Metered Manual Flash Exposures
When using an EOS-1D series camera, the flash exposure level can be
manually set before shooting. This is effective when you are close to the
subject. Use a 18% gray reflector (commercially available) and shoot as
follows.
1
Configure the camera and Speedlite settings.
Set the camera's shooting mode to <a> or <f>.

Set the Speedlite flash mode to <a>.

2
Focus on the subject.
Focus manually.

3
Set up an 18% gray reflector.
Place the gray reflector at the subject's position.

Aim the camera so that the entire spot metering circle within the

viewfinder center is over the gray reflector.
4
Press the <B>, <P>, or <7> button.
 The Speedlite will fire a preflash and the required flash output for
the correct flash exposure is retained in memory.
 On the right side of the viewfinder, the exposure level indicator
will show the flash exposure level against the standard exposure.
5
Set the flash exposure level.
Adjust the Speedlite's manual flash output and the

aperture so that the flash exposure level aligns with
the standard exposure index.
6
Take the picture.
Remove the gray reflector and take the picture.

Metered manual flash is available only with EOS-1D series cameras.
