Some Facts
Light is the only and the main source of COLOURs in Digital Photography. In fact, for everything we see around the world. No light No colours. When its brightness rises gradually from black to gray and then white, on a certain point colours comes out and can be visualized by our eyes and by the camera. When it starts glowing, it starts with the Red and Amber colours, changes to Yellow and White, then Sky-Blue and finally to Blue. In its different stages we see the same objects in different colours and tones.
The whiteness of the available Light matters most in Digital Photography for natural colors. With Digital Camera, we actually expose a very sensitive and mass group of micro size electronic pixels, an electronic imaging sensor in place of a colour film.
Unfortunately, getting 100% pure white light all the time, from any of the light source is impossible, let it be daylight or other electrical lights. It also varies according to the situations, environments and time. But the good thing is this that there is a system in all the digital cameras to set a reference value for whiteness of the available Light. The same value as of the light. The question here is, can whiteness of the light be measured ? Yes, it can be measured and measured accurately in degree Kelvin as Correlated Color Temperature.
White Balancing
All the imaging sensors require to set a standard white reference value for the whiteness of available Light to reproduce an image with its original colours. It's like fixing an invisible color filter upon the sensor that corrects impurities mixed in the white light. This procedure is known as White Balancing.
With the accurate WHITE BALANCE settings, a digital camera captures an image and process it in its true and natural colours by eliminating unnecessary colour casts. Again the question here is, can it be measured by incident way because the in-built meter of the camera reads reflected light and may miscalculate in many circumstances and when there is no white object in the scene ?
Kelvino WB master is a light meter which measures Correlated Color Temperature (whiteness) of various kinds of ambient lights used in Photography, such as LED lights, CFL lights, Halogen, Tungsten/Bulbs, or Daylight, etc. It eliminates the need of a Gray Card. It shows readings in Kelvin, which is a unit of color temperature and is directly applicable to set as the reference value for whiteness while setting White Balance in the menu.
Simultaneously, not only this, Kelvino WB master also measures and shows the correction value for Green and Magenta tints in points, to shift the WB graph upwards or downwards on tint-scale.
