I do something slightly different that I find helps with my workflow.
I set Media to “Color Negative” then check the box for “Raw save film”. In addition, I tick the box for JPEG file.
What this does is that it will output the RAW DNG containing the negative (for use in NLP), but also creates a positive JPEG version of each scanned images (converted by Vuescan).
The reason I find this useful is that Finder cannot display DNG files, so having a JPEG sitting along side each RAW DNG file makes it possible to examine the contents of each scanned negative in the Finder. I find that Vuescan will sometimes forget what crop settings have been made for each image halfway through a batch scan or decide suddenly to use the List batch from the previous can session. Having JPEGs right there in a finder lets me quickly check that all the images were scanned correctly.
Because the JPEGs are only used as a quick reference, I don’t spend any time making adjustments in the Color tab.
