The Magic of Light

Electronic flash may have a slightly blue colorcast. To reduce the blue, set the Flash WB. Some flash units have a yellow-filtered flash tube to eliminate the colorcast. The Flash WB option is very similar to the Cloudy WB. High Dynamic Range imaging (HDR), works perfectly well for lowering the contrast of motionless subjects. Graduated neutral density filters are various densities of gray on one-half of the filter and clear on the other half. These filters are used to lower the contrast in landscapes. Polarizers are quite useful when photographing ponds, lakes, and oceans. Use a polarizing filter to remove this glare. To regularly use color temperature option you need an expensive color temperature meter. Perhaps that is the reason many cameras do not offer it. If you have the Color Temperature WB option and desire red sunrises or sunsets, follow this procedure: Set the Color Temperature WB.
