Photo on Granite

Things have been really busy. SWMBO is working on the taxes and looking at new products for a good customer of ours. I may be the guy that runs the laser and draws the art work but Metal Markers could never survive without all the work my wonderful wife does. I know I try her patience on a daily basis but I really don't mean to!!!!
Well, back to the subject. A friend of mine requested I "rough up" a piece of granite with the laser to be able to attach a photo to it. I suggested we just put the photo on the granite. We got the photo and it was pretty rough. It was taken in 1861 so what can one expect? I worked on cleaning up the photo and a friend of mine from the UK offered to work on it also. He must have spent several hours on it and ran it through an engraving program called "Photograv". I ran the photo on the laser on a piece of absolute black granite but I wasn't 100% happy with the results. My buddy in the UK sent me several pictures he'd worked on and I picked out one I thought looked good. I tried it using 100% speed 100% power and 300dpi and was pleased with how the engraving turned out. I believe folks think that because we use a computer and a laser that any one can do this. I have no idea how many hours went into this project and we scrapped 3 pieces of 12 x 12 granite. Getting rich? I don't think so Tim.
