Digital BW, The Print

This might be a tad of topic but someone here may have the 
answer. I am scanning 2 1/4 with my epson 1600 using 
Silverfast Scan software. Silverfast gives great control over 
scanning chromes, and b/w, as long as I don't scan HiBit. But I'll 
be darned if I can get a good scan in HiBit from Silverfast. The 
scans are dark and difficult to adjust in PS. Yet scans from the 
Epson driver in HiBit (even with the crude controls) turn out much 
better. So much better that I must be doing something wrong but 
can't figure it out. Any ideas? 

Dave

Dave,

Hibit mode in the Silverfast software is actually a RAW file format. As such
you need to check box in the options that says something like "HDR OUTPUT".
This allows Silverfast to lighten up the image so that it is workable in
Photoshop or better yet Silverfast HDR.

the hi bit output from Silverfast is not gamma corrected. All the
information is there but to correct it in photoshop you need to do a levels
command to set b/w points (use auto with 0% clipping) and then  change the
gamma either using the centre slider in levels or by applying levels and
going into curves and fiddling with the midtones.

As someone else said it is possible to output gamma corrected 16-bit files
from Silverfast. You set this in options somewhere... with a check
box...would look it up for you but disk crash has taken out all my apps this
week.

It sounds like your Silverfast HiBit scans do not have gamma 
correction (easy to do) whereas your Epson HiBit scans do.  You 
should definitely check out Ian Lyons website and his Silverfast 
tutorials.  They're excellent and should answer you question.

Mike,

I figured it was something like that, but still can't find anything 
similar in the options. Where should I be looking? I am using SF 
5.1 on a mac.

Thanks for the input. I'll check out the tutorials and work this out.

FYI... I was using Silverfast 5.1xx something and I downloaded 
an upgrade to version 5.2. Big difference! 5.1 did not control 
gamma on HiBit scans like the Epson software did. Version 5.2 
does. Thanks for all the help.
