My science back ground starts asking all kinds of questions. It's clearly an energy thing. Emitted light energies ect. One way I would try to get a handle on it is to create some sort of gradation of substances and observe the effect. But I didn't think you were a scientist so that may not be you cup of tea. It may not be mine either! I think one problem you will encounter is that different plants may well bew colored different colors although they are at the same temperature. Because I gather that the IR filter is not actually temperature sensitive but Infra Red Energy dependent. OK. How about this can you photograph water, fruit juice, and rusty water. And wood, concrete, and plastic? Please, please, oh pretty please? I simply have to get me oine of those IR filter things!! Buy the way any ida how one develops IR film? Nplus, Alpha, somebody.

Bsteph, there are a lot of IR sites out there. Dealing with it digitally and in film seem to be pretty different. I'd do a search on google for infrared photography. I read a good site on film IR, but I didn't bookmark it. Think it was a link from one of the good digital IR info sites. If I find it again, I'll post it here. Diane

It is basicly the same process as normal b/w film. color IR is slide film, so you just take that to your favorite photo store. One note to beware of when doing your own....ALWAYS be sure to load and unload your camera in TOTAL darkness. Changing bags DO NOT WORK they let an unbelievable ammount of IR through. I havve the specifics of development of kodak IR, but you should be able to find the development times easy enough.

Just remembered something important.... the choice of developer also makes a HUGE difference in the contrast and grain in IR. For artistic purposes use D-76, for slightly higer contrast/grain use HC-110 (dil. B) for HIGH contrast scientific purposes use D-19. I have only used d-76, and hc 110..... I have seen work done with D-19 but do not reccommend it for pictoral purposes.
