Kevin with Food Coloring and Denatured Alcohol you will need to test a piece as it can be a little weird to use the first time. Other than that it is fairly simple to use. As for taking good quality pictures make a box about 2 feet on a side.the sides, top and back are all open. Drape a white sheet over the box leaving the front open. Arrange strong lighting to shine on the box from the sides and top. The sheet will cause the light to spread out and give you an even light for when you take your pictures.
