In the past I've primarily used my tripod as a means to make long exposures that are not possible to hold steady hand held. I know when doing landscape photography I should really use the tripod as a means to shoot at ISO 100 at my DOF chosen aperture regardless of lighting levels.

I think I am probably missing out by my photography being 98% hand held. I'm planning to use the tripod more for upcoming photography.

I was curious for the forum members:

a) What types of images do you use your tripod for?
b) For what percent of your photography do you use a tripod?
c) For those of you who have 50%+ tripod use, how heavy is your tripod/head rig?

Thank you
Dave
