Weekly Vocabulary

1. A wide-angle lens is a type of camera lens that has a shorter focal length and a wider field of view compared to a standard lens. This makes it useful for capturing expansive landscapes, large groups of people, and interiors.

1. Reciprocity in photography refers to the relationship between the amount of light entering a camera and the exposure time needed to produce a correct exposure. With traditional film cameras, this relationship was straightforward, but with digital cameras and some types of film, the relationship can become more complex and may require adjustments to account for reciprocity failure.

1. Open shutter photography is a technique where the camera's shutter is left open for an extended period of time, typically several minutes or more, to allow for the accumulation of light over time. This can produce unique and often ethereal images, particularly when used in low-light or nighttime scenes.

1. Long exposure photography is a type of photography that involves using a slow shutter speed to capture motion and light over an extended period of time. This can produce unique and dramatic images, particularly when used with moving water, clouds, or other elements that create dynamic patterns in the image.

1. Light painting photography is a technique where the photographer uses a light source, such as a flashlight, to illuminate a scene or subject during a long exposure. By moving the light source in creative ways, the photographer can produce interesting and often surreal images. Light painting can be used in a variety of settings, including indoors and outdoors, and is often combined with other types of photography, such as night photography or long exposure photography.
