Matrix TTL mode (other almost identical variations include the 3D and other modes) This mode is intended to balance flash with ambient light so long as there is enough ambient light. If you are in normal sync mode and the light gets too dim to make a good exposure at 1/60 sec the flash level is supposed to increase to provide a flash-only

(I am equating ambient light and continuous light saying all ambient is continuous and am only differentiating instantaneous flash). But flash is not affected by shutter speed . Flash is a near-instantaneous pulse possibly 1/1000 second duration or speedlights are perhaps much shorter but much faster than our shutter speed duration.
