My comment isn't about vuescan and Silverfast
But for my use, scanning many dias images form 1960-1980 I scan at 1200 dpi. I actually think Epson Scan software works better than vuescan. And easy, a simple as set the options you like save as a scan profile hit prescan check everything looks as expected. Hit the scan button wait 2 minutes, open cover, replace the 4 images close lid, hit scan without doing anything else and repeat. For my setup vuescan did a bad job with cropping. I'm using i Epson v600
when you choose Raw in Vuescan (tiff or DNG) it will save uninverted image, it's basically the raw data scanner reads from your medium. If you choose Tiff, not raw, you will get positive image. You could be confusing DNG tiff output with raw DNG output. DNG is simply a file format wrapper. I always use Raw output, not DNG anything, this gives me a tiff file, uninverted, no adjustments by scanner and gamma 1.0 value. You can wrap it in DNG after the fact too. Lightroom e.g will let you do so on import.
If you want to keep some filter and other adjustments in raw files, you need to choose 'Output with...Save' not 'Scan'. It's all on the vuescan website.

I gave up on vuescan for color neg film. In my experience it was totally useless. And with Ektar film specifically, it just gets maddening because of high contrast of the film. Even after locking exposure, base color, etc the vuescan still tries to guess exposure and balance for each frame and usually it royally screws it up. I could only find two ways to make it work with color neg film:
Anyway, for B/W work I love vuescan, but for color, I switched back to EPSONscan. It's not perfect, but results are at least useful. And if I see a frame that deserves extra work, I can rescan it raw and invert/color-balance manually.
First on the router, you must assign a fixed IP to your multifunction printer. Once this is done, you need to open the firewall ports on your PC.Open the terminal and enter the following rule:"sudo ufw allow from xxx.xxx.xxx.xxx" without the quotes.Where in place of the X you have to put the real IP of your multifunction printer.Now vuescan will work.Then to delete the rule always from terminal type:"sudo ufw delete allow xxx.xxx.xxx.xxx"
While the concept and intentions of this app are great, it's extremely difficult to locate essential features such as a cmd for scanning multi-page or duplex documents as one .pdf file. Even more frustrating, to simply ask how to accomplish single-pdf file scans, Ed Hamrick demands a copy of the "vuescan.log" file which contains unrelated, non-pertinent OS and system details for a question unrelated to application features (or even scanner issues for that matter). I just don't feel comfortable releasing that information, nor was it necessary for our question (again, only a features question). There was no "problem."
Great thread as I also have an 8300 and use vuescan and am always looking to improve my scans. I wish I could find it, but Ghost Town had also offered some advice to me so I will be testing your settings in comparison (eventually). As far as the glare on the cases I think it depends on the colors of the cover of the book being scanned along with the type of slab itself.
yay -S vuescan-bin, the PKGBUILD then automatically grabs the latest version.Sometimes you also have to use the Packages to cleanBuild? option since the software author does not always rename the version on their website when making very small updates.
These timeouts happen when the script is trying to download some of the OCR packages. My internet connection is stable (1 Gbit/s down via optical fiber) and I only ever have such issues with vuescan-bin.
Today i installed my epson xp-201 printer/scanner to scan some photos. I was able to scan once, but when i want to scan another photo, it never worked again.
When i ran scanimage -L, i saw the scanner just once too, and it never appeared again. I changed the usb cable, and rebooted the system several times with same results.
But, vuescan works perfect. It's so weird...
I have been trying to find a solution for a scanner problem I have for a Canon LIDE 210 which won't work when plugged into a usb3 port but works fine when plugged into a usb2 port on an older machine - using xsane from GIMP. I am going to try to test with vuescan but I wonder if your scanner was connected via a usb3 port? If so it might indicate a corresponding issue to the one that I had. I have seen a Ubuntu posting that vuescan worked where other scanning software didn't so I was interested to see if there is a common underlying cause here?
I tested vuescan today with my Canoscan LIDE 210 - and it works fine when connected to a laptop with USB3 connection, where the scanner jams solid with xsane. This is interesting and seems to indicate a bug in xsane when using USB3. Maybe it is worth putting in a bug report upstream to the sane-devel list.
