B/W Negatives are Grainy

Postby djohnson » Fri Apr 28, 2006 5:15 pm

I am trying to scan black and white negatives using a Microtek ArtixScan 4000tf and SilverFast AI V6.4.3r9. I am doing a 4000dpi high res scan for archival purposes. The film is Kodak 5062 PX. The scans are coming out VERY grainy and VERY poor quality. I have tried all kinds of different settings with no luck. Are there any "magic" settings for this combination?? I have had good luck with doing color scanning on this setup, but the b/w isn't working. Can anyone PLEASE HELP??


Thanks!

djohnson,

If you are selecting black and white for your scans try using 48-bit Color. This will give you two additional channels of image information. In addition try using the Gain filter to smooth the images.

yes - as RAG says - use the 48 color all the time and disaturate it if u want pure grey.
whatch for the sharpening mask - make sure it is not wilde. u hae preview there. dont use the auto settings, surely not with the b/w films. here is the setting for b/w sharpening that i use as an example. but watch the movie of sharpening or read the relevant chapters to see how well u can control it.

What are the advantages of scanning Black and White Negatives in RGB over 16 Bit Grey Scale ?

Dear user,

Using 48 bit would allow you to keep any distinctive characteristic of the B&W film.
Most B&W films have a slight green or blue hue and this would bee preserved this way.
Also further editing might require RGB channels in some applications. Not all tools can work with a true greyscale image.

Kind regards,
Arne
