Slide mount scanning

[pshinkaw]

I have had some problems with curling negatives. The negative holder on my Canonoscan 1230U is sometimes unable to hold a very strongly curled negative in position.

I recently tried using a plastic 35mm slide mount to hold a negative. The mount was one of the slip in type, an old Agfachrome slide mount. I replaced the transparency with the black and white negative, inserted it into the transparency holder and scanned it.

This is the result.

By the way, the photo was made on Fortepan 200 in a Zorki-3M, Jupiter-8, 1/500@f11. Developed in D-76.

I think its cool and interesting that you have hit on this idea.

I had recently noticed I was getting chrisper scans from mounted slides than from my negatives. I was begining to wonder if the slide holder was performing better than my negative holder. I use a Canon 8400f.

Definitely worth trying. It would beat out the idea for wet mounting when it comes to convenience.

Now if I can find a supply of slide mounts. Hmmmmmmm...

Many photo supply vendors offer the PAKON plastic slide mounts. You can purchase them in quantities of 100, or a bulk pack of 2500. These are used by most commercial independent slide processing labs, as they fit automatic mounting machines. However, they are easily used one at a time manually, and the 100 pack comes with a little "jig" to spread the lips of the mount apart so a slide or negative can easily be slid in. I have used them for years for mounting 35mm transparencys I process in my lab, using the little jig for mounting. This is the most economical choice in slide mounts, whether you are mounting slides or negatives.

Bear in mind that you will lose the outermost edge of your image when you put it into a slide mount.

I think the Agfachrome mount I used is a Pakon. I didn't know that they were still in production.

The trial I performed above was on the end negative in a strip, so I didn't cut the negative. I just slipped it in. Obviously an interior frame on a strip would have to be cut.

I wonder if there are any other mounts out there that would work without cutting the negative strip? For example, could the glass be removed from a glass mount?

Can anyone explain why this happens? I use an Epson flatbed scanner with a film scanning attachment. When I scan the slide in the slide mount, the outer edges are cut off. If I remove the slide from the mount and put it in the 35mm film carrier, it scans the whole image. It looks to me like the same amount of the slide is showing in both cases and the carrier is just about the same thickness as the slide mount. Is this due to the programming in the scanner software or what? I kind of hate to remove the slides from the mounts as I'm afraid of damaging the slide.

I use slide mounts for film as well - i bought my Epson 3200 without the trans holders and had to improvise. I am not totally happy with it though, there must be a better way... (I keep looking on the Bay for a 4x5 trans holder and a 35mm holder but no luck yet...)
the other thing is I curiously don't seem to get as good results doing this with my Coolscan IV - (as I do on the Epson) don't know why that is though...

Losing outermost edges of mounted slides; why... Measure the slide-mount's opening, then measure the unmounted film's image and you'll find that the mount opening is smaller enough to handle inexact placement of the cut slide. So there's a little bit of masking that's normal.
