Is the lighting "hard" (creating deep shadows) or "soft" (even and diffused)?
Indicates light sensitivity. High ISO (e.g., 3200+) is used in low light but often introduces "noise" or graininess into the image.
Controls motion. Fast speeds (1/1000s) freeze action, while slow speeds (1/30s or slower) can create intentional motion blur or unintentional camera shake. 2. Compositional Analysis
