It’s represented as a
triangle because if you
change 1 setting, the
others will need to be
compensated

• Amount of light let into
the camera
• Do you want a single
object in focus or an
entire scene?

Think of a window. The
larger the window, the
more light gets through
and the room is brighter.

31. I S O
• Sensitivity to light
• The higher the ISO number
the quicker the sensor
reacts to light.
• How much light is available?
Is it night or are you inside?

reacts to light.

In the “old days” this
was film speed.

Depends on:
Lighting, Lens, Subject, Artistic Choice

41. E L E M E N T S
O F E X P O S U R E3• Shutter Speed
• Controls the duration of how much
light is allowed to reach the sensor
• Aperture
• Controls the amount of light going
into the camera
• ISO
• Controls the sensitivity of your
camera’s sensor to light
By changing 1 setting, the
others will be affected

42. S U N TA N N I N G
• Time laying out = Shutter Speed
• Longer = Tan
• Too long = Over Exposed
• Sunscreen = Aperture
• Blocks the sun at different rates
(depending on SPF)
• Your skin type = ISO
• some people are more sensitive
than others
