Hi Paul,

Have you tried Silverfast HDR? It is just like SF Ai except that it is used for imported images. It works well, though here again you must do a bit of tweaking of each image since the negative "profiles" are based on "average" exposures and SF's database doesn't include all emulsions. The nice thing about HDR is that it works with any scanner output. I have also had success in Photoshop by simply inverting the image and correcting for the R, G, and B masks in Levels. The fine tuning is done in Curves and Hue/Saturation. This is equivalent to what SF does.

Why are you using a camera for this?

Good luck,

Mike Strickler

Hi All,

I am scanning SF negatives with a digital camera (...) and I am looking
for a profile that would allow soft proofing the positive values of a
color negative while working on it. Is there such thing?


Or perhaps: would you know of a plugin filter for Photoshop that allows
shifting the RGB channels to remove the color mask of negatives while
inverting the image? I have tried SilverFast Negafix, but since the film
profiles and automated process does not work for me on imported images
and has to be done manually anyway (could be better with direct scans),
I am looking for something straightforward and basic that would do just
that in Photoshop, ideally with the possibility of saving presets. It
seems that the level tool of Photoshop isn't particularly good for that
or maybe I need more understanding. Any suggestion welcome!
