Morning, Heath!

0n my Agfa T2500 duoscanner, I do scan negatives in the RGB positive
mode and then invert, because I found out by doing that you will get
every bit of information in the scan that is in the negative. You can't
do that if you scan a black and white negative as a negative, unless the
negative is a little on the flat side. A high contrast negative, with
lots of higlight and shadow detail is impossible to scan as a black and
white negative on that scanner.

On the Canon FS2720, It is much easier to get all the detail on a black
and white negative than with the Agfa.

I ususally just scan black and white negatives as B&W negatives.

The blue channel is the worst for noise and grain, and the green is the
best. Post sharpening is the most valuable thing you can do to enhance
the quality of a scan. If you do it just right, you can get more
sharpness out of a negative than you'd think you'd be able to get. 

If I have a very contrasty black and white neg in 35mm, I still do scan
it as a color RGB and invert. A sample of this type of image would be a
shot directly into the sun in the fog, where you still want to see the
suns disk as well as retain  a little shadow detail in some backlit
evergreens. This is the hardest type of scene to scan, and where you
definitely want to scan it in RGB mode and invert. Wouldn't hurt to have
a drum scanner for this type of negative!

Do you by any chance know if there is any new software for the FS 2700
Scanner? I'm still using the original version.

I don't do a lot of 35mm scans, so haven't been keeping up with the
latest. Of course if you compare the 4000 DPI scanner directly with the
FS 2700, the 4000 will win. But with careful upsampling in Genuine
Fractals, or the SI plugin that someone recently made available on these
lists, you surely can get professional quality 13x19 prints from that scanner!

I can't remember who posted that action plugin to resize images, but it
works like a charm, and indeed does appear to be better than either
genuine fractals or the photoshop bicubic method.

Thank you for posting it!!!
