, multi-pass etc, rotation etc off and on. Keep all options about colour and exposure constant and that way you'll always get a constant exposure as you use the same exposure value for any slide to get a constant correct colour values. Repeat until you no clipping is showing (or only a few tiny little pixels) and then adjust the grid over the patches and click 'profile scanner' under the 'profile' menu (thus generating the profile). Turn on 'lock exposure' on the 'input' tab and adjust the RGB exposure number up a bit then preview the target again, if any of the white patches on target are green (indicating overexposure clipping) then adjust the exposure value down a bit and preview again. Steve thats better but to get the profiling correct you need to lock down the exposure value and keep it constant for all scans: in the 'profile scanner' mode preview the IT8.7 target (with the exposure lock off) then go to the 'colour' tab, set 'colour balance' to 'none' and turn on 'pixel colours', that way it will show you where there is any clipping. Sadly I am no longer doing film (for personal matters) so my targets are not going to see any use (selling it here if anyone cares). I would not say some of the films in the set were useful to me - I don't have Agfa slides so that was of no use but Wolf's price was good enough at that time for me to justify it. Tim Parkin in his blog was experimenting with these targets and he thinks that although in theory it should not be different regardless of the film you use (as you are profiling the scanner response) but in practice there will be a difference between the spectrum of light that was used to put the target on the film and the one used in scanner (and the film response to that for each of the colours). Having profiled my velvia and ektachrome I also would say that I would now recommend to get a target on the film(s) you are going to profile because I did have subtle but important differences in colour appearance using Ektachrome on Velvia shots. I can confirm it does massive difference especially where tints are slight but very annoying. To profile both Velvia and Ektachrome slides. I ended up buying the S1 target (a combined box from Wolf's site) in the end.
