scan B&W as neg...WHY?

scan B&W as neg...WHY?

2005-05-02 by Djon

In my journey to fine B&W from Nikon V-scanned B&W negs I've been
playing with an image that never printed well in 1975 using a fine
Durst and Agfa Brovira...Tmax (never liked that stuff). Important
personal image. 

So far I've gotten best results scanning as POSITIVE, then inverting,
filtering dust & scratches (PS7), applying light USM, increasing
contrast (the pos scan is very flat). Print QTRgui/2200.

I'm getting more life (midtone separation) in shadow-sides of faces
than I have so far when scanning as negative...the overall image
appears sharper, with less USM, because certain tones aren't muddled. 

Scanning B&W negs as pos is often suggested... helps with this
image...any idea WHY this works, if in your experience it does?

Hi; I too have a Nikon scanner, and scan as positives; this gives you 
all the information from the scan which you can then massage to your 
liking. If you scan as a negative, the software sets black point/ white 
point and contrast curve, and for a B&W neg it just doesn't work well. 
does a bit better for color negs though.

Thanks Steve..

It's "often suggested" but I never really believed it was true... I
thought I was off into urban-scanning-mythologyland...

Did Nikon mention it somewhere... or is this just a wonderful bit of
Internet wisdom?

This supposedly was important with the 8000 and is not necessary with the 9000.

Haven't tried it though.

Vuescan workflow....Re: scan B&W as neg...WHY?

2005-05-03 by Djon

neg>neg>pos seems distinctly better with V than neg>pos BUT I've just
tested Mendel's neg>pos workflow in Vuescan and done even
better...sharper even...per this photo.net thread:

It was actually a known flaw in the software, Nikon was trying hard 
to ignore it. About 2 years ago another list member (I believe Ernst 
Dinkle?) circulated a petition politely requesting they clean up 
their act; I guess if it's no longer neccessay with the 9000 they 
finally did something about it.

I've just tested Vuescan with some suggested settings...very
good...better than Nikon neg>neg>pos....somehow sharper as well as
perhaps better tonally...maybe the inversion loses something Vs
original TIFFs?

Interesting about the old news :-)
