I'm trying to figure out if and how it would be possible to bracket a shot at 0 and +4 EV with my E-PL1 - this is to blend the shots in post to reduce noise in shadows (further detail). I accomplish this with my 550D by setting exposure compensation at +2 EV and bracketing to 0, -2 and +2 EV - this yields 0, +2 and +4 EV brackets, the +2 is thrown away. Unfortunately E-PL1 only brackets up to 1 stop. Exposure compensation also goes only to +3 EV. Is there a way to quickly accomplish 0 and +4 EV brackets with E-PL1?
