I got a pinhole body cap and a Hoya R72 infrared filter that I can use with my Fuji S2, and played with them. All these shots are handheld, or at best supported on an environmental object that was handy. The pinhole shots are in the 4-16 second range of exposures, the infrared 1/2-4 seconds. I may have the focus off on the infrared, too; no focus confirmation or preview with a digital SLR. Still, they show promise for the techniques.
