I started advanced photography at sait last Thursday, Last class we went over bit depth, colour space, histograms, light sensors and white balance!
I tried doing a series of shots to help me understand the color changes of white balance, I took the same picture 6 different times not changing anything but the white balance..
White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. Proper camera white balance has to take into account the "color temperature" of a light source, which refers to the relative warmth or coolness of white light. Our eyes are very good at judging what is white under different light sources, however digital cameras often have great difficulty with auto white balance (AWB). An incorrect WB can create unsightly blue, orange, or even green color casts, which are unrealistic and particularly damaging to portraits. Performing WB in traditional film photography requires attaching a different cast-removing filter for each lighting condition, whereas with digital this is no longer required. Understanding digital white balance can help avoid color casts created by your camera's AWB, thereby improving your photos under a wider range of lighting conditions.
