The recent Canon short 'When You Find Me' has some cool shots done on a 5d modified for IR shooting. This got me wondering if I could do this on my Epic? Since the OLPFs are removeable, how hard would it be for there to be an OLPF that allowed all IR through? Maybe one that also had ND built in for this purpose? I'd heard rumors there were IR modified Red 1s, but it seems it'd be a breeze to do this for Epic.
