4. Operating Modes
The RF1-C offers three primary flash modes to suit various photographic needs:
- TTL Mode (Through The Lens): This mode automatically determines the correct flash exposure by measuring the light through the camera lens. It supports exposure compensation, exposure bracketing, and flash lock for precise control.
- M Mode (Manual): In Manual mode, you can manually adjust the flash output from 1/1 (full power) to 1/128 power. This provides complete control over the flash intensity, allowing for fine-tuning based on ambient light conditions and desired effects.
- MULTI Mode (Stroboscopic): This mode allows for creative stroboscopic flashes, firing multiple flashes during a single exposure to capture a sequence of movements.
The A/B flash tubes can be controlled independently or collectively. In TTL/M modes, the flash ratio is adjustable from 8:1 to 1:1 to 1:8 in 1/2 stop increments, enabling fine-tuning of image contrast and directional lighting.
4.1 Assist Focus Lights
The flash unit includes two assist focus lights to aid in quick focusing in low-light conditions. These lights help the camera's autofocus system achieve accurate focus before the main flash fires.
