I thought putting my camera on a tripod and using the timed shot was a good trick for gadget close-ups, but this is tons more fun. Nikon’s Camera Control Pro ($79, 30 day trial available) lets you remotely control a compatible camera from your computer. I can’t figure out how to do a preview, but it’s still really helpful; it lets you do a lot more than just trigger the shutter. You have access to most of the configurable features of the camera.
Are there similar tools out there for other cameras? Let us know in the comments.
