Ken-
How much more resolution might you pick up if you did an 8x10 print instead of 
5x7?

Thanks,

> What is a scanned work print?  Scanning a print rather than the negative?

Correct.

The advantage are five-fold:

1. Recreates the gamma curve in a natural way that requires MUCH less 
bit-bending. It takes an aggressive curves adjustment to make a typical 
negative work if you scan it directly and manipulate digitally.

2. Grain reduction. A typical ISO 100 35mm negative is essentially grain-free 
in a 5x7 work print, but a scanned 35mm neg will produce a heavily granulated 
print of the same size.

3. Ability to do wide-scale dodging/burning to "pre-edit" the image without 
having to do it in the digital editor where quality is compromised. You are 
able to do wholesale brightness and contrast adjustments with little to no 
non-linear increase in grain.

4. Reference analog print gives you a starting point for editing.

5. Less dust/scratch spotting.

An argument could be made that the smoothness of a scanned print vs. a scanned 
negative is because of the loss of sharpness due to the additional process 
step. That's not necessarily true. Sharpness is usually about the same, but 
you'll avoid all the grain aliasing characteristics that occur with film 
scanning. One way around this is to do multi-pass scanning of the negatives, 
but then you run into time issues. It takes less time to make work prints from 
a roll of film and flat-bed scan the prints than it does to fight the film 
scanner.

Huh?

Well, I'm going to speak for me, but here is a typical workflow:

1. Contact print the Print File sheet. Mark the images to scan. A magnifying 
viewer is your friend. I may also scan the contact print to do some playing 
with a specific image or two to see what might be possible

2. Make 5x7 prints (image size 4x6") with basic exposure and contrast 
adjustment to get the image into the neighborhood. Nothing too fancy, just know 
that it's easier and faster here than later.

3. Scan the print.

4. Edit the image with additional spotting, sharpening, cropping, 
contrast/brightness adjustments, etc.

5. Final output.

Where I'm experimenting is with the final output going back into the analog 
form by printing out a negative on Overhead Transparancy Film, and making a 
contact print back in the darkroom again.
