1. the process of capturing light with your camera to produce an image on a digital sensor

1.1. Shutter

1.1.1. Controls AMOUNT of light that enters camera by the length of time it stays open

1.1.2. The longer the shutter stays open the more light enters the camera

1.1.2.1. Shutter opens and closes at different speeds

1.1.2.1.1. 1/2000 1/1500 1/1000 1/750 1/500 1/350 1/250 1/180 1/125 1/90 1/60 1/45 1/30

1.1.2.1.2. Also known as "stops"

1.1.2.1.3. fraction of a second

1.1.2.2. Slower the shutter speed the more light will enter the camera

1.1.2.2.1. Motion Blur

1.1.2.3. Faster the shutter speed, less light will enter the camera

1.1.2.3.1. Freezing Motion

1.2. Aperture

1.2.1. Controls the BRIGHTNESS of the light that enters the camera

1.2.2. Works like the pupil of an eye, contracting or expanding

1.2.3. Also known as "f-stops"

1.2.4. Aperture Openings

1.2.5. To change aperture hold down the AV button and turn the main dial

1.2.6. Main Dial

1.3. High ISO creates digital noise

1.4. ISO

1.4.1. Sensitivity to light

1.4.2. Higher ISO number = Less light is needed

1.4.2.1. Digital noise will be most prominent in shadows or low light situations

1.4.3. Lower ISO number = More light is needed

1.4.4. to be safe don't go above 1600 ISO

1.5. Light Meter

1.5.1. activated by pressing shutter button half-way

1.5.2. Untitled

1.5.3. Shutter and Aperture are changed until bar blinks under zero

1.5.4. PO#1 - Motion In-class exercise

1.5.4.1. Shoot a variety of photos that contain both blurry and frozen motion

1.5.4.2. Shoot a minimum of 20 blurry and 20 frozen

1.5.4.3. Make sure all images are shot as JPGs

1.5.4.4. Set "White Balance" to AUTO

1.5.4.5. Keep camera on Manual mode

1.5.4.6. No automatic focus
