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.

    
                     The positive side with light-guiding posts outwards is good for indoor photograph; 
                         The reversed side is good for indoor portrait or landscape photo outdoor.



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.

View at the time of WB-Lock when the light is guided and mixed to the
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.


      

* 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:   
                

* Camera AWB has a tendency to capture the cloudy outdoor photo in a wrong cool tone as if it was in noon time of a sunny day. Use the PIPE in reversed direction to do WB-Lock will help to capture the real color as shown in the following comparison photos:

             

  The above are just three 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.
