Is this "discernable" pattern you are seeing in the print repeated in

the same area when you make duplicate prints? At what point in the

processeing do you see the "pattern"? I wonder if it is a build up of

mid tone density through the infectious development? Additionally,

what paper are you using? Is the pattern in the same place every

time?

the 405 back is for pack film in the 4x5 size, as opposed to the 545i

which accepts individual sheets of film. Either size should work on

your Pinhole camera, as both the 405 and 545 are of the same mounting

dimension.

The paper that you use will make a difference on the results. Try Arches hot pressed 140lb and let the transfer stay on the paper for 2 minutes. Keep the transfer warm during the transfer process with hair dryer......lightly over the back of the print (negative). Not too hot, and not too forceful. Then, place the entire transfer and neg. sandwich into a tray of warm water, and peel very slowly.

There are some good books on the precess, Kathleen Thurmond-Karr(spelling?) has a new book out, as well as some publications from polaroid. Check out their web site polaroid.com.

Experimentation ans persistance will pay off well.

I have a Carl Zeiss, JENA 21 cm lens for my speed graphic. (serial #Nr237016) Tessar 1:4.5 DRP. The len's f-stops are marked as follows: 4.5, 6.3, 9, 12, 18, 25, 36,50. Can anyone help me with the conventional f-stop equivalents? I don't think they are US Stops.

Thank you in advance.
