Using the flash
Using the bounce light
By using the bounce light, you can take the images with less shadow as the light is
uniformly applied to the subject.
This product allows adjusting the flash head
in various angles (0-90°). In order to obtain
the most efficient flash effect, please set an appropriate angle of reflection.
900
•Please do not adjust the angle forcefully beyond
the adjustable range
of bounce light. It may
damage the product.
•When the angle
of reflection is not enough, the
flash contacts the subject directly and hence,
the light
is not applied evenly.
•The applicable range of light
is changed
according to the shooting conditions such as
the state of reflective surface and shooting
distance.
Please
check the image taken through the
camera screen upon taking the shot.
