Hello:

I need one commercially manufactured (not cut down from a larger sheet) sheet of film in any undamaged condition in the following sizes to test film holders I am manufacturing to make sure they are the right size and also to measure the thickness of the film itself. I will post these sizes and thicknesses after I carefully measure them. This may seem odd, but I have found that 4x5 and 8x10 films are not 4x5 or 8x10 but slightly different than those nominal dimensions. It is natural to assume that ULF sizes would not be nominal either. I could use sheets of different types of film as well.

This is an opportunity to do something that will benefit a large part of the ULF community.

I need 7x17, 8x20, 4x10, 11x14, 16x20 and 20x24 and any other size you think you might like me to manufacture.

The film can be fogged, processed or unprocessed, in or out of focus. Darkroom mistakes are very welcome.

I am happy to pay shipping and perhaps a small expense for something you would normally throw away.

Please email me at barryjyoung@yahoo.com if you can help.

Thank you.

Sure, Barry.

I have a fair number of duds (I am embarassed to say :( ) in 8x10 and 7x17. I could probably muster up some old Tri-X, FP4, HP5, and Efke PL100 in 8x10 and FP4 and PL100 in 7x17. These would all be exposed/processed films.

Note that I live in Canada so shipping would be higher than from the US so you might want to wait for more replys to save yourself a buck or two.

PM if you're interested.

Good luck with this.

I'm going out of town for 10 days, but when I get back, I can send you some 11x14" Kodak film. If that works for you, send me a PM with your address.

My 7x17" camera is in transit, so I haven't had a chance to ruin any 7x17" film yet.

Hi Daniel:

I don't need any 8x10, I have some of that (hiding my eyes in absolute shame) but one sheet of each flavor in 7x17 would be a great help. Just send me a bill and an address and I will send you dsome dough. Please mark them, I would never know which was which. Thank you

Hi Barry:

Hey, you have a very cool name.
Yes, 5x12 and 10x12 would both be excellent. Please advise where and how much.

Thanks

Barry, wouldn't there be a standard somewhere, surely the film manufacturers size to something common

There are noi ANSI standards for sizes beyond 8X10, with three exceptions: 10X12, 11X14 and 14X17. For all other formats film makers must assume that the stated size of the format is the actual size of the opening in the film holder. That is, an 8X20 format should have an actual opening of a full eight inches X twenty inches. I have seen a few older holders that have openings slightly larger than nominal, but that is not the convention today.

Film is cut just shy of the size of the format. For example, 12X20 film is actually 11 15/16 X 19 15/16, 7X7 is 6 15/16 X 7 15/16. If it is cut by mistake to the actual size of the format chances are you won't be able to load it.

Most sheet film has a thickness of 0.007". So a good appoximation of sheet film for any format could be made by cutting sheets of 0.007" polyesteer to 1/16 less than the nominal size of the format.

Hi Ray:

Different films are different thicknesses

Thank you Sandy, I guess I should have just asked you.

Hi Sandy:

What is the thickest film you have encountered?

Thank you.

Barry,

Just at 0.008".

Could be that there is some thicker but I have not encountered it.

Hello People:

Today I received the first film in the mail. An anonymous sender with no return address sent me some film from UK. Thank you so much.

I took the film to work last night and measured it carefully. Here are the results.

10X12 Maco UP100 Plus
measured 9.950x11.950 inches by .0081 thick
This is .050 under in width and .050 under in length
5x12 J&C Classic 400
measured 4.935x11.920 inches by .0077 thick
This is .065 under in width and .080 under in length
5x12 Ilford HP5 Plus
measured 4.875 X 11.955 inches by .0077 thick
This is a .125 (1/8th inch) under in width and .045 under in length

So, to answer one respondents question about a standard,,,,there is apparently no meaningful quality control on the width of film. This is exactly why I wanted samples. I have noticed big differences in film width and length in my 4x5 film, so I assumed there would be something similar in ULF films.

Thanks to everyone participating in this study and especially to the sender in the UK.

Hi Daniel:

I received the films today, thanks very much. I will get a money order out to you tomorrow morning. I really appreciate it.
