I wonder whether this would be possible to use any picture's taken EXIF data as a template to the camera? I mean the ISO value, WB settings (temperature, offsets), expo etc. (maybe with image format/size too).

I see two usecases:

1. easy coming back from experimenting/changed conditions to user's favourite/casual settings (or after lending device to someone else or making any change by mistake),

2. adjusting settings for current scene - I sometimes find myself shoting a few photos with different settings just to choose the best one (mainly alternating WB as the 500D's auto isn't too good).

I realize these scenarios are not what pros do (like lending the camera or shoting blindly to find best values - especially for WB settings that don't matter in raw), but maybe this would be useful.
