[QUOTE]\nIn message <>,\n\n\nIt's not really all that uncommon a situation where you can do that. I\nhave taken many pictures with the EC set to +2 with no blown highlights\nresulting.\n\n\nIt's simply a matter of estimating contrast. If you see a reflection,\nfor example, in glass backed by something white, shooting at 0 EC is a\nhuge mistake. If you can't compromise DOF or shutter speed by "exposing\nto the right" at ISO 200, then go to ISO 800 and +2; you will have a\ncleaner RAW capture than if you did ISO 200 and 0 EC. Same concept\napplies in fog, or in a field right after sunset or under heavy clouds\nwhen no sky is in the image, etc. [/QUOTE]\n\nYour are talking about measurement errors. If you take a picture in fog,\nafer sunset, etc. that includes a white piece of paper you still need a\ncamera that is capable of capturing 100% reflectance. If is only when you are\ntaking pictures of dull gray objects that you can leave out one or more stops\nof head room.\n\nI can't see the point of a setting that cannot record 100% reflectance.
