Hi,
Usually I am about as shaky as the pope, on my SLR I can just manage the shutterspeed=1/focal length rule.
Yesterday evening I was taking some shots of a concert, and found myself in need of some longer shutterspeeds. I tried a method I once read on an other website, and it worked great!!! I took sharp, handheld shots at 1/15 sec and 1/20 sec, something I never managed before.

Sharp, insn't it? And that for Tv=1/20 Av=2.5 ISO=50 Focal Length=15.8mm :)
So how does it work? Set your camera to continues shooting, shoot 5-7 consecutive photos and select the best one. The theory is that when the camera shakes, its movement is approximately periodical and you have points of zero and maximum speed. So if you shoot series of pictures probably one or more will be shot during the moment when the speed is zero. Mind that this is not the same as shooting 5 seperate shots, in that case you always shoot at the same moment in the periodical movement (because the movement is partially caused by pressing the shutter) .
For selecting the sharpest shot you don't have to studie every shot on your monitor, just look at the (jpeg) file-size. The largest file will be your sharpest shot.
