European glass not available in the US

[Katastrofo]

No, the negs are taped to the cut glass and it has thin black cardboard
squares in each corner. The film is taped to the glass shiny side of neg touching glass, then I horizontal flip in PS. Needs tweaking, but am
somewhat encouraged.

[Katastrofo]

After doing some comparisons with the stock filmholders, it's back to the
drawing board. Betterscanning beckons...

Here's a comparison of stock filmholder and using the frame glass:

filmholder


frame glass


Both scans, same settings, just resized and some sharpening is all.

The frame glass must have a coating, not ground like I hoped. Gives a very aberrant histogram with a quarter inch gap! Trying to cure it's hazy glare and lack of contrast was a waste of time. Oh well. I think any coating, or using magic tape, would yield the same crappy or crappier
results. Just an FYI.

Was the glass thickness correct? The holders are designed to hold the negative a certain distance from the scanner lens. Very noticeable difference between the samples.

I don't think I really understand what you're attempting here Bill. Why do you need to have a coated or ground glass between the scanner lens and the film? If you need to use glass for mounting, wouldn't it be best to use plain clear glass with the film below it? (i.e. with the film sandwiched between the platen and your glass). That way the glass wouldn't affect the scanner definition. All you'd need to do is make sure the film is spaced away from the glass to avoid Newtons rings and to get proper focus.

Alessandro, I mentioned Betterscanning in my above post and am familiar
with Doug's offerings.

Mike, thickness of glass is not that important, distance from scanning bed
is, and determined by the cardboard pads in each corner of the cut glass.
I'm using this much like the ANR glass where you have the curved side of
the negative facing the cut glass where it is taped flat to it and facing
towards the scanning bed. Something is giving me killer glare, either from
the coating on the cut glass which I'd hoped was ground but isn't or the
masking I'm using (construction paper). The construction paper I positioned
on other side of cut glass and it wasn't taped down, just resting on the cut
glass. I'll try a few more things, but I think the culprit is in the coating on
the glass.

Peter, in my above setup, am I doing something drastically wrong?

Bill

[maddog10]

Is light leaking in from the sides? The holders somewhat keep this from happening. Did you try it with the white background, instead of the black?

[Katastrofo]

The one thing or actually two things I'll try is no masking whatsoever, or
tape the masking down on the same side as the negative. Here's a scan
where the negative is resting right on the scanner bed held down by coins,
nothing else:



This is using the the Epson 2450. If it was 1mm above the scanning bed,
sharpness would've been improved. But there are no glare or contrast
problems.

Bil

[Xpres]

Bill - You mention ANR glass. Couldn't you use that? I use a 5x4 piece in the neg carrier of my enlarger - it came with it, but surely can't be that hard to get hold of. ebay maybe?

Xpres, I can get ANR glass from Betterscanning, but they are cut for
specific filmholders, nothing larger.

[peterqd]

[Katastrofo]

Peter, yes the film is taped to the underside of the glass, so nothing between
Scanner bed and film. Taping the film to the etched or dull side was to
alleviate Newton rings, but moot point if film is taped flat to glass, correct?
I'm not the author of this method, merely trying to adapt to its description
with materials at hand.

I just checked and single strength windowpane would run only $2.30, same
dimensions.

Bill

[peterqd]

OK, now I'm clear. Looking at the scans you posted, the film and the scanner are OK, so the contrast problem has to be caused by the extra glass.

If the only reason for using the glass is to keep the film flat, could I suggest you get rid of it and make a mask from your black card, with a 56 x 56mm cut out, and tape the film to the underside. I'm not sure you need to worry about focus too much because the scanner is designed to focus on documents directly on the flatbed - maybe the depth of field of the lens covers a few mm variation. Using the coins under the film to space away from the flatbed glass is a great idea.

Peter, think I'll just get ANR inserts for my filmholders from Betterscanning
and be done with this. For one, this is way too fiddly if you have a lot of
scans to do.
