Effect of flash light I want to know about the effect of flash light on the exposure of a film. In sufficient or somewhat less light the automatic cameras sets the apperture and shutter speed to get a correct exposure while in manual cameras you can set it in order to get a correct exposure. But a flash is an additional light which is not used when you or the camera set the apperture and shutter speed for correct exposure. Does this extra light overexposes the film ? Infact, it is suggested that you should use light even in sufficient light condition. Then what is the use of getting correct exposure with the available light when your flash is going to overexpose your film. And how much does it overexposes, if it ever does so ?

If everything is working correctly a flash does not overexpose the film. Automatic flashes shut themselves off when they have given enough light for a proper exposure. The flash (camera) meters the scene and fires the flash. The flash lights up for a period of time sufficient to make a correct exposure. We're talking fractions of seconds here so it is hardly perceptable to the eye.

Hi, sajeev. If you mean how is it when I use flash the addition of this light should overexpose my photo.When you switch on your flash look what happens to the exposure information on your camera.The camera alters the exposure to accomadate the flash. Look at your exposure with flash switched on then off. Hope this helps. regards,Roland.

Thanks a lot. I was really wondering what happens with additional light. I guessed the camera does the necessary things in order to get a proper exposure. Thanks a lot again.
