Some tripots let you take the central pole out and stick it back in upside down. Then you place the legs straddling the target and ... If you can't do that, it might work to make one leg (much) longer so the tripod is tipped on its side holding the camera out away from the two close in legs. You would probably have to place a weight on the long leg to keep it from tipping over. -- These are my opinions, not necessarily my employer's. I hate spam.

For just a tripod with a good swivel/tilt head, I bought a cheap spirit level with laser line projector for �5 in a dicount store, its no more than DIY stores charge for just a spirit level and the screw fitting fits my camera (and webcam). So far I've used the spirit level a few times but the tripod now lives with my camera and I've yet to use the laser projector.

But the central pole won't come out :-( But it might work to get another tripod head and figure out how to mount it to the pole slide. > >If you can't do that, it might work to make one leg (much) >longer so the tripod is tipped on its side holding the camera >out away from the two close in legs.
