Camera Exposure por Mind Map: Camera Exposure

1. The "Exposure Triangle"

1.1. exposure determines how light or dark an image will appear when it's been captured by your camera

1.1.1. too little light = underexposed too much light = overexposed

2. Aperture

2.1. controls the area over which light can enter your camera

2.1.1. also affects depth of field

2.1.1.1. the lower the f-stop value, the shallower the depth of field

2.2. a greater aperture range provides for more creative flexibility

2.3. controls the area over which light can pass through your camera lens

2.4. area of the opening increases as the f-stop decreases.

2.4.1. every time the f-stop value halves, the light-collecting area quadruples

2.5. Aperture Priority (Av or A) allows you to specify the aperture & ISO; one of the "creative modes"/"auto exposure (AE) modes"

3. ISO

3.1. controls the duration of the exposure

3.1.1. also affects image noise

3.2. determines how sensitive the camera is to incoming light

3.3. higher ISO speeds dramatically increase image noise; lower ones almost always desired

4. Shutter Speed

4.1. controls the sensitivity of your camera's sensor to a given amount of light

4.1.1. also affects motion blur

4.2. "shutter speed" and "exposure time" are interchangeable terms

4.3. specifically refers to how long incoming light from the camera lens is permitted to enter the camera.

4.4. can freeze or exaggerate the appearance of motion

4.5. Shutter Priority (Tv) allows you to specify the shutter speed & ISO; one of the "creative modes"/"auto exposure (AE) modes"

5. Manual Mode (M) - allows the specification of the aperture, ISO and shutter speed; one of the "creative modes"/"auto exposure (AE) modes"
