Exposure
________________________________________________________________________________________________________________________

  • An exposure reading is taken by pointing the camera at the subject while looking through the viewfinder.
  • The build-in meter measures the light being reflected back from the subject to determine the correct exposure rehired.
  • Then set the aperture and shutter speed combinations accordingly.


There are 4 factors that need to be taken into account when determine the correct exposure for a picture
THE LIGHT LEVEL

____________________

THE FILM SPEED

____________________
THE APERTURE



​____________________
THE SHUTTER SPEED


A lot of light  ................................................................................................  brief exposure
Low light   .....................................................................................................  longer exposure

_____________________________________________________________________________________________

Slow speed  .................................................................................................  long exposure
Fast speed  ..................................................................................................  short exposure

_____________________________________________________________________________________________
CONTROLS THE AMOUNT OF LIGHT TO THE FILM
eg f/8  .......................................................................................  half as much light as f/5.6
                                                                                           twice as much as f/11

_____________________________________________________________________________________________
CONTROLS THE LENGTH OF TIME THE LIGHT PASSES THROUGH THE LENS TO THE FILM
eg 1/60 sec  .............................................................................  half as much light as 1/30
                                                                                            twice as much as 1.125

  • Before taking a picture, measure the light levels - this may be done automatically.
  • The aperture and the shutter speed produce the exposure.  These can be used in various combinations to get exactly the same amount of light to the film.
