Partial Metering – Canon

Partial and spot metering modes work similarly. On a Canon, partial metering takes the
exposure from approximately 6.5% of the frame, whereas for spot metering the
brightness is measured using just 2.5% of the framed area.

On Nikon cameras, spot metering takes the exposure from approximately 5% of the
frame. This makes partial metering on a Canon and spot imaging on a Nikon similar.

As they are both similar, consider using partial metering the same as you would for bird
photography. Experiment and see which mode you prefer, Canon Spot or Partial for your
photography.

18% Gray Card

Another type of reflective metering is with an 18% gray card. 18% gray represents the
middle, neutral color. Looking at your histogram black would be on the left edge, neutral
(18% gray) in the middle, and white to the right edge. These are seldom used except for
more advanced professional photographers that want a more accurate metering in
difficult lighting. This is not essential if you are a beginner, but you should know about it.

To use a grey card:
▪ Have the subject hold it close to their
face or place it in the area you will be
focusing on. If your subject is in
shadow the card needs to be in
shadow as well.
▪ Fill the frame of your camera with the
gray card, either by stepping closing or
by zooming in.
▪ Make sure the card is not tilted but flat
up to the lens.
▪ Now, make your adjustments to the
desired aperture, shutter speed, and
ISO until the meter reads at zero.
▪ Remove the gray card and shoot away.
