| Berenice Abbott Light Rays through Prism [Retrospective Portfolio (Parasol Press) 1982] 1958 (ca) Gelatin silver print 16 x 24 Clark House Gallery LL/4892 Hank O' Neal Berenice Abbott:American Photographer (1982) wrote:
Multiple beams of light from a source change direction when they go into a glass plate and when they emerge. Some waves are reflected inside the glass and then escape. The prism photograph was done very carefully. The prism was filled with water and not one drop of air was inside. The box that held the light source was specially designed and purposely looks as it does to make for a better composition.
