OCR: F2.8 F5.6 F11 F22 1/500 th. 1/125 th. 1/30 th. 1/8 th The above diagram gives some idea of the Tink between aperture and shutter speed. Each of the above combinations delivers exactly the same amount of light to the film as the others, 1/500th for, but the pictures will be very different. Using result say a shot of a motor bike at speed, would in a sharp bike but a blurred background due to the limited depth of field at F2.8. It is depth of field at any given aperture will be greater on a also the case that the wide angle lens than on a telephoto. Depth of field also reduces as the subject gets closer - thus the D of F. on a 28 mm_focused at 10 feet and F8 might reach to infinity - on a 300mm, it may be only a few inches ! At the other extreme, the camera could be on a tripod and 1/8 th used to shoot a still life, The F22 aperture would result in a considerable D of F. as required for such sub jects .
