plastic sheets

Attention Sun Demon

Hi Gae and others, who are interested in the message below!

Thank you very much for your recent message. About the plastic sheets: 
I buy them in sheets of 1 m2.  You can get it in various thicknesses, I
always use about 1.5 mm. I dont know the actual name/brand. You can get
it from any retailer in photography/arts etc. also in the States. Its
rather expensive stuff!  I understood the same stuff is available in
cardboard which is much cheaper.

One side is matt white plastic (is the backside once the photo has been
glued  on) and the other side has some sort of sticky material evenly
spread over the surface ( I call it glue) and covered by white shining
plastified paper. You can tear this paper off.  Its the same idea of
sticker material!  The big advantage of this plastic sheet is, that is
very easy to cut. You just lay it on a flat surface with the glue side
down. You take a sharp knive (I use an old rasor blade) and just scratch
the size you want to have. You dont have to cut it through, just really
scratch it. Then you bend it and it will break! Easy! 

The tricky thing is to get the photo properly on and completely flat. I
lift  a small portion of the covering paper and  stick the photo on the
appearing bare glue, gradually wiping it with a piece of cloth . Then I 
slowly remove the rest of the paper while sticking the photo on the glue
and so on. Finally the whole photo is on. Its easy, but once it goes
wrong you cant tear the photo off any more and the photo is lost! I
always make the sheet a bit bigger then the photo, so there are edges
(with glue on!) left. This facilitates framing the whole lot in a
passe-partout (off course a black one with a white core, that is the
most beautiful for an infrared photo!)

I have no opinion about the plastic sheets and glue being archieval
(is this the right word?). I only know the stuff  I use is specially
made for sticking photos. So it should be allright. The Bison glue you
use could be suspicious as this is some sort of general glue for general
use. So be careful!  

Besides my 35 mm equipment I have a Bronica ETRSi  4.5x6 cm  together
with three lenses. In my opinion an ideal IR camera just as your Mamiya
645. Yours is a great camera! Im also thinking about trying Konica
750.  Sooner or later I will be glad to hear from you about your
experiences! I like the Kodak HIE because of its greater latitude. One
says that the Konica is very contrasty although sharper and has a finer
grain. Its not a real IR film, it only peaks at 750 Nm.  Could the
Ilford SFX 200 be an alternative?? In the book of Laurie White there is
an example and a comparison of the two films (Kodak and Konica). I like
the Kodak picture. Still I want to try it to convince myself! Anyway,
Ill keep you informed.

Cheers!
