Noteworthy Features in General                                 35


           film-based  SLRs!    (Figure  1-11.)    I  talk  about  Peaking  Level  in  greater
           detail in Section 6.7.

           1.2.7    FACE DETECTION

                                            In  addition  to  having  a  sophisticated
                                            exposure metering function that is not
                                            easily  fooled  by  difficult  light,  your
                                            camera  employs  face  detection  to
                                            determine which focusing point to use
                                            far  faster  than  was  previously
                                            possible.  Have a look at the example
                                            in Figure 1-12.

                                            Keep  in  mind  that  I  was  always  a
                                            “focus-lock-recompose-shoot” kind of
                                            guy,  which  is  just  completely
                                            incompatible  with  shooting  kids.
                                            Using Face Detection changed all that
                                            -- it will find the face, focus on it, bias
                                            the exposure for the face, and then it’s
                                            ready – all faster than my experienced
                                             skills could do.  It’s also much more
                                            accurate than the pure “wide-area AF”
            Figure  1-12:    Face  Detection  finds   method,  since  in  the  old  days  there
            the  subject  quickly  even  though   was  no  intelligent  scene  analysis
            other objects may be closer.   Had I
            used  the  focus-recompose-shoot   going on – the camera would usually
            method  I  would  have  missed  this   focus on whatever was closest.  Find
            shot.                           out  more  about  my  experiences  with
                                            this feature in Section 6.27.
