Step 4: Photographing in IR
Some of the best things to shoot in IR are plants. They reflect IR very well. The color of the film will come through in your IR pictures, so shooting in black and white makes for great pictures in IR.
Above are some examples of things photographed with this IR filter on my HTC Rezound. The first is a 60w equivalent daylight CFL, and the second is outside on a cloudless day at about 2pm. You can see how much light you lose putting the filter on, so remember to shoot with as much light as you can. I didn't bother doing any post-processing with these pics, but a little touch up can definitely help.
