Firstly to say im an amateur is a grossly proportioned understatement! I have an old canon T70 that my dad gave me a couple of years ago. Ive messed around a bit. Bought a few bits and pieces because it pleased me. But now im becoming a bit more interested in various techniques. I discovered IR on saturday, raced out of the house sunday and bought a roll of KODAK HIE and a HOYA R72 filter! Unfortunately i havnt got a clue what to do becasue: Ive looked on different sites and there seems to be a lot of conflicting advice on exposing the film. Is there any general rule of thumb? Or do i learn the hard (and expensive) way - going through about 5 rolls before i get it right? Any info on which ISO, how to meter, anything will be greatly received. Ta.
