This is not something for amateurs. You really have to know what you are doing. For example, when you try the raise the #s with heat, you have only one chance to do it as the cast iron molecules change from their original stamped, stressed state to a de-stressed position. The numbers may only be visible for a very brief amount of time for you to capture them with a camera. And if you dont know how to take a macro photograph properly you may have lost your one and only chance.
