Why Use Flash in Photography?

Flash is a portable light source that can:

  • Add light to dark environments.
  • Eliminate harsh shadows in outdoor photography.
  • Freeze fast-moving subjects.
  • Add creative effects, such as dramatic highlights or silhouettes.

While natural light is ideal in many cases, flash gives you more control, letting you adjust intensity, direction, and quality of light.

Types of Flash

  • Built-in Flash: Found in most cameras, this small flash pops up when needed. While convenient, built-in flash has limited power and can produce harsh, direct lighting.
  • External Flash (Speedlights): External flashes are portable, attachable units that provide more power and flexibility than built-in flashes. They often include adjustable heads for bouncing light, and some can work wirelessly for off-camera lighting.
