Here is a great write up by Joel Ordesky (formerly a SONY F65 product manager). He covers how digital information is captured and how a pixel can be affected and corrected. Many people have heard of a “Dead” pixel in the digital camera industry. But I bet that the term “Lit” pixel is far less understood. Joel’s article sheds some light on where they come from and how to repair them.
