"Update Vuescan/Silverfast DNGs" issue

Hi,

when I click onthe “Update Vuescan/Silverfast DNGs” command, and press OK then, then the below error message appears:

And at the end of the process I can’t find the NLP profile anywhere.

Any thoughts? Thanks!

Hi, are you using NLP v2.1.2? Can you tell me what operating system and lightroom version you are on?

Hi, I’m using the latest version of NLP (v2.1.2) and Lightroom Classic CC.

Can you go in Lightroom to “Help > System Info” and copy and paste that info so I can get complete picture (operating system, exact LR version number, etc).

Also, can you tell me what specific scanner model you have and what software you used for scanning (Vuescan or Silverfast).

That will provide more clues.

My initial hunch is that it is a folder permission issue with Windows (which is quite common with Windows, unfortunately). If there is a folder permission issue, it won’t be able to write the changes to the file as it should, and it is tricky to solve.

Hi Nate,

please see below my system info (sorry but it’s the italian version…hopefully you could understand the essential info):

I’m using the Epson v600 scanner and Vuescan (latest version).

Thank you.

Thanks @Rockall_8!

First, I would try updating your version of Lightroom to the latest version (LR Classic 9.1). Looks like you are still on 8.1. Some of the earlier 8.x version of Lightroom Classic had issues with folder permission and writing to file.

Upgrading alone may fix it.

If that doesn’t fix it, I would try putting part of that command in the command prompt and see if
you get any errors. Open up the command prompt, and copy/paste this and hit enter:

C: & cd "Users\rocci\Documents\NegativeLabPro.lrplugin" & win\exiftool.exe

You shouldn’t get any errors, it should just show instructions for using exiftool. If you do get errors, take a screenshot and share.

If the above works ok, then copy/paste this command and enter into command line:

C: & cd "Users\rocci\Documents\NegativeLabPro.lrplugin" & win\exiftool.exe -m -overwrite_original -E -UniqueCameraModel="Vuescan RAW" -xmp:CameraProfile="Negative Lab v2.1" "C:\Users\rocci\Pictures\2020\2020-01-11\raw0036.dng"

Again, you should get no error… just some kind of confirmation that the file was changed after a minute or so. If you get an error, screenshot and share.

Hi Nate,

sorry for the late reply, but I was only able to update LC to 9.2 now.

Unfortunetaly, your above suggestions do not seem to work. I am wondering now what wold be the gain of having that Vuescan option working…what is exactly affect of my scan file?

Thank you.

P.S.: I still don’t know why my Lightroom profile doesn’t show NLP!

Unfortunately, I also get the below when I save the converted files as TIFF positive copy within Lightroom

Hi - You technically don’t need to run that utility on the RAW DNG because the v600 profile is supported natively in NLP. What happens on your Vuescan RAW DNG if you don’t use the “Update Vuescan/Silverfast DNG” utility? So, if you just open Negative Lab Pro on the original DNG? When you open Negative Lab Pro, you should see the “profile” in Lightroom change to “Negative Lab v2.1” if everything is installed properly (and the negative itself will look darker than it did before).

If that doesn’t work, it is likely that you have either 1) Not installed the camera profiles in the proper directly or 2) did not follow the instructions correctly for making the DNG (for instance, if it is not 48-bit RGB, it won’t work).

-Nate

Thank you very much, Nate!

I’ll let you know as soon as I get new scans. This time, I’ll make sure everything is at 48-bit RGB.

Regards!

Hi Nate,

I made sure that VueScan was set at 48-bit RGB and did a new scan. This below is what I got clicking on “Update Vuescan/Silverfast DNGs”:

The profile which appears before the NLP conversion is saying “Incorporate” (this is my translation from the italian. I don’t know if the english version uses a different way). The profile switches to “Negative Lap Pro v.2.1” after the conversion only.

Please note my camera profiles are saved here:

Kind regards,
Alfredo
