Hi all, Do any of the more professional DSLRs (ideally a Nikon) allow you to auto bracket exposure in one direction only ie instead of three pics, for example: +1, normal and -1. Can any be programmed to do two brackets? For example: +1 and normal? I often find that, for example, when doing a landscape i don't need the +1. Or when doing birds in flight I don't need the -1.
