I went through a big IR phase. I loved the idea of photographing light which I could not see. I felt like I discovered a hidden world and wanted to keep exploring it. At the time I was also in a dark and depressing mood, and IR gave me a great way to express it. It's very addictive film once you get to know it. I also pulled of some shots with it I could not have gotten otherwise. For example dark green lilipads in a water bog would not show up with standard film, but IR they would glow white surrounded by the black water.
IR can be almost like conventional film yet subtly different-you can give reality a little bit more of a twist, make your pictures more otherworldly. The Kodak can be a bit over the top (depending on how you treat it) but the Konica is much more subtle. Look forward to trying Maco.
