Metered Manual Flash Exposures
When using an EOS-1D series camera, the flash exposure level can be
manually set before shooting. This is convenient for shooting at a short
distance from the subject. Use a 18% gray reflector (commercially
available) and shoot as follows.
1
Configure the camera and MR-14EX II settings.
Set the camera's shooting mode to <a> or <f>.
Set the MR-14EX II'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 at the
viewfinder center is over the gray reflector.
4
Press the <B>, <P>, or <7> button.
The MR-14EX II 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 MR-14EX II's manual flash level 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.
