Taking Photographs-Advanced Photography Avoiding "Grainy" Photographs: Noise Reduction When sensitivity (ISO equivalency) settings above ISO 100 equivalent or shutter speeds slower than 1/ s are used, "noise" in the form of randomly- 15 spaced brightly-colored pixels may appear in photographs, particularly in shadows. The noise reduction menu offers two options for reducing noise: On and Clear Image Mode. Option Description Off All noise reduction options off; camera functions normally. This option, which only takes effect at shutter speeds of 1/ s or slower, is used to reduce noise in 15 On long time-exposures. This setting can be used with the flash and is available at all image sizes. Time required to save images to memory card more than doubles. Clear Image Mode This option is used to minimize noise and improve color gradation in photos SXGA or smaller. Each time the shutter-release button is pressed, the camera makes two exposures with the shutter open, and a third with the shutter closed. The results are compared to reduce noise, and the single photograph that results saved to the memory card. Time required to save images to memory card more than triples. 128
