Refractive caustic product photography

A solid glass sphere and two unlabeled clear glass bottles stand on a sheet of white plaster while a hard beam from behind-right shines through them, throwing bright ribbed caustic bands across the plaster. No letters, words, signs or logos anywhere in the image. A real photograph of a glass still life, captured on a full-frame digital sensor with a 50mm lens at f/5.6, moderate depth of field, fine grain and sharp transparent edge texture. One hard directional beam from the side and rear shines through refractive forms, concentrating into bright caustic bands and pools across the receiving plane, shading into blocked-light shadows tied to the same geometry. Bright crystalline finish with sparkling bands inside clean neutral tone and deep transparent shadow.
