A profession of botanical illustrator began to emerge in the eighteenth century with advances in the printing processes. Botanical Illustrations became accurate in color and detail. Amateur botanists, gardeners, and natural historians provided a market for botanical publications. The photographic process has not made botanical illustrations obsolete since illustrators were able to combine accuracy, an idealized image from several specimens, and the inclusion of the face and reverse of the features such as leaves with details given at a magnified scale.

The lantern slides first produced for the 17th century's “magic lantern” devices. The magic lantern, also known by its Latin name Lanterna Magica, an image projector that used pictures on transparent plates (usually made of glass), one or more lenses, and a light source, used for entertainment. The earliest slides for magic lanterns consisted of hand-painted images on glass, made to amuse their audiences. After the invention of photography, lantern slides began to be produced photographically as black-and-white positive images, created with the wet collodion or a dry gelatine process. Photographic slides were made from a base piece of glass, with the emulsion (photo) on it, then a matte over that, and then a top piece of a cover glass. Sometimes, colors have been added by hand, tinting the images. Lantern slides created a new way to view photography: the projection of the magic lantern allowed for a large audience. Photographic lantern slides reached the peak of their popularity during the first third of the 20th century impacting the development of animation as well as visual-based education.

This large AI-assisted collection comprises about 60,000 images of botanical drawings and illustrations. It spans from the 14th to 19th century. As of today, we estimate the total number of botanical illustrations in our archive as 200,000 and growing. The "golden age" of botanical illustration is generally considered to be the 18th and 19th centuries, a time when there was a great deal of interest in botany and a proliferation of botanical illustrations being produced. During this period, many of the great botanical illustrators of the time, such as Maria Sybilla Merian, Pierre-Joseph Redouté, and John James Audubon, were active and produced some of the most iconic and influential botanical illustrations of all time. In addition to being used for scientific purposes, botanical illustrations were also highly prized for their beauty and were often used to decorate homes and other public spaces. Many of the most famous botanical illustrations from this period are still admired and collected today for their beauty and historical significance. All large Picryl collections were made possible with the development of neural image recognition. We made our best to reduce false-positive image recognition to under 5%.

Frances Benjamin Johnston (1864-1952) was an American photographer who is best known for her pioneering work in the field of architectural and landscape photography. She was born in Grafton, West Virginia, and after studying art and photography in Paris, she returned to the United States and established herself as a successful photographer. Johnston's work focused primarily on architecture, and she photographed many of the most significant buildings and structures of her time. She also photographed landscapes, gardens, and people, and her work often appeared in magazines such as House Beautiful, Ladies' Home Journal, and Country Life. One of Johnston's most notable projects was her documentation of historic architecture in the American South. In 1933, she was commissioned by the Carnegie Corporation to photograph historic homes and buildings in Virginia, Maryland, and North Carolina. This work resulted in a series of photographs that are now housed in the Library of Congress. Throughout her career, Johnston was also an advocate for women in photography, and she worked to promote the work of other women photographers. She was a founding member of the Women's Professional Photographers' Association and the Photo-Secession, a group of photographers who sought to elevate photography as an art form.
