Manipulating Focus and Color
IN THIS CHAPTER
Controlling the camera’s focusing performance
Sorting through autofocusing options
Understanding focal length and depth of field
Exploring white balance and Picture Styles
To many people, the word focus has just one interpretation when applied to a photograph: Either the subject is in focus, or it’s blurry. But an artful photographer knows that there’s more to focus than simply getting a sharp image of a subject. You also need to consider depth of field, which is the distance over which focus appears acceptably sharp. This chapter explains all the ways to control depth of field and also discusses how to use your camera's advanced autofocus options.
In addition, this chapter dives into the topic of color, explaining White Balance, a feature that compensates for the varying color casts created by different light sources, and Picture Styles, which affect image sharpness and contrast as well as color.
Note: Focusing information in this chapter relates to viewfinder photography only. Both automatic and manual focusing work differently in Live View and Movie modes, so see Chapter 4 for focusing help when using those features.
