Raw scanning

Raw scanning

2011-08-06 by Greg

For those who use Viewscan to scan negatives to raw files, how do you then do the inversion to positives.
The inbuilt Photoshop is just a linear inversion. Do you use a curve that is similar to the film sensitivity curves?

Cheers
Greg

Hi Greg:

I use Vuescan for my long obsolete Sapphir and a Dimage scan dual.

When you set up Vuescan for scanning B&W, you can tell it which brand  
of film it is, and pick  _some_ of the varieties in that brand.  
Vuescan then, I assume, applies the curve attached to your pick when  
it processes the file, and presents you with a positive finished image.

Perhaps if you ask Hamrick software you can get a more authoritative  
answer.

Vuescan can directly store the film into a RAW positive image. You
just have to select the RAW option in the output settings (I have the
french version: "RAW sauvegarde de film").

I work on the B&W negatives as a positive on screen. I set up my black
point, white point, set curves, and scan as a RAW and as a TIF. The RAW is
opened in LR and adjusted. I see no reason to work the scan as a negative.
The presets that were mentioned are developing presets; CI. That might not
mean much to you unless that is the way you originally worked with film. 

 

Keep the exposure based on not losing what you want to keep; shadows or
highlights.
