I naively pounced on a set and paid his $10 s/h only to receive them wrapped in a paper towel or similar and a bubble envelope..that kind of galls me he needs to make doctor's offcie hourly rate for his packaging time.

I would determine this with the normal development time for the film which you now use. I would then seek to gain this degree of density gradient with a lithographic film. I would presume that a lithographic film would prove the most advantageous to your desired objective since it would not contain the consideration of film granularity. I have used the Aristo half tone lithographic film available from Freestyle for masking of negatives and under proper dilution with Dektol a low contrast negative can be obtained. Additionally the thinner base of this film would stand you in better stead. Making a sandwich of this film negative and two pieces of glass or thin acrylic would allow you to use this in a Cokin type of film holder. If you desire the dilutions that I use for my masking, you may email me and I will get those to you.

Having been of the opinion that the 4X5, the 8X10, and the 11X14 all possess an aspect ratio leaning too much to the square and that the banquet size formats with the exception of the 12X20 are too rectangular. I came up with the idea of the 10X16 format. This aspect ratio is more toward the "golden mean". The film could be available from several sources as special order and even by cutting a sheet of 16X20 into two sheets.
