English Instructions

White Balance

1. Cover the Lens. Attach the ExpoDisc to the front of your lens (white side towards

camera). If your ExpoDisc is larger than your lens fi lter size, simply hold the ExpoDisc
fl at over the lens.

2. Manual Camera Focus (If Necessary). Some cameras require the lens to be in

manual focus to capture an exposure through the ExpoDisc. Note: This is not necessary
when using Nikon cameras to set a Preset white balance.

3. Set Exposure. Camera Program or Aperture mode will automatically produce a good

exposure through the ExpoDisc (when shooting in ambient light). If shooting in Manual
mode (or with fl ash), set a proper exposure prior to setting the custom white balance.

4. When Using Flash. You must set your custom white balance using the same shutter

speed that you intend to use when photographing your subject. Your fl ash must fi re
when setting the custom white balance.

5. Aim the Camera (Measure Incident Light). Aim the camera towards the

dominant light source (just like an incident light meter). Note: The light illuminating
your subject must pass through the ExpoDisc, which may require you to stand at your
subject’s position.

6. Set the Custom White Balance. Follow your camera’s custom white balance

procedure to take a white balance reading. Detailed instructions for many camera
models, as well as video camera tutorials are available at www.expodisc.com/support/.

7. Finished. Remove your ExpoDisc and return your camera to autofocus, if necessary.

Take a new custom white balance reading whenever your lighting changes.

White Balance Tips

Measure the Incident Light. Understanding that the ExpoDisc is an incident metering

tool will help you to use it properly in a variety of shooting situations, including in-studio,
outdoor, ambient light, and in certain on-camera fl ash applications.

Ambient Light (Indoor or Outdoor). Aim the ExpoDisc towards the brightest light

source, or area of the sky. It is best to stand in the same light as your subject to set the
custom white balance. Note: Direct sunlight poses no risk to the camera’s optics because
the ExpoDisc diffuses and passes only 18% of the light through to the camera’s sensor.

Off-Camera Flash. Point the camera towards the main light (key light) to set your

custom white balance.

On-Camera Flash (Bounce Flash). Aim the camera and the fl ash towards the bounce

surface (e.g., ceiling) to set your custom white balance.

On-Camera Flash (Direct Flash). We do not recommend setting a custom white

balance with the ExpoDisc when directly lighting subjects with on-camera fl ash. Doing so
may create an undesirable colorcast by incorporating back-lighting or side-lighting.

White Balance Portrait Warming Filters (optional)

Portrait Warming Filters (gels) attach to the front of the ExpoDisc 2.0 to create warmer
images for pleasing skin tones.

ExpoDisc 2.0 includes two levels of custom Warming Filters (gels) which can be inserted
into slots on the face of the ExpoDisc. Under daylight balanced studio lights, the +1 and
+2 custom warming fi lters provide 250˚ and 400˚ Kelvin warming, respectively.

White Balance Portrait Warming Filters (continued)

To use a Portrait Warming Filter, attach the fi lter to the front of
the ExpoDisc (prismatic lens side). The two fi lter tabs should be
placed into small grooves located on the rim of the ExpoDisc.

Note: Your ExpoDisc will not correctly meter 18% incident

exposure with the Portrait Warming Filters attached.

Metering for 18% Incident Exposure (optional)

To meter exposure for evenly lit subjects with minimal highlight and shadow areas:

1. Attach the ExpoDisc to your camera lens.

2. Put your camera in Manual exposure mode.

3. Stand at subject position, then point the camera toward your intended shooting position.

(Note the camera meter as seen through the view fi nder).

4. Adjust aperture, shutter speed, or ISO settings until camera meter indicates a proper exposure.

5. Take one test shot through the ExpoDisc.

6. Check the histogram of the test shot. A correct exposure should yield a gray image with

a centered spike.

7. Remove the ExpoDisc to photograph your subject.

To Expose for Highlights and Shadows

- To expose for highlight detail, increase your exposure 1 f/stop.

- To expose for shadow detail, decrease your exposure 1 f/stop.
