2. Key Features to Look For
Guide Number (GN):
- Definition: A measure of the flash’s power. The higher the guide number, the more powerful the flash.
- Importance: A higher GN allows you to illuminate subjects that are farther away.
TTL (Through The Lens) Metering:
- Definition: A system that measures the light coming through the lens to automatically adjust the flash output.
- Importance: Ensures correct exposure without manual adjustments.
Adjustable Power Settings:
- Definition: The ability to control the intensity of the flash output.
- Importance: Allows for more precise lighting control and can help in creating various lighting effects.
Swivel and Tilt Head:
- Definition: The flash head can be rotated or tilted to bounce light off walls or ceilings.
- Importance: Provides flexibility in directing light and reduces harsh shadows.
Wireless or Remote Triggering:
- Definition: Capability to trigger the flash remotely using wireless triggers or built-in radio transmitters.
- Importance: Ideal for off-camera flash setups and creative lighting.
Recycle Time:
- Definition: The time it takes for the flash to be ready for the next shot after firing.
