Thanks to both of you.
1 - Wolfgang, I will go through everything from that search today, and make notes.
2 - zkarj, please post a copy here when you can.
3 - From “Rangefinderforum” - turn everything off.

I thought I did a good search two/three years ago, and again about a year ago. But I was searching for updated software for my Epson. Nothing I found mentioned VueScan, or if it did, I didn’t realize I had found my answer. I had discussions with Epson (useless - buy a new scanner) and Apple - not much help from them. So, I did what seemed like a natural answer, I never updated my 2013 iMac and it has been working fine with the Epson for all these years.
Current plan is to make a list of all the VueScan items that can be “set”, and come up with four sets of configurations:
scanning printed photographs,
scanning 35mm b&w negatives,
scanning 35mm color negatives, and
scanning color slides.
I’ll post my empty list here once I have it done. It might be useful for others for keeping notes of their own settings.
So perhaps I only want to select the scanning resolution and basic functions, and turn everything else off to be done in PL4. A lot of things described in the YouTube video I linked to can be left turned off, and as suggested, that work should be done in PL4.
