Description

Procedure to select the metering mode of the EOS 1Dx Mark III.

Solution

Metering Mode Selection

Metering Mode Selection

You can select one of four methods to measure the subject brightness.

  1. Press the Flash exp comp/metering mode button (Timer 06sec).

  2. Select the metering mode.

    • Watch the top LCD panel or look through the viewfinder as you turn the Main Dial dial.

  • Evaluative metering Evaluative metering

    General-purpose metering mode suited even for backlit subjects. The camera adjusts the exposure automatically to suit the scene.

  • Partial metering Partial metering

    Effective where there are much brighter lights around the subject due to backlight, etc.

  • Spot metering Spot metering

    Effective when metering a specific part of the subject. The spot metering circle will be displayed in the viewfinder.

  • Center-weighted average metering Center-weighted average

    Metering over the entire area is averaged, with the center of the viewfinder weighted more heavily.

Note

  • By default, the camera will set the exposure as follows.

    With Evaluative metering, holding down the shutter button halfway locks the exposure value (AE lock) after the camera focuses with One-Shot AF. With Partial metering / Spot metering / Center-weighted average metering, the exposure value is set at the moment the picture is taken (without locking the exposure value when the shutter button is pressed halfway).

  • You can link spot metering to all AF points by setting [Custom Functions1: Spot meter. linked to AF pt] to [Linked to active AF point] ().
  • With [Custom Functions2: AE lock meter. mode after focus] (), you can set whether or not to lock the exposure (AE lock) when focus is achieved with One-Shot AF.

Multi-Spot Metering

By specifying multiple areas for spot metering, you can determine an overall exposure level based on the average of your selected areas. Multi-spot metering is available in Program AE, Shutter priority AE, and Aperture priority AE modes.

  1. Set the metering mode to Spot metering (spot metering).

  2. Press the Multi-function button (Timer 16sec).

    • Aim the spot metering circle over each area for exposure comparison, one after another, and press the Multi-function button in each area.

    • Relative exposure levels of each spot metering area are displayed at right in the viewfinder. These levels are averaged to obtain the current exposure level.

    • While referring to the three points on the exposure level indicator, you can set exposure compensation in this state and determine the final exposure level for the desired result.

Note

  • Spot metering with up to eight points is possible.

  • Stored exposure values are cleared in the following cases.

    • When the metering timer elapses after the last spot metering (Timer 16sec)
    • When you press any of these buttons: MODE, Drive mode/AF operation, Flash exp comp/metering mode, ISO, AF point selection, Exposure comp., or White balance selection
  • Multi-spot metering is available even when [Custom Functions1: Spot meter. linked to AF pt] is set to [Linked to active AF point] ().
