Yes, it's the scanner. I need to get that pile of junk cleaned one day soon. I would replace it if there was any reasonably priced alternative that takes 8x10" negatives!
I haven't printed all of these negatives yet, so I'm using the scans I made to decide which ones to print (and how) for posting since that's what was on my computer. I'll replace them with properly scanned proper prints as soon as possible!
