Shooting using a tripod in tight spaces little tricky. If you're doing work on a tabletop with a camera weighing less than three pounds, consider using this tabletop monopod from Sharpics for $50. It connects to the top of your table so you have more room to move around. You can still easily pan or tilt (up to a 115 degree angle) with the ball head and tilt knob. The monopod can extend up to inches, with a two-part column that collapses.
