expo2: 6x6 transparencies

[P3D Elliott Swanson <elliott@xxxxxxxxxxxxxxxxxxxx>]

There are some technically stunning 6x6 slides in giant paired mounts
(does anyone know a source for side by side 6x6 and 6x4.5 mounts?) taken
by Don Lopp, Joel Alpers, and Greg Erker. The most interesting is Joel's
slide Calypso Cascades, shot with a Sputnik and on Ilford FP4 and contact
printed on Kodak Technical Pan film. This was apparently Joel's first
attempt at a B/W positive in this format, and it worked very well.  The
image has a luminous quality. The 63mm stereo base of the Sputnik gives 
it some real potential for working fairly close.

Joel noted the small amount of flare in one image, which is not
objectionable, but makes one think about fabricating shades for the
camera. Also, Don Lopp was explaining to me his system of blocking
internal reflections and light leaks some Sputniks seem to have (he cuts a
paper mask, painted flat black, and mounts one in the left and right
compartment of the camera, about a half inch in from the film plane (e.g. 
between the film plane and the lens. One would need to experiment and
check the light path with the back open, the lens locked open, and a
ground glass in place for determining the side widths of the mask
apertures.)

(Joel, could you supply more info on the Ilford FP4/Tech Pan process? Looks 
like an enlarger is not necessary. Which is good, because I don't have one.)

There's also a pretty wild home-built 6x6 viewer with expo2, but these
images are so large, and my vision requires something like -5 diopters of 
correction, that I found it easier to just free view them.
