Using Negative Lab Pro with Vuescan RAW DNG scans

UPDATE 12/2/2019 - With the updates to v2.1, the directions have changed slightly to reflect the new dual-illuminant profiles and dng compatibility utility. As such, I’ve also removed some of the questions and responses in the comments, as they would have been misleading given the new directions.

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. After import, set your “profile” in Lightroom to "Negative Lab v2.1"
If you do not see this as an option, this means that you need to run the “Update Vuescan DNG” utility which will make the selected images compatible with the correct profiles. To run this option, select all the Vuescan DNG images from your import, and go to “File > Plugin-Extras > Update Vuescan/Silverfast RAW DNGs” then follow instructions. If it works, you should see the profiles change to “Negative Lab Pro v2.1”

Step 2. Exclude the film border or use “Border Buffer” - 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 3. Use Lightroom’s White Balance tool Prior to Conversion - As of Negative Lab Pro v2.1, it is recommended to use the wb tool in Lightroom prior to conversion. Try and use the wb picker tool to select a blank area of the film border. If you don’t have any film border to select from, you can also use Lightroom’s “Auto” wb setting (in some cases, this may produce better results).

Step 4. Open Negative Lab Pro, and set your “input” to "Vuescan/SF RAW DNG

Adjust the other pre-conversion settings, and then hit convert.

After analyzing the image, it should produce an intial conversion.

Step 5 - 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.

Does anyone know how to add the camera raw profile suggested above. I’m on a mac and can’t find the folder. >.<

How/where should I create the folder if it doesn’t download automatically to lightroom. Photoshop tries to open it with an error message, and I can’t locate the folder listed here.

Hi there, I’ve heard a lot of good about NLP and I am trying it out, but my conversion ends on an (incomplete) error window saying there is probably a problem with folder permissions … I tried unlocking the NLP folder from read only, but it doesn’t allow me … Any opinions ?

Error : Could not write photo for analysis

Hi,

I’m assuming this is Windows? Windows folder permissions are a pain. The easiest thing to do is to relocate the plugin folder to a place where YOU have complete ownership… I would recommend trying the root of the C:\ drive and seeing if that works. You’ll need to remove from “file > plugin manager” and then re-add from new location.

Hi Nate, so I noticed, I tried by all means to have permission, but no use…
I just found the way out, indeed by moving the plugin folder (uninstalled NLP, moved to another drive, reinstalled the plugin) - A genuine pain in the … this problem was … Thank goodness it’s solved
