View Full Version : Utility of excess cut down film?
Hi there,
Cutting down 8x10" infrared film, to whole plate format (6 1/2 x 8 1/2 inch), I'm left with strips of approximately 1 1/2 inches.
I wonder if other users have found any creative or useful purpose for these remainders?
RJ
possibly to be used as test strips for creative exposure?
Hi Ash,
Thanks for the thoughts - I've nailed the exposure for the film ... it's only taken 6 years!
I was wondering if any one has any experience of using IR film like this for internegative contacts which could then be enlarged as 5" x 1 1/2 " panorama formats.
Kind regards,
RJ

Make a box with pinholes on 4 sides.
Make a 360 degree picture with your leftovers.
see illustr.
Thank you Jim - that's very creative.
Do you have a working example?

Not yet. Looked like it might be kind of fun though. I've fallen behind on just about everything but ideas. :D jg
you can also use these scraps to test your fixer.
when you mix a batch of new fixer, see how long it takes to
clear the film ( exposed to room light ) note the time ..
use your fixer until it taxes 2 times the time to clear your film ...

Here's a question:
There is aerial survey film appearing on the auction site. Is it a real bitch to cut down film from a 5" wide roll into 4x5 sheets?
I don't have a darkroom to try it myself and the house freezer is chock full of food, so you couldn't get a roll of Panatomic X in there if you wanted to.
It was one of those films I only used once (in 1987). There wasn't anything bad about it, I was just spoilt for choice at the time and my preference was East German ORWO NP15.
If you want a slow film there's the EFKE. What does the Kodak do that is enough to make you go to such lengths of cutting down a massive roll?

google 'tortuga pinhole camera' to see working multi-pinhole panpramic camera.

forgive imbecile spelling
Thanks for your thoughts everyone.
Neil - cutting down 5" x 4" from 5" aerial roll is very straightforward, particularly with only one cut per sheet. The aerial emulsion has a thinner base than sheet film, however if you're accustomed to Panatomic X; aerial sheet film and Rollei IR sheet film, then it's straightforward adding a notch to the emulsion side.
The Orwo NP15 still exists in various marketing reformulations as a single layer emulsion, including a beautiful revision by Bergger (NP15) and Wephota. The rationale for cutting down film to whole plate format is, that there is no current infrared film on the market; Rollei, Efke and Maco won't be releasing infrared film in this format anytime soon.
Kind regards,
RJ

Neil, I confess to being an aerial recon film cutter upper. I've found the 4X5 is more trouble than it's worth. The base of this stuff is like 3 mils. The natural curl of the film holds it to the back of the film holder so flatness is easy enough. I don't notch as it curls into the emulsion so no need. The trouble I have with the 5X4 is in the development. Its so thin and bendy it won't stay put in any of the Jobo tanks or anything else I can think of. Now 5X7 solves all of those problems and I do it quite a bit. The Panatomic Aerial film has a grain structure just like Technical Pan. You can't find it with a 10X loupe. It is extremely contrasty so that is a consideration. In flat lighting and under the right conditions it is one of the most beautiful films for Pt Pd printing I've ever encountered. It just glows.

test it out in an SLR. Roll up or cut into pieces and place on the gate singularly.
SOS - thanks for the suggestion. Unfortunately IR sheet film is already very grainy before cutting further down to 35mm sections.
Theoretically, I guess it is possible to use the strip to create an interpositive, exposed through an infrared filter on the enlarger, in order to create an infrared image from a non-infrared positive?
Jim - the only method for developing 5x4" Panatomic X which I am aware of relies on the deep tank method, availing of the four cornered crocodile clips. I can imagine its application for alternative processes as you have mentioned; it is very striking in semi-standing concentrations of an acutance developer too.
Kind regards,
RJ
