Hello. I shoot a lot of 35mm Infrared Film. I mostly shoot Ilford SFX 200, and am satisfied with the IR effect, even though it is not truly IR film. I have a few rolls of Efke IR820, and would like to shoot them before all of the leaves disappear completely. Does anybody know if Ilford ID-11 developer will work with Efke IR820? I have a large amount of the Ilford developer, and would prefer not to have to buy a different developer.
