Hey, I have a Nikon CoolPix 775 digital camera...is there a way I can take pictures of a tv screen besides just pointing the camera at it and taking a pic? It came with a cable which lets me hook the camera up to the tv, but then the tv only shows what the camera sees, I want it the other way...I want the camera to show what the tv has on it, so that I can take pictures of it....thanks
