This evanescent trace of a biological specimen, among the rarest of
photographs, was made by William Henry Fox Talbot just months after he
first presented his invention, photography—or “photogenic drawing,” as
he called it—to the public. Talbot’s earliest images were made without a
camera; here a piece of slightly translucent seaweed was laid directly
onto a sheet of photosensitized paper, blocking the rays of the sun from
the portions it covered and leaving a light impression of its form. [Quoted from source]
