ON - CAMERA BOUNCE FLASH
The very convenience of portable flash is also its major drawback . These units are designed to be triggered from the camera position , attached to the camera body by a hot - shoe , and although this makes them easy to use and handle , it is hardly ever the best position for a main light . Being so close to the lens , there are virtually no shadows , and the result is often flat in appearance , with little in the way of modelling . An extra danger is the condition known as ' red - eye ' , in which light is reflected directly back from the retina of the person being photo- graphed .
All this comes from having the flash on the camera and pointing directly forward . There are some situations which can benefit from this notably subjects that have strong inherent colours and tones , but which are not shiny but more often than not it is better to move the flash or modify its output in some way .
Many on - camera flash units have swivelling heads that allow the light to be aimed upwards . The idea behind this is to bounce the light off a ceiling ; as most ceilings are white or lightly - coloured , the effect is to soften the illumination on the subject . At the same time , the amount of light is drastically reduced , and
Flash Outdoors
Without the use of flash , backlit subjects ( right ) can be recorded as silhouettes , since the average SLR's metering system will record the bright sky as the dominant light source . Fill - in flash quite literally ' fills in the details that have been lost in shadow .
A recent trend has been the appearance of SLRs with built - in flash units ( such as the Ricoh XR - X , shown top ) . which are designed both for convenience and to overcome the problem of red - eye . Bouncehead flashguns ( such as the Ricoh Speedlight 300P ) are commonly available , and are generally more powerful than built - in units .
you should be careful to watch for the under - exposure warning light ( inside the viewfinder with a dedicated unit ) . In a typical domestic room , the ceiling will be about 10ft ( 3m ) high and , if it is painted white , the loss of illumination should be in the order of about two stops . Remember , however , that for the metering to work , the sensor must be taking its reading from the subject rather than from the ceiling . So , unless the flash offers TTL metering , make sure that the sensor does not also swivel upwards .
To a limited degree , it may be possible to diffuse the flash . Some units have attachments available that act as reflectors : the flash is swivelled to aim up into white card . For others , an over - sized head can be attached with a translucent diffusing ' window ' .
BELOW Bouncing flashlight off a suitably reflective surface can give results that are devoid of the harsh shadows that are a characteristic of direct flashlight . The loss of illumination in the average domestic room with a white , 10ft of two stops , and this should be taken into account when calculating exposure .
