[Closed] Convert a color film negative to positive digital image
Posted: Sun May 13, 2018 9:20 pm
Looking for a simple process or feature to convert an image of color film negative to a digital positive .
I have a way to directly copy 35mm color slides (positives) as very high quality digital images using a DSLR camera and Nikkor macros lens . Works great. It's so good you can improve the image like it was an original real world scene... adjust color , exposure value , even use the camera's built in HDR to balance shadows and highlights better than original slide film could expose for. So my positive-to- positive film to digital method works very well. I can do 200 - 300 slides in an afternoon , ten to twenty times faster than scanning them
Now I want to rephotograph 35mm Color Negatives in large quantites as well. Of course you end up with a " positive" image of a color negative, which is orange... orange... orange. That's how color negative film works. I would like a one-click Filter (or something )in Graphic Converter that will remove the orange mask and invert the values to restore the image to a generic positive image , for further editing. Just like printing it in a darkroom.
Even better would be a way to do a finer conversion based on the brand or characteristics of the emulsion that was being photographed... the orange mask of Kodak Gold ( consumer) , Kodak Ektacolor (pro) , Fujicolor , Agfacolor etc were all slightly different. A filtration setting for a particular film emulsion to invert the image more precisely would be a godsend. I have tens of thousands of color negatives , and scanning a color neg is a royal pain and very time consuming.
I think direct conversion would be very useful.
