Nissin i400 TTL Flash for Cameras - Manual (Page 13)

Fill-in flash and Light diffusing panel and Soft box
For short distance or portrait flash photography, if the light is not too
sharp or too strong to the subject, use the fill-in reflector flash or
optional soft light box.
If the subject is close (within 2 meters), turn the flash head
90° upward and pull out the fill-in reflector as shown in the
picture.
Take a picture as usual. A blink of fill-in flash freshens up
the subject in natural image.
This technology is also useful to eliminate the shadow on
the subject under the tree.
For portrait photography, pull out the light diffusing panel
and place it over the flash window as shown in the
picture. The diffusing panel makes the flash light softer.
Since the light diffusing panel expands the lighting
area, it covers the range of 16mm focal length lens.
This small blink of flash is also useful when taking
a picture of a baby without scaring him.
