Splutter! There is no such thing as correct exposure, except the exposure 
which gives the result you want! Photographers have been exploiting 
different parts of the curve for aeons in order to control tonal 
relationships for a given aesthetic result. In it's most evolved form, 
that's what the Zone System is all about.

Amending exposure to be different from a grey-card value ain't a bodge, 
unless it's a mistake (in which case it is 'latitude' :0)
