Probably a total noob question but, when you scan a negative does the scanner itself process it into a useable (in colour) image or do you load the scanned file of the negative into photoshop and do it yourself?
As Samuel said, scanners that can cope with negatives usually come with scanning software. My plustek came with two packages, a cheap Windows one that I've forgotten and didn't install, and Silverfast SE Plus. That is a beast, completely unintuitive, but more or less learnable. Others swear by Vuescan, which is considerably cheaper and probably updated better. I gather that Epsons come with their own software.
Slides and black and white are easy. Colour negatives are the problem because of the orange masks (is that the right word?), which are different for all films (AFAICS), and even between different versions of the same film (eg Kodak Gold went through many versions with slightly different masks over the years). Both Silverfast and Vuescan have "presets" that are supposed to correct the inverted scan for particular negtive films. The trouble is, they don't have all the films in their presets (at least, for the 35 year old films I started scanning), and many old negatives don't give you much of a clue. I had a problem recently with some Fuji C200 negatives; I couldn't get the colour right. Someone here helped take one of my negatives and run it through ColorPerfect, and the result was excellent. The trouble was, I had to send him a linear TIFF which started at 45 MB and came back over 100 MB! I can't run ColorPerfect myself as I don't have Photoshop and don't want to buy it.
So for the moment I'm making sure I get all my colour negatives scanned at development time, and I'm also choosing colour negative film for which I have a preset. Not ideal, but it'll do!
You'd think the scanner software suppiers would exploit communities like TP by providing simple means of importing presets that others have researched, but AFAICS that isn't the case. :bang:
