Flash

ISO is used when its bright outside, it is a film speed and it is sensitive to the film and pixels are to light. Flash made our subject pop out so we can see them and the ISO were dark but u can see the light in the background. It shows the orange or greyer on the pictures. The more higher the ISO gets it seems to get lighter but it still shows the grey in the picture but does not show the darkness to where we can not see our subject. Using ISO over flash will show the other stuff that surrounds the subject just like the lights when you use flash it loses all that light. Moving while using a fast ISO it catches the blur in the picture.
