Great idea."how to's", camera and software recommendations could be posted.
For starters my most important discovery is the Casio EXF100 camera. A regular digital camera that happens to shoot very clear video in super slo motion. 240 frames per second compared to the standard 30 frames per second. It can be found for under $250 and allows you to see slow motion video including blurless bats and arms when pitching. AWESOME!
