Definition

Noun: A portable electric lamp that produces a brief, intense flash of light. It is used to provide illumination when taking a photograph, especially in conditions where there is not enough natural or ambient light.

Usage

A flash lamp is a device used in photography. It is typically attached to or held near a camera. When a picture is taken, the lamp emits a very bright light for a very short duration (a flash) to illuminate the subject. This helps create a properly exposed photograph.

Examples

• Noun:
  • The photographer used a powerful flash lamp to capture the indoor ceremony.
  • For portrait photography, a diffuser is often placed over the flash lamp to soften the light.
  • Modern cameras often have a built-in flash lamp, but professionals usually prefer external ones.

Advanced Usage

• "To fire the flash lamp": To activate or trigger the flash lamp to produce light.
  • The flash lamp fired automatically because the room was too dark.
• "Flash lamp synchronization": The technical coordination between the camera's shutter opening and the instant the flash lamp emits light.
  • Proper flash lamp synchronization is crucial to avoid dark bands in the photo.
