Hello, I have a Nikon D40 that my wife just bought me as Ive always wanted to get into photography. I obviously did something to the camera before R.T.F.M. because now when I take a photo in the preview screen there is, well, I guess a "white noise" its blinking black and white on parts of the photo that are white. This is in all modes, Auto, action, M, A, S, P, etc. Now after messing up the camera I turned to the manual. I shuld of done that first I guess but I was to excited and like most guys just jumped right in. So the manual says in the troubleshooting section it says, "Randomly-spaced bright pixels (noise) appears in photographs. The solution says Lower ISO sensitivity shutter speed is slower than 1s: use noise reduction. Ok, so I go into my menu my ISO is set to automatic and noise reduction is turned on so I am at a loss. I thought maybe my exposure might be off, but the meter is in the middle. Any help is appreciated, hopefully I can get this resolved as I am looking forward to contribute photos in the future. The fight club section looks like fun!
