This seems to fit in the "Do No Harm" category, using a natural product that can be easily removed to enhance the lettering on a stone to make it easier to see and photograph. The wife discovered this posted on a "My Family" website. George G. Morgan, noted genealogist and author, recommended using flour or cornstarch when photographing tombstones. George says the flour or cornstarch is a natural material that won't harm the stone. Pat the flour or cornstarch into the stone with your hands (gloves might be a good idea here) or use a very soft brush, maybe a paint brush or George recommended a small make-up brush. When you're finished photographing the stone, make sure you use plenty of water to rinse the flour or cornstarch off the tombstone. This link was provided to show a "before and after" photo of a stone using that method: http://bronzestar.tripod.com/cob9thky/id4.html Has anyone else seen this method used? Any opinions on it? Ernie
