So I know we haven't really got into talking about camera work yet with Maya but I thought this was tutorial really cool. It gives you a step by step on how to make the camera appear as though it is handheld or in a steadicam. Why is this relevant? He does it with dynamics instead of keying!
This approach is how they likely achieved some of these effects in those beginning scenes of "Wall-E" or the scenes with the snake in "Rango". Worth a look!
