flash is not just for night or low light image. it can also made for day light. Why? and for what? it's the question for beginner that just know about the flash usage. The function of flash is to get ideal exposure of the image you want to capture, sometimes you will get a dark or low exposure of image if you focus your camera shutter to get great background image. or we also know it as back light effect.
just take image at a day light, with a great sun light.. put your object cover up the sun. set your flash output to get an ideal shot. lock your focus and take some picture.
