Hi:
you can make cyanotypes from a paper negative. It just takes a long time.
A friend of mine has done this - he needed to expose these for three hours
in the sun.
You could try waxing the paper negatives to make them more transparent.
People have had success using melted parafin wax.

The Polaroid website has reciprocity charts films they sell. Go to
polaroid.com, click site map in the upper right corner and then to customer
support.

Does anybody have a good chart that tells me what I should be shooting at
film based on Polaroid test exposures?
Please email direct if you have one available,

Dusties have no problem getting projected onto the film when the filter
is behind the pinhole- I know this from painful personal experience!
Moral-
It really should not matter which side of the pinhole you place the filter.
I guess you would have to weigh ease of removal to the possibility of lens
flair and decide which fits the way you work.

Hi all,
I'm the proud new owner of a Kurt Mottweiler studio Pinormaic 120
camera. I have been wanting for many years, and when I saw one on ebay I
had to snap it up. Any way you can see a couple of examples at:
