Took out the "IR Chrome" setup (faux aerochrome) yesterday and found a new favorite subject: astroturf. As someone who takes IR photos a lot, I cannot overstate how funny it is to see "grass" looking normal.
This is getting to one of the historical roots of infrared photography: military surveillance. The reason why Kodak's color IR film was called aerochrome is that it was used for aerial surveillance to identify real live foliage versus fake vegetation or dead stuff being used to cover things. Less militarily, aerial imaging is also used for agricultural science. See here for the modern incarnation.
Astrotruf is not a common material here in yards, so I'll need to figure out where I can find some more. @vossbrink suggested the south bay or school athletic fields.
