Nissin Di700A Flash for Micro Four Thirds Cameras - Manual (Page 18)

Fill-in flash and Light diffusing panel
For short distance or portrait flash photography, if the light is not
too sharp or too strong to the subject. Use fill-in reflector flash or
diffuse the light.
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 soften and creates a lively color effect
on the subject.
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.
