Very, very cool. Thank you for posting this. I have a camera loaded with my 2nd roll of sfx with an IR72 filter and will develop with D-76 1:1. It helps a lot to see what somebody else did! I have tried to follow a recommendation to shoot one frame with no filter at iso 200 and then shoot 3-4 frames with +4,5,6,7 stops. How many stops from iso 200 is this?
@pbromaghin If I understand your question correctly I think you need to know what ISO you should set your camera to when using the R72 filter. If this is the case I would say you should set your film speed to 3 ISO. You will need your tripod and shoot on sunny days for best results.
