Shooting Functions

Shooting portraits with a flash in a dark environment often results in eyes
looking reddish in the photograph. This phenomenon, commonly known
as “Red-Eye”, is caused by the reflection of the electronic flash in the
retina of the eye. It can be reduced by taking a picture in brighter light or
by shooting with a wider-angle lens at a closer distance. When using an
external flash, it may also help to position the flash as far away from the
camera as possible.
As a rule of thumb, the distance for using the built-in flash (which varies
with the lens used) is within about four meters of the subject. (With
sensitivity 400)
The flash recommended indicator [b] in the viewfinder and on the LCD
panel will blink to recommend that you use the flash when you attempt to
take a picture in low light and backlight condition.
About Red-eye Phenomenon
Flash photography distance
• The flash effective range does not come closer than 0.7m (2.6ft), even if the
lens aperture is very small. The exposure will not be properly controlled when
taking a picture closer than 0.7m. Note that this can also cause and you will
see vignetting in the picture corners.
• To calculate the flash photography distance from the aperture size, see
p.139.
Flash Recommended indicator
• b will blink only in backlit conditions when the capture mode is set to b
(shutter priority) mode or a (manual exposure) mode.
• b stops blinking when the flash is fully charged.
• b will not appear in Bulb mode.
