Photos shot with full frontal flash are easily recognized by their harsh, dense shadows. This is often associated with a sharp drop of light from the fore- ground to the background.

￿This phenomenon can be avoided with bounce flash because the diffused light will produce a soft and uniform rendition of both the subject and the

background. For this purpose the reflector is turned in such a manner that the flash is bounced off a suitable reflective surface (e.g. ceiling or walls of a room).

The reflector can be turned vertically and horizontally. The vertical lock-in positions for bounce flash are:

• 60°, 75° and 90° (simply tilt the reflector to the required angle)

The flash head can be swivelled horizontally through 270°, and locks into position at 60°, 90°, and 180°.

The distance values on the LC display disappear as soon as the reflector is tilted upwards or the flash head turned horizontally. The distance from the flashgun to the ceiling or wall and from there to the subject is now an unknown factor.

When turning the reflector , or flash head, it is essential to ensure that it is moved by a sufficiently wide angle so that direct light can no longer fall on the subject. Therefore, always turn the reflector or head at least to the first lock-in position.

The diffused light bounced back from the reflective surfaces results in a soft illu- mination of the subject.

￿

The reflecting surface must be white or have a neutral colour and it must not

be structured (e.g. wooden beams in a ceiling), as these might cast shadows.

 

For colour effects just select reflective surfaces in the desired colour.

Use of the secondary reflector

is advantageous to avoid disturbing dense

shadows with bounce flash, for instance under the nose and in the eye sockets, in portraiture.
