• Custom White Balance

Setting up Custom White Balance is to rectify original automatic white balance function of digital camera.
By using Custom White Balance Adjustment, users can get more precise color distribution.
Furthermore, by using Custom White Balance, a user’s camera can distributes appropriate RGB (Red, Green, Blue) in order to create neutral gray, artificially.
As a result, the camera can display enormous variety of color resources with micro-precise color distribution.

•  Correct Exposure

Setting Custom White Balance with correct exposing is essential. otherwise, correct white balance adjusting can not be expected.
The best way to guarantee the most correct exposure is to set Automatic Exposure Mode such as “P”, “S”, “A” modes or to set “M” mode with precise exposure meter.

• How to set Custom White Balance

Place Zero WB Filter in front of your camera lens. In order to get the best result, place as close as possible. Set the exposure mode as “AE” Mode, and shoot after adjusting focus-point manually. After that, select or save this exposure or captured image for the custom white balance. You must set different custom white balance for different light.

• Insufficient Color Saturation

Zero WB Filter adjusts color white balance sensor in order to get correct color balance.
There is no camera which can perfectly adjust white balance without sufficient RGB of the subject.
Most of digital cameras can correctly adjust white balance with 2800k~9500k of illuminant.
When the illuminant is out (under or over) of the range (2800k~9500k), the camera may
fail to  adjust correct white balance or an “Error” message can appear on the display.

• Use with other filters

Zero WB filter is available to get installed on the other filters such as Skylight Filter, Polarizing Filter.
However, the light which is distributed by such filters is individual, and the camera maybe failed to adjust correct color
balance.

• Use with Digital Video Camera

Zero WB Filter is also an excellent white balance tool with Digital Video Camera.
Put WB Filter on the lens and point the camera toward the background or illuminant.
Shoot with the “custom white balance” button of the video camera.

• Digital Exposure Meter FunctionZero WB Filter can be used as a simple digital incident exposure meter by the instruction followed:1) Under the same illuminating condition, put the Zero WB Filter on the camera lens being set as Manual Mode.
  2) Standing on the same position of subject, point the camera lens toward the illuminant.
  3) Turn on the camera, adjust the aperture & shutter speed in order to get a desirable exposure condition.
  4) Remove Zero WB Filter from the lens and start your photographing  standing on the shooting position.
