Throughout the 1930s Dr. Dain L. Tasker, a radiologist, used fine-focus X-ray tubes to produce floral studies on X-ray film. Published in "U. S. Camera" and "Popular Photography" Tasker''s work was hailed for its beauty. "Flowers are the expression of the love life of plants," he once wrote. Sublime in their minimalist sensibility, these images of flowers are ethereal, ghost-like representations. The inherent transparency of Tasker's chosen medium also reveals the strength of the plant's structure, lending the image a sort of eroticism and dynamic modernism.
