Line describes a dominant path of movement in an image. Lines can vary in direction and length. For example, they can be horizontal or vertical, straight or curved. By creating paths through the image, lines help communicate information and influence our interaction with the image.
Photographic ephemera typically refers to paper-based objects that incorporate photographic images (postcards, posters, broadsides, pamphlets, etc.). These objects are inexpensive, broadly circulated, and mass-produced to serve various and immediate uses (commercial, commemorative, educational, decorative, promotional, etc.).
Texture is the surface quality that can be seen and felt in an image. Textures can be smooth, granular, and so on. Ask: If you could touch the surface of the photograph how would it feel? When textures repeat, this can form a pattern.
Vantage point is the position from which the photographer takes the photograph. The vantage point can be from a particular angle: straight on, or at a diagonal, for example. It can also be elevated, at a distance, or close in proximity.
Gelatin silver prints is a general term that describes the most common process for making black and white photographs since the 1890s. They are made with papers coated with a layer of gelatin that contains light-sensitive silver salts.
Digital photography describes the art and science of producing and manipulating photographs that are represented as pixels. Digital photographs can be produced in a few different ways, including by digital camera or by scanning. Digital images are also created by non-photographic equipment, such as computer tomography scanners and radio telescopes.
