18. » Your camera’s white balance control helps you to make sure
that things that are supposed to be white actually look white
in your final image. Different sources of light create different
colour ‘casts’ – for instance, candlelight creates an orange
glow, whereas twilight can give everything a cool, blue hue.
» Our vision compensates for different types of light, so we see
that a sheet of white paper is white, whether it’s viewed by
candlelight or in twilight. The camera doesn’t; it records
what’s in front of it, which can lead to pictures that are too
‘warm’ or too ‘cool’
19. » There’s a range of white balance options open to
you, and choosing the right one can be a bit daunting
at first. Luckily, the default Automatic White Balance
(AWB) setting does a good job of getting the colour
of your shots right in most situations.
20. » Most SLRs offer Tungsten or Incandescent (light bulb
symbol), Daylight (sun), Shade (house), Cloudy
(cloud) and Flash (lightning). There might be one or
more Fluorescent settings (bar with lines) too
21. LESSON TASK
» Experiment with different types of light around the school.
Aim to capture at least three different light sources
» Demonstrate the different colours that they give off. Also look
for places where there are different light sources in the same
place.
LESSON TASK PART 2
» Experiment with the different white balance settings on your
camera. Take at least two photographs for each setting
» Download and label all images taken
