8x20" color film

[Prack]

Hello from austria and here my first question.
Would like to move up to 8x20" and my interest is doing color photography, but color film for larger than 8x10" seems to be impossible to get.

Does anyone use color here, larger than 8x10"?
So what can I do to get 8x20" material.

regards Prack

Want color negative, because for portrait.
And develop C41 myself.

 

[nickandre]

you could buy 16x20 paper and cut it in half. try this link for some 12x20. If you cut 3 inches off the top it might work.

and you're in luck, that's the only film I can find.

47 boxes NC160...

...sounds good, will think about it and must work more.
For a min. Qty. 47 boxes - over $ 15 000,-
But if this is a special order, perhaps Kodak can do 8x20 too.
Will ask them.
Thanks

Agfa as well as Kodak offer 9.7/16” resp. 9.5" wide rolls of C-41 colour aero films.

So you could try those after cutting to the size you need. Either contact their local agents for complete rolls or contact a local aero surveyor and inform about roll ends.

Keep in mind that the base for the aerographic films is thinner than that of cut sheet films and my not stay flat well.

Mapping cameras have a vacuum platen to hold the film flat.

Aerial films are manufactured with TAC as well as with PET bases and in base thicknesses of 60μm and 100μm.

The 5 films I referred to are all on 100μm PET base, which should add to stability.

For comparison: Kodak Tri-X 320 and Ilford Delta 100 sheet films have a 180μm PET base.


But I guess film stabililty in ULF is an issue anyway.

Vacuum Plate:
That venture Gigapxl uses a modified Fairchild 9x18" camera with vacuum plate. Not very practical though.

A light weight alternative would be using sheet film, a modified holder and a flat, sturdy plate coated with an adhasion layer and changing film sheets in a changing tent.
