Flash - Canon Speedlite 470EX-AI Instruction Manual

Metered Manual Flash Exposure
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 an 18% gray reflector (commercially available) and shoot
as follows.
1
Configure the camera and Speedlite settings.
Set the camera shooting mode to <a> or <f>.
Set the Speedlite's 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 exposure is available only with EOS-1D series
cameras.
