Noise Reduction G button ➜ C shooting menu Select On to reduce noise (bright spots, randomly-spaced bright pixels, or fog). Noise reduction takes effect at all ISO sensitivities, but is most noticeable at higher values. The time required for processing at shutter speeds slower than about 1 s roughly doubles; during processing, "l m" will flash in the viewfinder and photographs cannot be taken. Noise reduction will not be performed if the camera is turned off before processing is complete. If Off is selected, noise reduction will only be performed as required; the amount of noise reduction is less than that performed when On is selected. Vignette Control G button ➜ C shooting menu "Vignetting" is a drop in brightness at the edges of a photograph. Vignette control reduces vignetting for type E and G lenses (0 267). Its effects vary from lens to lens and are most noticeable at maximum aperture. Choose from High, Normal, Low, and Off. A Vignette Control Depending on the scene, shooting conditions, and type of lens, JPEG images may exhibit noise (fog) or variations in peripheral brightness, while preset Picture Controls that have been modified from default settings may not produce the desired effect. Take test shots and view the results in the monitor. Vignette control does not apply to movies (0 127) or to pictures taken with lenses that support FX format.
