I'm still learning to use my new XSi (my first DSLR,wih the kit lens) and so far I've taken some OK shots, and quite a few that aren't. I'm going to an Air Show this Saturday and was wondering what settings people would suggest to capture fast moving subjects, such as airplanes in flight. I've been viewing a LOT of tutorials for this camera on You Tube (personally I find them much more informative than cramming the instruction manual) but so far I haven't been able to find one in regards to action shots (sports, etc). Any suggestions are greatly appreciated!
