2. Set the exposure settings you want to use on your camera. The highest shutter speed available will be
your camera’s ash sync speed. To use higher shutter speeds, switch to automatic TTL mode and activate
high-speed sync (see Using High-Speed Sync on page 18).
3. Take a test shot, and check the exposure on your camera’s LCD.
4. Adjust your camera’s exposure settings and the light output level of the ash as needed.
5. Press your camera’s shutter-release button to take the picture.
Note: For best results, a handheld light meter is recommended when using the manual ash mode.
Important! To avoid overheating and damaging your ash unit, please wait for at least 10 minutes after 20
continuous ashes at full power. The ash will automatically shut off if it gets overheated.
Controlling Flash Coverage (Zoom)
The VS-570N’s angle of coverage can be adjusted (“zoomed”) to match the focal length of your lens, so that
your image is evenly illuminated from edge to edge.
When the ash zoom setting is adjusted, the position of the reectors inside the ash head shift in order to
make the angle of coverage wider or narrower.
