3.2 Flash Modes
The Speedlite EL-100 offers various flash modes for different shooting scenarios:
- Auto (A): The Speedlite automatically sets the optimal flash output based on camera metering. This is suitable for general photography.
- Manual (M): Allows you to manually set the flash output level. Refer to your camera's manual for specific settings.
- Optical Wireless (Sender/Receiver): The EL-100 can function as both a sender and a receiver in an optical wireless flash system.
- Sender: Use this mode to trigger other compatible Speedlites wirelessly.
- Receiver: Use this mode when the EL-100 is being triggered by another Speedlite or a camera with a built-in optical transmitter. Select the appropriate channel (1-4 Ch) to match the sender unit.
3.3 Bounce Flash
The Speedlite EL-100's flash head can be rotated horizontally and tilted upward to allow for bounce flash photography. Bouncing the flash off a ceiling or wall can create softer, more natural-looking illumination by diffusing the light.
- Upward Tilt: The flash head can be tilted upwards to various angles (e.g., 45°, 60°, 75°, 90°).
- Horizontal Rotation: The flash head can be rotated left and right.
