almost, but not exactly. Centre-weighted gives more emphasis to the centre, say 9.5% of the frame. Spot metering gives total emphasis to the centre (typically a smaller area than centre-weighted) of the frame.
if i want the pic to look brighter must use wat type of metering?
using center-weighted or the usual evaluative metering should give a brighter picture, but the sun will look very very bright. Or alternatively, up the EV.
