Kind of like asking Ford to make ten 1965 Mustang replicas every year just for special customers. Can you imagine how hard / expensive that would get?

By far my favorite analogy yet...

The problem, it would seem, is that Ford is way too big - and in too much competitive financial trouble - for this to be worth their time.

However, my 16-year-old son tells me that there are currently so many small niche companies profitably supplying aftermarket Mustang parts to the Mustang niche market that one could assemble a brand new, perfectly workable 2007 (1965) Mustang from aftermarket catalog offerings alone.

The solution, it would seem, is simply staring everyone in the face...

The thing with colour infrared film is there is no digital equivalent is there?

Agfa aerial put out a statement claiming they would provide film at least until 2009. I know people cut down B&W aerial film for use in film holders so I guess you could do it with the other films also.

On a side note, aerial film is rather thin, it is not very suitable for a standard LF film holder. Aerial film magazines use a vacuum for flatness.

Ken;

Yes, it might be if getting custom organic chemicals was as easy as getting aftermarket Mustang parts. But, you will find that the organic chemicals needed, the support, and a lot of other things are not only expensive, in many states they are now illegal to own or make. Read some of the posts about that.

I need a 3 necked flask to make these, and in two states at least, they are illegal as are glass beakers.

As for digital equivalents to EIR, no, there are none. Digital can 'see' IR but cannot capture it with the shifted sensitivities (false color) that EIR could do.

OTOH at least some of the users here have done it. So it seems to work.

Yeah but you have an issue with sag. 4x5" is probably going to work better than 8x10" for example.

Something funny/cool just happened...I just decided I would check out eBay to see if there was any EIR on there and ended up being an auction that I won. As far as I can tell, I just won about 25-30 rolls of EIR and about 60 rolls of other random film all for less than the price of ONE roll of EIR! Yay stupid people selling off stuff and not knowing how to list on eBay!

That really seems a bargain.

But in case you have well kept (frozen) EIR to compare with, perhaps you can tell us how IR-sensitive those films are.

I'm not sure whether the sensitivity in such films just decreases in amplitude or whether the wavelenght maximum decreases, or both...

Though even if it fell down to that 750nm something as the low end IR-films it still should work with some additional CC-filtering.

Isn't that the case for all film??

I guess there is, but it depends on what properties you want to be equivalent. In many ways digital is a lot more suitable for false-colour infrared imaging than film is, particularly in technical applications.
