Daguerreotypes are detailed, one-of-a-kind photographs made on silver-coated copper plates. This photograph is commonly known as *Still Life with Plaster Casts* (or *Still Life in the Studio*) and was made by Louis-Jacques-Mandé Daguerre. Daguerre is significant because he developed the daguerreotype process, one of the first practical methods of photography. He publicly introduced the process in 1839.

The aperture is the adjustable opening that controls how much light enters the camera. The lens focuses light to form an image on the camera’s sensor or film. The shutter opens and closes to control how long light reaches the sensor or film.

Digital photography is a process in which there is no film yet the image is exposed the same way the digital camera does. With digital photography, the charge-coupling device is exposing light to thousands of little dots that record the light into pixels. The pixels can be recreated or reproduced onto the computer and then printed. Digital photography has opened up the doors for photographers, allowing artists to manipulate images and create images or scenes that may never have existed.

This photograph is a botanical cyanotype, often identified as a cyanotype of plants, by Anna Atkins. To create it, Atkins placed plant specimens directly onto paper coated with light-sensitive chemicals and exposed the paper to sunlight. The areas covered by the plants remained pale while the exposed areas turned blue, producing a photogram. The cyanotype process is commonly used to make blueprints.

Aperture: The opening in a photographic lens that admits light. Lens: The glass over the opening that focuses the incoming image. Shutter: A device in a camera that opens to allow light through the lens and exposes the film when a photograph is taken.
