I have now played with three different profiles using NegaFix. I am delighted with the profile for Konica Impresa 50. No lab has ever done well with this film. Cheers!

Fuji Superia Reala and Kodak Max 400 films come out too saturated for me and a little skewed to red. I can fix the skewing with the curves tool. Is there a way to decrease the saturation level in the profile-editing dialogue?

I'm not all that sure how to decrease saturation using SF's regular editing tools.

Thanks for any help.

NegaFix profile editing / reducing saturation

Currently there is no provision to change saturation inside a NegaFix profile. We have selective colour correction as a general feature in SilverFast, but it is a good idea, that I will gladly put on our feature list for a future implementation.

With SilverFast's Selective Colour Correction you can easily reduce the saturation for the primary (RGB) and secondary (CMY) colours. The easiest way is to use the HSL controls on the lower right in the SilverFast Selective Colour Correction dialog. Follow these steps:

1. Open the SCC dialog
2. Click on the colour you want to reduce saturation of (the colour will be selected).
3. Click several times on the lower pointer (triangle) of the S-control(saturation) until you see the effect.

You will see the effect immediately on the preview. Here is a link to show the dialog and the effect (here colour hue has been changed): https://www.silverfast.com/silverfast/se ... cc/en.html
Finally you can save the "reduced saturation" setting inside the SCC dialog.



Thank you for your contribution!

Thanks for responding about the saturation issue.

I've worked quite a bit more with NegaFix and have a suggestion on the Auto Tolerance tool in the NegaFix expert dialogue. In general, I find this tool to be visually counter-intuitive. It appears to carry over from one scan to the next. I can only verify this by clicking the slider (not dragging or changing it, just clicking it) and the three histograms change. Then drag the slider to the right and all the way to the back again to the left and one can see that the histogram is different from what it was before clicking the slider or otherwise touching it.

Do the auto tolerance values indeed carry over from the previous session? If so, why not leave the slider in the same position as the previous session as indication of this?

Thanks,
