Hi
A friend of mine makes gum, cyanotype and van dyke brown prints with paper
negatives by peeling the paper backing off the resin coating. The image
attaches to the resin and it very thin. You then need to use a frame to
hold it flat during exposure but the exposure times are very reasonabl
Not if you follow the directions in the book. Without those steps, it tends to
be an unsatisfactory mess.

These are great negs, especially with the pictorico film. Dan Burkholders
book "Making Digital negatives for contact printing" will tell you how to do
it.

Hi
Cheers for your reply, do the negatives you make on ohp acetate, lose alot of
the contrast, does it hamper the quality of the image?
Hi Ben, another 'work-around' would be to make digital negatives on OHP from
these folks: http://www.pictorico.com. For me, the sun exposure for these
on cyanotype is about 3 - 4 minutes.

Actually, everything behind the pinhole gets the same amount of focus.
Therefore, if there is dust on the filter, the dust will be in focus
regatdless of which side of the pinhile the filter is on. However, once
the filter is clean, it is much easier to keep it clean if it is inside
the camera
