So, you just bought that thousand-dollar digital camera with full manual control to unlock the artist within. You play with the new features, and take some long exposure night shots and are horrified to see a bright spot in the same locaiton on every picture. No, you haven't discovered a new star... it's the infamous hot pixel, and unfortunately, it's a fact of life.
Don't panic, and don't return your new camera to the store. Your CCD is not defective, and understanding what they are will help you cope. Nearly every camera I own has a couple, and the ones that don't eventually will at some point. They really aren't a problem unless it's smack dab in the middle of the photo, and they appear no matter what your ISO rating is.
