Figure  11-10.—Inverse-square  law. LENS HOODS Lens  hoods,  or  shades,  are  used  to  keep  strong sunlight from striking the front of the lens obliquely. PHOTOGRAPHIC  LIGHTING LEARNING  OBJECTIVE:  Identify  the  basic theories  of  photographic  lighting  in  terms  of outdoor lighting, existing light and electronic flash lighting. Light   is   the   most   important   ingredient   in photography.  Light  makes  photography  possible  by reflecting   off   the   subject,   entering   the   camera   and exposing  the  film. Scientists tell us that light is produced in waves. In many respects the waves of light can be compared to sound  waves.  Sound  waves  vary  in  length  and  they register  as  different  pitches;  conversely,  light  waves register as different colors. The intensity of light determines the brightness of the  subject.  The  formula  that  determines  this  is  the inverse-square  law  (fig.  11-  10).  It  demonstrates  that light decreases as the square of the distance increases. Becoming familiar with this law will help you use light more effectively during photographic assignments. The  light  falling  upon  a  subject  from  a  source  is tilled  incident  light.   When  incident  light  strikes  a surface, it will change direction; this change is called reflection.  If  the  surface  is  smooth,  the  reflected  light  is said to be specular; however, if the surface is rough, the reflected light is diffused Most objects reflect back both types of light. Reflection is an important characteristic of light. It is how our eyes can see objects and how film acquires a latent image. In this section you will learn how to take pictures using  the  following  types  of  light: l   Outdoor l   Existing .  Electronic  flash OUTDOOR  LIGHTING Daylight and sunlight are not constant sources — they   change   hourly   with   the   weather,   seasons   and latitude. The changes in daylight can radically alter the apparent shapes, colors, tones and forms of a scene. The color of sunlight changes most rapidly at the extreme end of the day. Strong color changes also occur during storms,  haze  or  mist  and  on  blue  wintery  days.  The 11-11
