    I haven’t quite understood ir conversions yet. Why is it the foliage and grass look different, but not the car, tree, or ground?

    Funcomposition, too.

      The chlorophyll in live foliage reflects infrared light strongly, so it appears bright in infrared photographs. (Or, in false color IR, it appears magenta/pink or whatever color is used to represent IR.)

      Infrared light can also have unpredictable interactions with paints, dyes, pigments, etc. resulting in printed designs appearing different. I have a long-running project photographing flags in infrared with widely varying results. IR is also more resistant to UV haze (since it’s at the other end of the near-visible spectrum) and can sometimes pass through sunglasses lenses.

      Other things will also look funky in IR, such as the sky (dark as with a deep red BW filter) and human skin and eyes.

      UV photography can get even funkier, but I haven’t gotten into that yet.
