    Can someone please explain what is happening during live composite exposure?

    As I understand it, an aperture value is set, and a shutter speed is determined in the composite settings. When the shutter is pressed, successive images are taken at the same exposure setting but only the 'light' portions are recorded?

    Does this mean it is only really useful for moving lights etc?

    Thanks in advance.

    I if remember it correctly you choose aperture and shutter speed (pressing info or something like that) and a first shot is taken to determine the "reference exposure".

    Then, during the actual shot, the photo is composed never "over-exposing" behind the brightest parts of the reference shot. You'll see that bright parts will stop as soon as they reach the reference exposure, while others will keep getting brighter matching the previous ones.

    This is what I remember from a few experiments I did.
