Hi guys, I'm Justin Z. I am a Los Angeles Independent Filmmaker and a Freelance Video Editor. I've been getting some basic questions about film making including this one which is, "What causes dead pixels on a camera?" Well, when you see a dead pixel it usually shows up as this little black or white dot. A white dot is usually a dead pixel that can be fixed, a black dot is one that cannot be fixed, at least not normally through digital means. A dead pixel can be created through all kinds of things. The main one is when you use your camera a lot. It's just pretty much inevitable. It's a bunch of tiny little blocks with three colors and when you use it enough, it, it just happens. Another thing that can happen is if it gets, the camera gets thrown around, dropped, abused, things like that. Also, if dirt or sand or dust gets into the camera or into the lens, that can happen as well. If you feel you might have a dead pixel in your camera, then, double check your lens, it might just be a spec of dust. It might be a spec of dust inside the lens, you want to get it cleaned out. It might be a spec of dust inside the body of the camera, so,you get that cleaned out. Or, it could be a dead pixel. The best way to avoid this is to treat your camera like a baby; only keep the lenses exposed when you're using it, otherwise keep them completely covered. Always keep a strap around you while you're using the camera, always keep the camera in your hands; don't trust other people that don't know how to use it, things like that. Otherwise, when it comes to a dead pixel, you want to take it into your local body shop and they'll take care of it from there. It maybe very simple where they calibrate the camera and get it fixed that way, which is very inexpensive, sometimes free. Or, they might have to replace the sensor entirely which is a little more expensive. So, if you have any other questions regarding this or other film making techniques, feel free to ask.
