I will be trying for a sunrise tomorrow, first time ever. Since everything will be new to me, should bracketing be kept to one fixed variable for now, (ie iso for now), rather than trying to also bracket for shutter and aperture? Would it be too complicated trying too many variables for first time out? I am working with the IIn tomorrow, only because it has been my main body for the last few months, and I had forgotten alot of the 30d (although the crop will be nice for the siggy - but I can only carry so much)....and that camera can auto bracket for me.........
I will be working only with 2 lenses, the 120-300 and the 16-35, that is all I can handle with tripod, etc.
