vuescan and "long" negatives

[dan dumitru]

To all,
I am new to the group and was wondering if anyone can advise on the
following.

I have a nikon 8000ed scanner using vuescan and was wondering if it is
possible to have vuescan scan a negative that has a size of 6x17 cm.
The negative carrier is certainly long enough to handle this size
negative and the carrier goes all the way into the scanner when
scanning several negatives in a row. It seems that it should be
possible to have the software of vuescan tell the scanner to continue
scanning for a size of 6x17 cm. I have written to Mr. Hamrick the
developer of Vuescan but not heard back from him yet. This would
permit photographers shooting large panorama negatives (6x12cm and
6x17cm) to not have to use a drum scanner or a 5x7 enlarger and go
digital economically.

thank you for any advice or suggestions,
Dan

The problem is the same as with the Coolscan 35 mm scanners: there are
two mechanically separate drive mechanisms. One has rather coarse steps
to advance the film strip or neg carrier to the next frame. The other
one operates at the much finer scanning step width and moves the CCD
carriage during the actual scanning process. Get the point?

Use a flatbed like a Epson 4870 to scan the whole thing or scan it in chunks
on your nikon and use the stitch function in photoshop or another
application like Panorama Factory.

You can scan in two sections and merge in photoshop. Quite simple.

The real problem is holding a 6x17 cm frame flat enough. The glass carrier
may or may not cause Newton's rings. If you luck out and it doesn't, then
you're home free. But if you get Newton's rings, the alternatives usually
sag in the middle enough that you can't maintain sharp focus across the
whole frame.
