With an IR filter in front of the lens, and a normal IR cut filter on the sensor, yes foliage turns pink (some reds get through 720nm filters). Everything has a red and pink color to it.
When you remove the IR cut filter from the sensor, it is seeing IR and visible at the same time, so colors are all kinds of shifted. It all depends on how much IR reflectivity different materials have. On Sat, Aug 10, 2013 at 8:41 PM, Zos Xavius <[email protected]> wrote: > are these all with a filter?
