Photographer’s Formulary Classical Gum Bichromate Kit cambo Vivitar 2x Macro Focusing TeleconverterGum Bichromate is a simple imaging process that does not use silver, relying instead on a mixture of gum arabic, dichromate, and pigment; the images produced have lower sharpness than silver printing, with a very distinctive texture. Recommended for contact printing. This kit contains enough chemistry to coat approximately 35 8x10 sheets (sold separately.)
