GETTING THE RIGHT AMOUNT OF LIGHT TO MAKE THE PICTURE
2
Aperture Film Speed Shutter Speed Photography’s creative tools include: Photographer must decide which one takes priority.
3
Aperture most important for depth of field Shutter Speed most important for action – show motion or stop action Film Speed speed used allows for different aperture/speed combinations to provide a variety of creative effects
4
Which element you choose as a priority will be the most important decision you make before taking a photograph. next
5
aperture takes priority over shutter speed when depth of field is most important to the composition depth of field is the area of sharpness within a picture large shallow f stop is the diameter of the aperture expressed as a ratio of the focal length (ex)ex f/4 is one-fourth of the focal length ex: f/4 for a 100 mm lens, 100/4 = 25 each stop is ½ of the previous next

aperture larger #(smaller hole), greater DoF smaller #(larger hole), shallower DoF focal length short lens, greater DoF long lens, shallower DoF distance to subject farther, greater DoF closer, shallower DoF
10
Story telling has a beginning, middle and end large DoF use small aperture – f/16, f/22, f/32 use normal (50 MM) or wide angle lens (16 mm, 28 mm) have something in foreground, middle and background farther away (examples) next

14
Isolation a single theme or subject shallow DoF use large aperture (f/1.4 to f/4) shoot closer to subject use longer lens (100 mm or more) or macro lens (examples) next

17
Who Cares all items are the same distance from camera - no distant background or noticeable foreground use medium DoF – f/8 most recommended use about 50 - 100 mm lens (examples)
