Description
The velvety texture of rose petals is produced by conical epidermal cells — cells whose apex extends above the petal surface, creating a microscale regular array of cones that diffuses reflected light rather than specularly reflecting it, producing the characteristic soft texture and the deep colour saturation of the petal surface. This photograph, made with a specialized objectives-and-bellows macro configuration at 8:1 reproduction, resolves the individual conical cells of the petal surface as three-dimensional objects casting tiny shadows on the surrounding cell surfaces — the entire field of view occupied by the regular array of epidermal cones that, at this scale, resembles a field of conical towers viewed from above. The deep crimson colour of the petal is reproduced with full pigment accuracy.
