                                        Product introduction & how-to-use video

RAYNAULD™ DCC and DWB patented filter use an optical filter unit to avoid the miscalculations of the automatic white balance (Camera AWB) often makes and in this way avoid color deviation. Thanks to the main filter which lays in the small tube-like part of the black body structure, the light-guiding body, concealed in the filter lens cup and the light-guiding posts in the main filter, you can capture the most exact color temperature and use it to set the color system of the camera phone. In this way, you can achieve the most true-to-the-original colors of the scene.

You don’t need the gray card to shoot RAW and edit the photo with special software later; you can make almost perfect color photos directly on your smartphone right there and enjoy the colorful moments of life. It makes the modern art creation processes time-saving and easy; to the maximum extent keeps the colors of the photo close to the original.

Main function: Using the patented optical filter to turn your camera phone into a professional color temperature meter to capture the real color photo/video.  The DWB/DCC filter prevents the miscalculations of the automatic white balance (AWB) which lead to color deviation.

Usage Occasion: Indoors. When the camera phone has color cast problems for photographing or video recording.

Functional Characteristics:

1 Collecting the scene light in directivity

  The camera lens of the phones usually has a design which allows it to collect light with an 180° field of view that leads to read the wrong color temperature value of the pictured scene. The patented design of RAYNAULD DWS Filter uses an optical filter which has a light-guiding and cup-shaped structure concealed inside a barrel body. By this way, the filter can collect the light partially and selectively to avoid non-selective light absorption from all directions.

  This is the secret behind the almost perfectly colored photo from RAYNAULD™ DWB/DCC
  Filter.  See details.

2 Professional entity optical filter

  DWB Filter uses a professional entity optical filter with light-guiding lens cup to take the rays of light captured in the restricted field of view and turns them into a compensation value for the camera’s grey system. It accurately indicates what is the actual white color average value of the scene in front of the camera. Thus, it can avoid the possibilities of miscalculations of the camera’s automatic white balance (AWB) totally.
3 Homogenizes the rays of light

  The light-guiding wall of the filter cup and the light-guiding posts on the filter’s surface make the collected rays of light homogenized in the center of the filter. In this way, it provides the color temperature meter with the most accurate the color temperature average value.

center of Filter through the filter, encircled wall and posts.

4  Conform to the color temperature average value of the scene

  The DWS filter directs the light and collects it partially. Thanks to the unique light-guiding filter lens cup, the light-guiding posts and other physical methods, the filter provides the color temperature system of the camera with an average color temperature value which is the most well-adjusted to the scene you are shooting. In this way, your pictures and videos can have true-to-the-original colors.

5 Camera phone grey color system

  The camera phone grey color system is the same as the DSLR camera. The aim of the DWB optical light filter is to carry out an accurate compensating correction of the SLR camera grey system. Using the same principle of physical optics, the filter can correct the colors of photos and videos made by camera phones.

6  Real colors

  Each picture and video frame made with a digital camera uses a single color temperature value to define the white and all other colors in the scene. Only if the scene has an accurate color temperature value, it is possible to make real color pictures correctly! Make pictures authentic to the human eye vision and avoid the miscalculations of the camera’s automatic white balance (AWB).

  You don’t need gray card to shoot RAW and edit the photo with special software later; you can make almost perfect colored photos directly on your smart phone and right there enjoy the colorful moments of life. It makes the modern art creation processes time-saving and easy; keeps the the colors of the photo close to the original at the maximum extent. Create original work with perfect colors in one shot.

* When the object is too close to the camera lens, the automatic white balance (AWB) system of the camera cannot find a referent for the white color or other colors close to white (for example: a bright spot). Therefore, it can easily make a miscalculation in the white balance compensation value, as shown in the following example with the yellowish jeans:

* In the next photo scene, the strong light source on the ceiling shines directly into the camera lens and in this way it gives the photosensitive parts incorrect color temperature.
If the average color temperature does not correspond to the actual colors of the scene, the automatic white balance (AWB) of the camera naturally produces photos in wrong colors, as shown in the following example:

  The above are only two of the numerous examples for color deviation from Camera AWB. There are too many circumstances with photo color deviation enumerate. Here are some more examples.

Not all Android smartphones which have the white balance lock function that can use RAYNAULD Directivity White Balance Filter or Color Calibration Filter. Please check the APP’s instructions.

Instructions:  Cover the camera lens with the filter only when doing the White
                        Balance Locking. After the White Balance Locking is completed,
                        remove the filter and start to shoot.

How to use:

● When using the filter, either on its front or its reverse side, you should always press
   the filter tightly against the phone surface.

● For the best results, place the light-collecting area of the filter in the center of the
   camera phone’s display.

●  Photo style: Please select FAITHFUL, NATURAL or TRUE mode only.

● If the AWB of the camera and the filter give the same results on some occasions,
  it means that the phone’s AWB is working perfectly fine for that occasion. This
  doesn’t mean that the filter doesn’t play any role – IT IS PERFORMING PERFECTLY.

● The exposure is an important element composing the colors. In order to achieve
   the most true-to-the-original colors, please make the necessary adjustments
   on exposure according to the scene (if it’s too light or too dark exposure) before
   or after taking the photos.

● If there is a considerable change in the scene or the light source, use the filter
   again to lock the white balance for the new scene.

● How to prove the effect of the Color Calibrating Filter? Take a photo using
   RAYNAULD DWB or DCC filter and compare it with the colors of the actual scene
   immediately. You have a proof!

● If while using the DWB filter or the DCC filter there is still no color correction
   effect, take two or three steps back, use the DWB filter or the DCC filter again
   to lock the white balance, then approach the object and take the photo.

● RAYNAULD™ DWB filter and DCC filter can acquire the most accurate white
   balance average value and can also make photos and videos of true colors.
   However, the displaying of the colors photo is limited by the camera’s color
   reproduction capacity.

● After you cover the camera lens with the filter, wait for one or two seconds
   before press the key for locking the white balance in order to acquired is the
   most accurate color temperature value.
