After importing the scans into light room and click on convert scans I get this error. “An internal error has occured - bad argument #1 to ‘pairs’ (table expected, got nil)”. The only thing that I can think of that started this error is when I started adding “film type” and “film format” in the metedata field on import(which I believe where added with negative lab pro). That the only change I have noticed that has been contributed to this error. After the initial pop up with failure message I can just launch negative lab pro again and it starts where it left off.
New to NLP as of today and I was getting this error with monochrome scans from Silverfast SE Plus 9. The were scanned as bwHRD but not 48bit RGB. I then tried scanning with vuescan set exactly the same as colour settings minus the IR scan. These opened fine as a batch of 6 files.
Maybe the others seeing this error message aren’t ensuring the files are saved as 48 bit RGB DNG’s.
I was originally replying for the same reason then remembered I read in the guide for setting up vuescan you commented that B&W should also be set as 48bit RGB .
Setting this (and turning off IR scanning for B&W) worked fine for me.
