Strange issue with the coolscan 5000

[sanmich]

I have a strange darker band on the left side of some of the frames (the side of the neg first entering the scanner).

First, I thought it was a capping issue, but then I tried to rescan the opposite way, and... no band!

It appears only in bright skies.

It bugs me and I would like to solve the issue if possible, so if you have any idea what can be the problem, please share your experience...

Thanks!

Your post made me rethink an observation of mine. I have these lighter bands on some slides and (wrongly) assumed it would be light entering the feeder while scanning the last frame. But (as you said) it is the first frame and in my case (being slides) lighter bands.
Now I'm also bugged... and hope for an explanation / solution too.

Bumpity bump

My friend Alex has the same problem on his coolscan IV, so it looks like it's kind of a feature.
Anyone with a solution??
(other than switching to digital as Alex suggests)

Its flare caused by light coming in next to the negative. The image must be right up against the edge of the opening in the film holder to prevent it. My LS-8000 does it too. All the Nikons do.

Have a look here, Michael:

The right thing to do is find an FH-3.

Chris, Roland, Thanks gentlemen!
🙂

I do have the FH-3 and will use it for critical scanning.
99% of the time, I use the full roll ability of the 5000 which was the main reason for purchase (before the prices started their little space program)

I've never had this issue, and I don't have the FH-3 (where the h311 can you find it, anyway?? I can't for the life of me find one) holder. I do have the full roll loader, and use it 90% of the time with my Coolscan 5000.

I owned the 9000 for a few months and also never saw this issue.

Judging from some of the comments above, I'd look into the mirror that is used for the lamp inside. I've heard of some flaring and other unwanted effects due to this.

Always always cover your scanner when not in use. Store it properly. Keep the area clean where it is.

Gabriel, I use the roll loader too.

These days I rarely run into this anymore, also with roll holder. What I'm doing different:

- I am much more careful keeping my film flat when drying.
- I always have a dummy "lead frame" (I shoot the first 3 film frames without lens cap at reasonable exposure). When scanning the roll, I also scan the dummy frame.

IMO, the issue is caused by film curling; somehow, with flatter film, the scanner has an easier time aligning to the frame boundary.

Roland,

How do you do that?
A special hanging technique?

 

[ferider]

I hang them up vertically using old-fashioned wood cloth pins (that the right word?), and put a cloth pin at film end as weight, Michael.

Perhaps I've never seen it because I became OCD for keeping my film as uncurled as possible, and I learned early on to have a "lead frame" also, but my motive was to circumvent a very annoying issue with Nikon's frame-detecting algorithm --for which I've learned to do the roll scan in two batches, but without cutting, because sometimes it just goes crazy, and VueScan is no better at this, it just messes up the frame spacing if you do a batch scan.
