S2 Mode: Slave Flash Operation (Auto Trigger)
S2 mode on the Sunpak DF4000U also operates as a slave flash, but differs from S1 in its triggering mechanism. S2 responds to the pre-flash emitted by cameras utilizing automatic exposure (TTL) flash modes. This pre-flash measures the light and then the main flash fires shortly after. The DF4000U detects this pre-flash and waits for the subsequent main flash to trigger.
This mode is beneficial when working with photographers using TTL flash systems. However, it’s crucial to understand that S2 can be unreliable if other automatic flashes are present, potentially triggering prematurely. Ensure the triggering camera is set to a TTL auto mode for S2 to function correctly, providing a convenient wireless flash solution.
TTL Mode: Automatic Exposure
TTL (Through-The-Lens) mode on the Sunpak DF4000U offers automatic exposure control, simplifying flash photography. When used with a compatible camera, the flash communicates with the camera’s metering system to determine the optimal flash power. This eliminates the need for manual power adjustments, ensuring properly exposed images in various lighting conditions.
To utilize TTL, ensure both the flash and camera are set to TTL mode. The camera will emit a pre-flash to measure the scene’s light, and the DF4000U will automatically adjust its output accordingly. This mode is ideal for fast-paced shooting situations where precise exposure control is needed without constant manual adjustments.
