CM Input Profile Keeps Changing Back To 'None'

Postby PixMan » Sun Mar 18, 2012 4:29 pm

I have just updated to the latest version of SilverFast (8.0.1r7). I am scanning negative film. When I updated I also deleted my old preferences as new ones are generated once restarted.

My issue is that SilverFast will not remember my choice of Input Profile (the one I created using the Monaco profiling software for my scanner) however many times I set it. If I set all the CMS preferences including this one, and then scan the image I have in the red frame, the input profile resets itself back to 'None' before I press Scan. This is the same whichever input profile I have chosen - they all reset to 'None' when the preferences box is closed.

Is it supposed to do this? It retained my choice when I was scanning slide film.

Also is there any way of stopping the navigator window from opening and popping out of the side list every time I select iSRD - it is just irritating to keep having to move it back and close it again.

Thanks

Yes it is correct, it is supposed to behave this way because you are scanning negatives. In this mode, the Color management is taken over by the NegaFix dialogue.

Thanks for letting me know. I had been scanning Fuji Pro 160S film but the NegaFix dialogue for this film changes the colours to look washed out and rather overexposed (even thought the negatives are correctly exposed). In the end I set the film type to its default of 'Other' and the 'Other' associated settings in the NegaFix dialogue box to get better colours. But why was this work round necessary? I'm finding that washed out colours similarly appear with the Kodak Ektar 100 profile (though other profiles are better)?

Also why does it change the exposure to -0.6 when some film types are selected (like these 2)? Is this normal too? The slides I have scanned are excellent but negative film scans aren't as good, and if slide film is discontinued in the next year or two (I hope it isn't but Kodak have discontinued theirs), my results will not be half as good with negative film!

Thanks.

This is not a workaround. Scanning negative films is not the same as slides. The reason is the orange mask of the film which has to be detected and removed first thing.
This task is performed by the NegaFix dialogue, then a film profile is applied to it, please bear in mind that there are some variables when scanning negatives and hence you have diverse sliders and controls to perform adjustments.

Thanks for this and I knew about the need to remove the orange base colour cast, it's just that the profile itself for Fuji Pro 160S and the one for Kodak Ektar make the colours look weak but other profiles in the NegaFix set up don't.

Is it right that is resets the exposure slider in the NegaFix dialogue box to -0.6 too as its default with these films?

Thanks.

Because of the many steps involved in the negative process is more complicated to reproduce accurate colors. You have many variables like film batch, production date, packing and storage conditions and time, scratches in the film surface, condition of the developing chemicals, temperature, and then the scanning process itself, hence orange masks are not always the same (even if they are from the same film type and batch) .

The NegaFix profiles are created using the finest calibration film stripes for every type of film. Such stripes are created under a completely controlled environment whereas that is rarely the case with the film stripes of common users, all variables mentioned above are simply out of the control chain, hence little color mismatches or inaccuracies can happen.

For this we recommend using the tolerance slider as well as the advanced controls in NegaFix which allow for more accurate adjustments.

No it is not right, you can set the slider to 0 or reset preferences of SilverFast using the service dialogue found at the welcome screen at SilverFast startup.

I have reset the preferences several times using the Service dialogue at start up, but it still chooses the -0.6 setting when I select the film emulsion in NegaFix with these films.

Hi Pixman

I see if I can reproduce the problem here. Please move the slider to 0 in the meantime.

Thanks

I also have this problem (Reflecta Proscan version). The exposure cursor is systematically set to -0.6 even before selecting any film type and after having reset the preferences. Is this a default setting for the Proscan 7200 ?

Yes that is the standard setting for that value.
