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.
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
