When white balance is incorrect, colors will appear muted, washed out or distorted.
White balance is based on the concept of “color temperature,” the relative warmth or coolness of the light conditions under which you are shooting. Color temperature is measured in degrees Kelvin (°K) and varies widely depending on the context of your shot.

Understanding color temperature can be a bit confusing at first, because blue, what would typically be called the “coolest” color, actually has the highest color temperature, 8000 °K and up. Orange, red and yellow light, the “warm” colors, have the lowest color temperatures, around 1500 to 3200 °K.

Different light sources have different color temperatures and cast according colors on the subjects of your photographs. White rose petals will have an orangey cast under the cool light of a tungsten light bulb and a blue cast under the warm light of an overcast sky.
A properly “white balanced” photograph will have clean, clear whites (and other colors) that perfectly match the subject.

AWB vs. CWB with baLens Neutral

With your camera set to custom white balance and the baLens Lens Cap installed, you will be able to achieve an accurate color temperature reading in seconds. The conventional method of setting a custom white balance involves taking a reading of reflected light from a gray card or white piece of paper. Not only is this cumbersome, but it may still be inaccurate if the card or paper is held at the wrong angle. The baLens Lens Cap allows you to take a reference reading directly from the light source, avoiding the guesswork. Photos will be recorded with the colors as seen while shooting so there will be no guesswork in post processing.
