ExpoCap Instructions
Custom White Balance Aid
Before using your new ExpoCap Custom White Balance Aid, please refer to your camera manual for
specific instructions on how to set a custom white balance.
Getting Started
IMPORTANT: Do not point your camera directly at the sun without the ExpoCap installed.
Direct sunlight may damage or destroy your camera’s image sensor.
Custom White Balance (WB)
Setting a custom white balance on your digital camera will help you get better color under many
difficult lighting conditions. Using the ExpoCap to help set the custom white balance is simply the
quickest and easiest way to help your camera capture richer, more beautiful colors.
Installation
Squeeze the two buttons on the exterior of the filter ring and insert the ExpoCap into the threaded
recess in front of your camera lens. To remove the ExpoCap, simply reverse this action.
Stacking ExpoCap With Other Filters
The ExpoCap can be installed and used as intended over other camera filters, such as Skylight or
Polarizing filters. Note that any color characteristics introduced by filters stacked with the ExpoCap
during the custom white balance procedure will be neutralized in the process. If color correction
from a filter is desired, then the custom white balance must be taken without the desired filter in
place.
Proper Exposure
It is essential to obtain a proper exposure while setting a custom WB. Failure to do so may result in
the inability to set a correct balance. The most convenient way to obtain a proper exposure through
the ExpoCap is to use an automatic exposure (AE) setting such as the “P” “S” or “A” modes.
How to Set a Custom WB Using ExpoCap
Install the ExpoCap on the end of the lens. Set your camera to an AE mode, set your focus to
manual (your camera may not respond in auto focus with the disc installed), then press the shutter
release button. Select or save this setting or the resulting image as the reference for your custom
white balance. You must set a different custom white balance for each change in lighting.
Where to Aim the Camera
The best results are obtained by standing near, or in similar lighting as your subject and pointing the
camera back towards the position from which you will take the picture. In other words, the same
color of light falling on your subject must also strike the front surface of the ExpoDisc. See the
following examples for tips in some common lighting conditions.
Artificial Light
1. Single Light Source. Aim the camera towards the light source.
2. Dual Light Source. Aim the camera midway between the lights.
