Hi. I own an Olympus C-740 Ultrazoom digicam which performs beautifully except for one thing: it always pixellates and dots neutral grey areas. If the subject happens to be any color from light brown to grey to dark green, black dots and pixellation rear their ugly heads. Could this have to do with the white balance? Thanks

Re:
No, it isn't to do with white balance. Instead it is due to a combination of noise swamping (or at least modifying significantly) the exposure measured by the pixel, and the interpolation algorithm in the sensor processing chips that "guesses" the colour of a pixel based on the readings from nearby pixels. These algorithms are better at rendering certain kinds of image elements than others. Large areas of darkish colour often fool the algorithms into attempting to produce detail that doesn't exist.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.
Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo management program such as Picasa ( http://picasa.google.com ).
Could be whats known as dead pixels, this is tested be showing up a black or white screen. Microsoft paint or word will do. If an area always has dots then dead pixel. However if it doesn't constantly remain a dot then, some-thing else. Dead pixels come about due to age.
A technician will be able to diagnose your problem by performing white screen test.
purchase another card (smaller memory and cheaper...as a test). install it. if it works, then read file folder names under windows and then copy these folders over to the 1GB card.
Pixel Mapping is a feature of the camera to check and adjust the CCD and image processing functions. Locate Pixel Mapping in the camera's Menu and select OK to activate it. Once Pixel Mapping is completed the Menu displays. The bright dot should no longer appear in your downloaded images.
