Photoshop CS2 Raw: Reducing Noise, Correcting Chromatic Aberrations & Controlling Vignetting

Overview 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. This paper covers how one can reduce the effects of these imperfections in the RAW files.
