I am very interested in the IR stuff. I understand the P41's, that have been so popular in homebrews lately, don't perform that well with an IR modification. I think you need a setup with a slave flash for an IR conversion. I have not looked into it very far but when you get a picture or two of a nice deer and then never see it again it make me wonder if I am moving them off with the white flash. Then there is the visibility of the white flash to others near by when it gets trigger by something. Sooner or later, I am afraid, the flash will give away my camera location to a thief.
