Are there any commercial sources for film holders that allow one to use 10"x10" aerial sheet film or aerial roll film that's been cut down to 9.5"x9.5" sheets? Reconfiguring my Toyo 810G to work with holders for either of these formats would be fairly easy and straightforward, but making a film holder that is both easy to load and holds the film flat would be a considerable project given the resources available to me.

Also, does anyone have any idea -- a guess, even -- how long the aerial imaging industry is likely to rely upon film before it, too, evolves to digital? I ask because if I can't reasonably insure myself I have at least, say, five years to shoot with aerial film, I'm not sure it'll be worthwhile to invest the time and money necessary to pursue this approach.

(And Yes, I realize this might read like a troll given my previous post asking about how to shoot 8x10 color cheaply. While it's true that I'd like to keep the cost of my photography as low as possible, it's also true that I waste 20% of my film-and-processing costs because I shoot square and end up cropping 8x10 sheets of film back to 8x8 when printing. If I can shoot 10x10 or 9.5x9.5 for not too much more money, the additional expense will, IMO, be more than offset by the increase in film area and the resulting lower enlargement ratio I'll have to work with...)
