How to use the Metered Manual Flash Exposures on the EOS 1Ds

Solution

With manual flash exposures, you can set the correct flash exposure by referring to the flash exposure level indicator in the viewfinder. This is useful for close-up flash photography.

You will need a standard 18% gray card and an E-TTL autoflash Speedlite (such as the MR- 14EX) capable of manual flash exposures.

Set the camera and Speedlite settings.
  • Set the shooting mode to <M> or <Av> and select the center AF point.
  • Set the Speedlite for manual flash exposures.

Focus the subject.

  • Focus manually.

Position the gray card.

  • Place the gray card at the same distance as the subject.
  • The gray card should be at a distance where the entire spot metering circle can cover the gray card.

Aim the camera so that the entire spot metering circle covers the gray card, then press the <FEL> button (which remains in effect for 16 sec.).

  • The Speedlite will fire a preflash and the required flash output is retained in memory.
  • In the viewfinder, the exposure level indicator will indicate the currently-set flash exposure level relative to the standard exposure index.

Set the correct flash exposure level.

  • Adjust the Speedlite's manual flash output and the camera aperture so that the flash exposure level indicator is aligned with the standard exposure index.

Compose and take the picture.
