Hello, I have got a question about the internal flash of the D40xbut could be on any camera (have been reading some things about flashes recently but still have a problem): if you take a picture, say, in Program mode, will the light meter be influenced if the flash is on or off? I have read that the light meter of the camera and the light meter of the flash are two different things, but is this only for external flashes? If the (internal) flash mode is on TTL (and not on Manual), then, does the camera choose the flash intensity or is it always the same and it adjusts the aperture/shutter speed? I have started reading Strobist, but I think Lightning 101 is only for external flashes (if I am not reading something over there...)... Thanks everyone for your answers!!
