I read about this discussion - someone on a different forum sent me a link to it. I just read the entire discussion, beginning to end.
My goal is to start with negatives taken (both older and now) on a 35mm film camera, and get them into my macOS computer so I can edit them in DxO PhotoLab4. I used to use my Epson V500 PHOTO scanner, but from all the reading I did, I bought what I think is the latest Plustek OpticFilm scanner. I've been getting a LOT of feedback in the Leica "l-camera-forum.com".
What I think I learned in this discussion, is that there is no single universal answer for which scanner "is best", but the scanner is just another tool, and people who are talented enough to get the best out of their tools can create excellent scans.
I started out with 120 film in a box camera, and then advanced to my dad's Contax II camera. That changed into a Nikon SP, which changed into a Leica M2, until I discovered digital, and I've been growing up with digital ever since. I kept my old film cameras (Nikon F4, F2, Contarex, Contax IIa, Leica M3, M2, and so on - they have been sitting in a drawer somewhere in my home for half a century. I got the desire to soot film again, dusted off the M3, and started using it. It's been a fascinating experience, and I want to continue.
For a scanner, I figured out how to use the Epson scanning accessories, and over the past year or so, I managed to learn once again how to use film, and then how to scan it. My darkroom is long since sold, so I figure either I get to scan my images, or have the processing lab do it for me.
Fast forward to the present. After a week or two of searching (I didn't know about this thread until today) I selected the latest Plustek, and a few days after I paid B&H Photo $500, it arrived. It came with Silverfast software, which I ignored, and I found that my copy of VueScan worked just fine - but it took several days of reading, watching YouTube videos, and finally testing to get used to it. As far as I can tell, it works fine. The advice I was given was to only use the scanner to get the image into my computer, and to avoid losing data, to keep it a "flat", minimal contrast image, and then bring it to life in my editing software. If I'm allowed to do that (as a new user here) I'll post one image below.
My thoughts on this discussion, as a new participant, are that a lot of it was meaningless to me "my scanner is better than yours" debate. Still, there were plenty of good solid reasons for using different techniques and products, and I decided that with enough information and time, I could probably make any of them work for me, including my old Epson. What I didn't find in the 8 pages of this discussion, was a good description of how to get one of them to work at its best - hints for user settings, and what I should be trying to accomplish in my scanning. Most of that I found out in the Leica forum by asking questions, and repeating what I was told, to be sure I understood it properly.
I think I'll post this now, as-is, and try to post another response with an image attached, if the software here allows me to do so.
Thank you all - lots of good solid information buried away in this thread!
