Re: [Digital BW] Making b&w contact sheets on a flatbed scanner

2002-03-08 by Pics4U@en.com

A flat bed scanner utilizes reflected light and negatives/slides need the light 
to pass through them.  I don't see how you would get it to work unless you 
rigged up something of an overhead light on your scanner. 

I know you are going to think this rather dumb but it works.  Assuming you 
have your negs cut and in sheet type negative sleeves, tape them a sheet 
at a time to a window on a bright day. Then using your best macro lens 
simply photograph each sheet.  You won't get repro quality but good 
enough to look at on the computer and print out for referrence. I use my 
digital camera so it makes tweaking pretty easy.  

If you can get close enough to fill the frame, I'd trust the in-camera meter 
and then maybe fudge a stop for a test.

Of course you will have to invert in Photoshop but since they are B&W, at 
least you won't have the orange mask to deal with.
