Professional Photography Class

Balance the exposure triangle—aperture, ISO, and shutter speed—to prevent data loss in highlights and shadows. Set your camera to manual mode to practice controlling light and color.

Explore how aperture controls light and depth of field by adjusting f-stops, from wide open for blurry backgrounds to smaller openings for sharp, cinematic photographs.

Explore how shutter speed, defined by a fraction of a second, controls sensor exposure and motion: higher speeds freeze action, while lower speeds create blur after setting the aperture.

Explore how ISO completes the exposure triangle after selecting aperture and shutter speed. See examples that show noise at high ISO and the risk of overexposure.

Explore exposure modes, including auto and program, and learn how aperture priority, shutter priority, and manual modes use the exposure triangle to control ISO, shutter speed, and aperture.

Learn to use the exposure triangle by setting aperture for depth of field, then ISO, then shutter speed, with outdoor practice to create shallow or deep focus and freeze motion.

Discover how the exposure meter predicts whether a photo will be well exposed, underexposed, or overexposed, and how aperture and shutter speed affect it.

Matrix metering reduces exposure across the frame, spot metering reads exposure at a single spot, and center metering reads the middle, handy in varied light when the subject is centered.

Learn how white balance offsets lighting color to keep white, and grasp kelvin-based color temperature from warm 2500 to cool 10000 and its impact on scene colors.
