ABSTRACT

Chapter 7 discussed neutral balance in the workflow, and this chapter examines why we need to balance for the light’s spectral bias, where in the process we can apply balancing, and how balancing is accomplished. These corrections can be made within the capture workflow, using post-capture software applications, or via output control.

Photography, whether with conventional film or digital imagining, is about capturing light. The term photography is derived from the Greek words for light and writing, thus reflecting the importance of understanding light to make good images. As explained in Chapter 7, a major problem in balancing a picture so that the colors are captured correctly is the way our perceptual system works. The human perceptual system holds constant as much of the learned world as possible. This constancy has a great effect on our perception of color, as well as our ability to neutralize light. To
