Basic terms in photography
1) Aperture The aperture is the adjustable opening in the lens that controls the amount (volume) of light hitting the camera sensor. . Measurement: Measured in f-stops (e.g., f28,f/11). . Effect: A lower f-number (f/2.8) means a wider opening, letting in more light and creating a shallow depth of field (blurry background). A higher f-number (/16) means a narrower opening, letting in less light and creating a deep depth of field (sharp background). 2) Shutter Speed Shutter speed is the duration of time the camera's sensor iS exposed to light. S . easurement: Measured in seconds or fractions of a second (e.g., 1/200s, 2s). . Effect: ‣ Exposure: Controls the length of time light hits the sensor. Longer speeds allow more light. 2 + • Motion: A fast speed (1/1000s) freezes motion, and a slow speed (e.g., 1/2s) blurs motion, creating streaks or silky water effects. 3) ISO ISO is the sensitivity of your camera's sensor to light. S . Measurement: Measured numerically (e.g, 100, 400,...
