3. Pop-up Flash. You may get inconsistent results by aiming the camera and the flash directly
towards the subject, especially in situations where the subject is backlit.
4. Mixed Lighting (More than 2 Light Sources). In open spaces with multiple, diffuse light sources;
aim the camera in the general direction of the lights. In spaces with multiple bright lights, it may be
necessary to balance to the dominant light.
Natural Light
1. Sunlight. Aim the camera towards the sun, but only after installing the ExpoCap.
2. Sunrise and Sunset. When shooting the warm light of a sunrise or sunset, aiming the camera
towards the sun will neutralize the warmth. Aiming the camera away from the sun will enhance the
warmth of the light.
3. Open Shade. Stand near the subject, or in similar lighting and aim the camera back towards
camera position.
4. Clouds. Stand near the subject, or in similar lighting and aim camera back towards camera
position.
5. Filtered Light. Aim the camera through the filtering medium towards the light source.
Troubleshooting
Colorcasts
Occasionally you may experience a colorcast that results in unsatisfactory color. Taking a picture
with an improper white balance will yield an undesirable colorcast. Red, Green, Blue, Cyan,
Magenta or Yellow colorcasts may result from improper use of the ExpoCap.
This can usually be corrected simply by balancing to a different light source. First identify what light
is actually illuminating your subject. Aim the camera away from the subject and balance to the
incident light falling on the subject.
Do not balance towards a backlit subject if the background light is a different color than that which is
illuminating the front of your subject. Instead, balance towards the light illuminating the front of your
subject.
In general, you will get a bluish colorcast if your white balance was set to a warmer light than
actually illuminated the subject at the time of image capture. Conversely, you will get a red or yellow
colorcast if your white balance was set to a cooler light than that which illuminated your subject.
