My Camera's on it's holidays

My Camera's been having a few issues lately so is curently in Jo'burg visiting the Canon repair shop.

For those of you interested in digital photography here's some info for you I didn't know about digital cameras. Cameras can develop dead pixels on the CCD which show up as white pixels with lots of interpolation around them. The white dot where the CCD is getting erroneoud image data and the interpolation where the camera is trying to smooth the image data as part of normal processing. This as you can imagine is pretty annoying once you know it's there. I've discovered that all cameras have dead pixels on the CCD but in the factory these are cloned from a neighbour so you don't see them. So to get newly dead pixels sorted out they're supposed to be able to do this re-cloning to hide the newly dead ones.. Get this - Olympus cameras do this automatically. Nikon, Canon you've got to send for repair.

So now you know..
