Action Notes (140-149)

Flashes for Action Photography
• Electronic flashes are a good way to stop or freeze action
• Harold Edgerton used one to freeze the kind of subjects he photographed
• Most cameras made since 1980s are designed for use with an automatic flash called Through the Lens (TTL), flash
• Flash does not go on when there is enough light exposure to the camera
• Older manual cameras use manual flashed with dial on the back that lets you set the ISO of the film you’re using
• Far away subjects
o Wide-open f-stop
• Close subjects
o Stopped-down f-stop
• Drawback in using a flash to stop action is the flash’s range
• Built in flashes are only effective up to about 10 feet
Camera Support
• Action photography consider using a tripod
• Monopod
o One tripod leg that mounts the camera up and down movements
o Many sports photography use monopod
Freezing the Action
• Freez action
o To capture the moving subject as a stationary object with no blurring
 Done by using a fast shutter speed with a fast film
• Faster shutter speed=sharper image
• Stopping action use faster ISO film
• Photography inside
o Faster film or higher ISO setting on digital camera
• Visual noise
o Looks like red, green, blue speaks in the image
o Makes image look grainy and coarse
o Higher ISO more visual noise
Blurring the Subject
• Blurring Subject
o Use slow shutter speed without moving the camera
 Also called subject motion blur
o Longer shutter is open more movement is caught
o Use slow shutter speed in sun light
Types of Blur
1. Camera motion blur
2. Subject motion blur
3. Out-of-focus blur
4. Depth-of-field blur
Panning
• When using slower shutter speeds, the subject can become so blurred that it is unrecognizable
• Panning
o Using a slower shutter speed while moving the camera to follow the subject
• Printing
o 35mm are to small
o 8x10 are perfect
