Hi Colin!
That would be "no". An IR filter cuts most of the light EXCEPT the
IR... thus, in COLOUR mode, you get some the reds, more of the deep
reds and the IR, which shows as deep red. The photo shows exactly
what it should... a colour interpretation of the (mostly) IR
spectrum. It looks different from the colour version (without
filter) for exactly the same reasons that the B&W IR photo looks
different from the B&W version w/o the filter.
I included them all, so people could see just how much IR the M8
responds to. If I get some spare (ha!) time, I'll post some shots
from the same vantage point, made with the same lens and filter, using the DMR.
Cheers!
