Just got my new Canon 100m Macro for my Rebel XT this afternoon and just playing with it a little, it seems very unforgiving (i.e. extremely tight DoF) while wide open...so I'm just wondering if there are any tip/tricks the pros here have for holding a camera extremely steady (other that using a mono/tripod)? Do I need to start working out my arms? Take a meditation class? Do chill out and stop trying to take pictures of baby spiders on my first shoot? Thanks in advance.
