Holography Film Developer JD-2 is a developer for both transmission and reflection holograms. It is relatively safe, even for the home hobbyist, and is recommended by Dr. Jeong of the Lake Forest College holography workshops. When making white light reflection holograms with a He-Ne laser, this process allows you to control the color of the image from red to blue depending upon the exposure. Underexposure yields red; over-exposure yields blue. Correct exposure yields a gold color.
