The process for using Negative Lab Pro with Vuescan RAW DNG scans is very similar to the regular process of working with DSLR scans, but with a few important differences. Read on to learn more.
Preparing your image for conversion
Before beginning, be sure to you have followed the guide to creating RAW DNG files in Vuescan. If you have not followed this guide, your DNG files may not be correctly set to be converted by Negative Lab Pro.
To prepare your file in Lightroom before conversion:
Step 1. Exclude the film border - Like DSLR scans, it is generally preferable to NOT include the film border in the conversion analysis that Negative Lab Pro does. To make sure it does not throw off the conversion, you can either make sure to crop it out prior to conversion OR use the new “Border Buffer” setting to exclude a portion of the film border from the analysis.
Step 2. Don’t Use Lightroom’s White Balance Prior to Conversion - Unlike DLSR scans, you will usually get better color results by NOT white balancing off the film border prior to conversion.
Step 3. Open Negative Lab Pro, and set your “input” to "Vuescan RAW DNG
Adjust the other pre-conversion settings, and then hit convert.
After analyzing the image, it should produce an intial conversion.
NOTE: If all it set up properly, your “camera profile” will be set to “Negative Lab” at this point (or potentially during import).
If instead, the profile remains showing “embedded”, make sure your scanner is on the supported scanner list, that you have followed the instructions on creating RAW DNG files with Vuescan, and that the profiles are correctly set up in Lightroom.
Step 4 - Edit to Taste
At this point, it’s up to you to adjust the tones and colors further to your taste. This can be done using the controls in Negative Lab Pro, which are specially made for working on the original negative.
Alternatively, you can use the “Make Tiff / Jpeg Copy” feature to create a positive copy, on which you can use Lightroom’s regular controls.
