I need some guidance - I've been using ML on T3i with Dual ISO pretty much ever sine it was released and had really good results.
I've since upgraded to a 5D3 (Merry Christmas to myself

) with latest nightly build and the field is a bit different in that I set the base ISO via the Canon menu, and then teh secondary one via ML, which is fine, I got that part.
What I *am* a little confused about is, how exactly to set this based on my shooting style. I have learned you can use the +/- EV settings to couple with automatic ISO mode which seems very handy. In practice on editing the files though, I am not getting near the results and dynamic range I was on the T3i shooting say 100/800 and then manually under exposing a stop to get color and clouds in the sky in addition to well lighted scenery-this is basically my intended end use.
I have the 5D3 set to -3EV and I just can't seem to duplicate my previous results, I can't bring out the highlights.
If anyone can help me fully understand the menu choices and usage of this, I'd like to help write a small guide for other poor souls like myself
