On the right side of this shot, the brightness of the base of the tank seems to continue through the guy and across the back of the cab. What's going on? If it's a scanning issue, we can skip discussing it and I'll post the question when dpug gets straightened out. Velvia 100 in 120 in a Mamiya C33 with 80mm blue dot lens.

I hazard a guess that its coincidence it lines up with the truck (and theres more than one line). I rekon its either a dodgy sensor in your scanner or more likely some dust on the scanner. Depends on type of scanner. Does the neg/tranny move through the scanner or is it the scan head which moves. If its the former then probably dust on scanner glass. If its the latter then may be dust on the scanner sensor. Otherwise a dodgy scan sensor but that usually gives a black line.

Rob, thanks! I forgot to say it's an Epson flatbed.

NO IT'S NOT! This is a lab scan.

it could also be a scratch on the tranny. Check it carefully on both sides.

That really looks like a line/lines from scanning. Zoom in and you'll see it's not an extension of the image. As RobC said, its location is a coincidence. Use a loupe, or scan it yourself, for confirmation.

I had something similar, but more obvious, from a drug-store mini-lab - three rolls processed the same day. I'd thought it was a roller mark from processing as it was so prominent, but rescanning myself revealed it was not there. Something was up with the lab's scanner. This effectively ameliorated any advantage of my procrastination, and I finally did my own processing not long after.

I suggest you look directly at the slide itself (simply with your eyes) and the answer to your question should be evident. If the problem is not visible in the physical slide, it's a scanning issue.

It's Obama's fault.

That sounds like a "Trumped-Up" charge to me

Things like that is one of the things that gets me down about scanning. My KM5400 will induce scan lines on slides sometimes which bizarrely reduced when I moved all the cabling around to isolate the cable from the scanner from the others or put crossing cables at right angles. Hard to believe you would get that with a digital device but a tip and discussion I read from another forum a couple of years back pointed me to check out that solution. Also seems to be much more likely to happen IMHE when multi-pass scanning is enabled. Just writing this depressing stuff is a reminder to get to work on my own printing darkroom.

if the scanner moves the neg/tranny over the scan head then its usually dust on the internal glass which is over the scan head. Dust moves about so scan artifacts will move. But they are nearly straight lines in the resulting scan.

Lots of great information! Thanks to you all for your help.
