title: Colored filters for microphotography: a costless 'do-it-yourself' solution.
abstract: Black and white microphotography makes use of several colored filters for an increased contrast. These filters are sometimes expensive and do not correspond exactly to the stain to be masked on the negative. Our specific colored filters contain a sufficient and adjusted amount of the dye used in the staining technic in an Agar medium.
