Kelvins The color of this logo is meant to illustrate the adjustable range of color temperature or white balance in digital photography. Light sources illuminate from cool blue to yellow with some tinting of green to magenta. A common incandescent lightbulb illuminates with a yellowing effect, while a fluorescent light bulb illuminates with a bluish effect. Each of these different light sources, including the sun, a clouded sky, or even a sunset, register in differing levels of white balance/color temperature which can be referred to in units of Kelvin. The proper balance of this light is what makes a photo interesting and pleasing to the eye. Furthermore, the adjustment of the units of Kelvin can turn a photo from a boring grayscale to a sharp and engaging black and white image. Digital RAW photography allows an amazing amount of image adjustments based on the white balance. All professional digital cameras and many consumer cameras do this by using a file format termed collectively as RAW. This RAW file format is often likened to a digital negative. You also might consider the RAW file format an algorithm for recorded light, which can be adjusted to compliment and accentuate the full dynamic range of the exposed light and colors in any composed image. To put it simply, my first name is also a unit of balancing color to get pure white in digital photography. The significance of adjusting these units and light sources is remarkable! I found a fascination with color and wavelengths of the electromagnetic spectrum before photography. It is sure to continue a lifetime. I hope that you will enjoy my efforts to discover this light and the nature of light in Kelvins. :o) Kelvins Temperature of Color
