No use backlighting for slides?
When backlighting a standard flatbed as though for trying to copy slides
or negatives, I assume there is no point in this as the scan head in the bed underneath needs to sync the light coming from above somehow as into red, green and blue bursts that would only come from a plug-in head and not a light source held above? I ask this as I have a Canon CanoScan FB330P flatbed scanner and I have just tested a colour negative using a backlit source separated by a white plastic card diffuser and the result is a black and white copy. So, I assume it's get rid of this unit which has done well for some years and get one with a plug-in attachment that sits on top, time? Mine is not your usual scan method (for slides or prints) as I have short cut strips of Super 8mm film which are only of value historically and not worth splicing together, so I need to scan a strip in and chop it later in a paint package. |

Obviously, your method could never be optimal. However, I don't know why it came out b/w, with no semblence of color. Should have at least looked "orangeish". There are also lots of "home brew" lighting methods for top lighting a flat bed, but as you've pretty much already found, none are as good as one designed for the scanner that is designed to scan film. Also also, you'll get much more action at comp.periphs.scanners. This is pretty dead group here. MM Yes, it puzzled me too! I'd initially did a big run some months back with some old WWII negatives of my father's that were here for a short while so didn't think about colour problems. Then I try a colour negative, do a 'negative' in Paint Shop Pro and it's black and white. Even the source looks black and white so that gave me the clue that something was wrong. Many thanks for that. |
