Sony solves the common problem of excessive flash with Face Detection technology. (Sample photos for illustration purposes.)

features

Face Detection

Taking advantage of the BIONZ

™

integrated

circuit, Sony cameras accurately recognize

– and apply appropriate flash to – the

human face.

Even a simple snapshot can

trip up the flash system of a

conventional camera. For example,

faces can easily become bleached out

because the flash was too strong. Sony's

BIONZ

™

processor solves this problem with

Face Detection. As you shoot, the Face

Detection function actually analyzes the data

that make up your digital picture. In this

way, Face Detection can identify and track

up to eight faces at a time. Then the camera

automatically adjusts for optimum focus,

exposure, flash and even white balance

on the faces themselves. The result is far

more "good" pictures, far fewer rejects

and re-takes.

and the BIONZ processor, please turn to

TTL Pre-Flash Metering

Unlike other digital cameras, which only

"guess" at flash exposures, Sony actually

measures the flash output and adjusts

accordingly.

When it comes to flash photography, most

auto exposure systems are flying "blind."

They can only guess at flash levels because

they can't measure the scene as it is lit by

the flash. Sony demanded a better way, called

Through-the-Lens Pre-Flash Metering.

Step One: The Sony system fires a

momentary pre-flash onto your subject.

Step Two: The system instantly reads the

resulting light through the camera's lens,

and off the camera's CCD image sensor.
