[BOB KISS]

DEAR JOE,
	Click this link to see the PDF Kodak info sheet on Kodak RA X-ray
duplicating film.

	www.carestreamhealth.com/raDuplicatiing_brochure_M6-238.pdf

	It is a direct positive film that can be tray developed in
Dektol/D-72, D-19, D-11 etc, depending on the contrast you want.  I think
the largest size I bought was 14X17 inches but the available sizes are on
the data sheet mentioned above.
	I have used it and found that I got a much better neg by flashing
the entire film first then doing a test strip under the enlarger for
whatever neg I wanted to enlarge.  I made some nice PT/PD prints from these
negs.  The exposures are pretty long.
	I must admit that I have done digital and now make enlarged diginegs
with my Epson 3800.  I find that I really like the work I can do on the
image in Frotoshop...just easier than dodging and burning under the
enlarger.
	The minimum order directly from the supplier is very large so I
bought mine from the local radiology (X-ray, CT scan, etc) lab.  They are
often happy to sell you a box as they often order by the case.  Further, as
they often use the copies for insurance and/or legal purposes, they must use
fresh film and are happy to sell off boxes that are nearing their
expiration...still great for our uses.
*****Don't forget...Test!  Test!  Test!
			CHEERS!

David,
Could you talk a little on medical dupe film?
I have been trying to get a good,working neg, off of APHS positive,made from

a 4x5. I'm just starting,but cant seem to  to the point where the neg wii
not be blown out on the highlights. I'm sure I will accomplish it, given a
long life.
Will medical dupe film eliminate this? Are 8x10 sheets(or something close in

size) expensive and where do you get them?
Thank you
joe azoti
