One Manfrotto 190XDB with Manfrotto heavy-duty 3-axis head,
One Focal tripod from the sixties in silver and hammertone grey,
One Tamrac Zipshot, self-erecting travel tripod (I love that thing!)
One tiny, less-than-a-foot-tall table-top tripod (so cute)
One really, really tiny three-spindly-bendy-legs tripods for a P&S digital
One clamp that also has 3 very basic legs that can fold out.
Those are the tripods.
For weird stuff, I have the clamp, and I also have a tripod head that clamps to a car window.
No monopods, but I do have a broken Velbon video tripod with no head I use as a light stand, and a proper light stand that came with a reflector.
So that's somewhere between six and eight.
As for the ones I use, it's pretty much the Manfrotto for Large Format or precision work, and the ZipShot most other times. The ZS gets toted along more often because I don't have to specifically think to bring it.
