Mostly I try not to use a flash unless absolutely needed. The built in flash tends to screw up picture quality with adding way too much light to the subject. Hence I bought a separate flash sb 700. Now the problem that I am running into is how to make sure that when the flash is used, the right amount of lighting is (it's not over exposed) as the lighting meter in the camera doesn't account for the flash's mope satin when metering? Mostly I use iTTL mode.
