PhotographyUnderstanding the Exposure Triangle
Dustin Banyai
Exposure TriangleIncludes three settings
1. aperture2. shutter Speed3. ISO
ApertureControls how wide the lens opens
• Controls how much of the photo is in focus• large aperture= small focus area• small aperture= large focus area
Changing focus area can give the photo a sense of depth
Large Aperture Small Aperture
Shutter SpeedControls how long lens stays open
• Slow shutter speeds blur motion• creates sense of movement
• Fast shutter speeds freeze motion• captures detail
Fast Shutter Speed Slow Shutter Speed
ISOIncreases light sensitivity
• Lets us use faster shutter speeds in dark rooms• Image quality decreases as ISO increases
Image noise is preferable to an underexposed photo
Low ISO High ISO
ExposureHow much light the camera takes in
• Underexposed photos lose detail in dark areas
• Overexposed photos lose detail in light areas
• Properly exposed photos show detail evenly
Underexposed Properly Exposed Overexposed
Exposure TriangleEach setting effects how much light camera takes in
• When increasing shutter speed you have to increase aperture• When decreasing shutter speed you have to decrease
aperture
• When increasing ISO you need to decrease shutter speed and aperture.
