CHAPTER NINE
Reducing Noise, Correcting Chromatic
Aberrations, and Controlling Vignetting
With varying degrees, all digital cameras produce images
with electronic noise, chromatic aberrations, and vignetting.
Electronic noise shows up as extraneous pixels sprinkled
throughout an image. Chromatic aberrations appear in
transitional tonal areas as colored halos, color banding, or
purple fringing (especially around backlit edges). Vignetting—
darkening around image edges—occurs with a filter-lens-
sensor mismatch. In this chapter, I’ll cover how you can reduce
the effects of these imperfections in your RAW files using either
Adobe Camera Raw or Photoshop.
