Hi everyone, The SD card has now arrived for my brand new D80. It's alive. I took a couple of test shots out of the bedroom window, and all looked fine. I remember seeing on here some months agao something about dead pixels, so I thought I would take a look. I tried taking a long exposure with the lense cap on (bulb setting for 30 seconds). The camera wouldn't focus, so I removerd the lens and replaced with the lense blanking plate no lens attached). 1st pic looked fine, but relaised it was a JPG, ISO 100. Turned up the ISO to 1600, turned off high ISO noise and took a Large Fine JPG +RAW shot. There was an arc of bright (red and green) dots on the JPG, and the RAW, on maximum zoom in iPhoto looked like a koleidescope on a black background, with the JPG dots very prominent. Have I done something wrong, or is this a particulary bad sensor. I am really new to photography, :Shy: and need some reassurance that I haven't bought a dud! Can anyone help?
