Hi,

I'm involved in a project where the main aim to scan cinema pictures,
so it will be possible to overlay the pictures with some graphics.\
The negative of the film is scanned seperatly with red, green and blue
light. The problem now is to reconstruct the picture (from the scanned
RGB data) with the original colors. This is a problem because the film
material react differently to different colors. Does anyone out there
know how to do the color correction after the scanning of the film
material (making it first of all possible to see the scanned result)?

Do you have any hint on papers or any suggestions, please reply here or
email to roxx@diku.dk.

Finn.

You may care to post this to rec.photo, and scan the newsgroup for Mike
Axeman from the Kodak Photo-CD group and someone from Interleaf who posted
recently and mail your query to them. Are you scanning negative or positive
material? The corection will also depend on film type used for output. including
type of film etc will help the answer
