Title: SilverFast Contact Sheet on v750
Post by: drralph on February 16, 2017, 04:46:08 pm
I would like to make a quick and dirty catalogue of my negative archive by scanning full PrintFile sheets.  The sheets fit on the scanning bed of my Epson v750.  I laid the Film Area Guide on the glass before laying down the sheet of negatives.  However, the resulting scan is only the 5.5" wide hi-res central area of the bed.  How do I get a scan of the full bed?

Use the Manual workflow pilot (red globe in the the upper left corner of the interface.
Go to the scan dimensions panel.
Select the expert settings (click on the gear wheel)
Place the red frame around the area you want scanned.
Check whether this gives you the linear dimensions you need, which you can read in the Expert dialog
If yes, scan,
If not, amend the dimensions in those boxes and watch that the red frame properly surrounds the area you want scanned.
Make sure you have selected the PPI resolution you want.
Scan.

You are using the "high resolution" lens that has a narrower field of view.  Additionally, it is not optimized to give the best focus when scanning items at the glass bed level.  In your software settings, you need to change to Silverfast's equivalent of EpsonScan's "film with film area guide" setting.  That will change to the other lens that is supposed to focus at the glass bed level and will allow you to scan the full width of the film area guide.

We tried this and found that even when the settings are as ideal as we could get the images weren't good enough to use. Hope you can do better.

What did you try? Whose post are you referring to?

Scanning roll of 35 in Print file sheet/sleeves. The layer of plastic (mylar?) between the film and the scanner glass diffused the image too much to use. Biggest complaint - could not tell if eyes were open or not in a crowd shot.

What do you expect if you are doing that? The film strips MUST be removed from those plastic sleeves.

Our solution - not at all practical - was taping the strips to a sheet of Lexan and carefully (!) positioning the half sandwich on the scanner glass. One or two rolls, here and there, not so bad, daily? - find some other fool, thank you.

Hey Mark - OP says he wants to scan _full_ sheets.

Reply #7 is abusive and unproductive, which removes me from further participation in this discussion, save to say that whatever the OP wants to do, correct practice is to put the bare films strips into the film strip holder (which covers the whole page) or onto the Epson FMA and scan. Signing out.

Did you actually have to scan the film to deduce the images would be useless if you scan them through the Mylar? Common sense would dictate this.

The scanning was done by direction. Not by choice.
