You are possibly using a non-corresponding developer to process your film. I can't offer you any other solutions as I am having difficulty knowing how long to develop IR film for ???? Could you help me answer this one. If I set the A>S>A> at 125 then how will that relate to the Developing time etc... I underastand if you don't have time to answer... Thanks; ferne millen

Mine have a purple tinge to them to, I think it is perfectly normal.

forgot to add, ferne, you need to supply more details.. are you talking about Konica IR750 as well or another IR film? Also, which developer?

One way around this problem is to use a 2 bath developer, Diafine in my case. Then all you need to do is some bracketing to determine your EI. Diafine works ok with IR films, but I have stopped using Konica 750 due to widely varying fog levels. MACO and HIE don't seem to have these fogging problems. Maco and Konica are pretty much alike, except for their response to 720nm and 25A filters.
