Picture frame in the context of Picture

A ruling pen is a drawing instrument for drawing with ink or with other drawing fluids. Originally used for technical drawings in engineering and cartography together with straight rulers and French curves, it is today used for specific uses, such as picture framing or calligraphy. Drafting compasses are also sometimes provided with ruling nibs.

In filmmaking, video production, animation, and related fields, a frame is one of the many still images which compose the complete moving picture. The term is derived from the historical development of film stock, in which the sequentially recorded single images look like a framed picture when examined individually.

The term may also be used more generally as a noun or verb to refer to the edges of the image as seen in a camera viewfinder or projected on a screen. Thus, the camera operator can be said to keep a car in frame by panning with it as it speeds past.

A framer is someone who builds or creates frames. In construction work, frames may be built from wood or metal and provide support and shape to a structure. In a related sense, framers may create frames for art works, pictures, or mirrors. The term framer is also used for the authors of a formal text such as a constitution.

A cavetto is a concave moulding with a regular curved profile that is part of a circle, widely used in architecture as well as furniture, picture frames, metalwork and other decorative arts. In describing vessels and similar shapes in pottery, metalwork and related fields, "cavetto" may be used of a variety of concave curves running round objects. The word comes from Italian, as a diminutive of cave, from the Latin for "hollow" (it is the same root as cave). A vernacular alternative is "cove", most often used where interior walls curve at the top to make a transition to the roof, or for "upside down" cavettos at the bases of elements.

The cavetto moulding is the opposite of the convex, bulging, ovolo, which is equally common in the tradition of Western classical architecture. Both bring the surface forward and are often combined with other elements of moulding. Usually, they include a curve through about a quarter-circle (90°). A concave moulding of about a full semi-circle is known as a "scotia".

A digital photo frame (also called a digital media frame) is a picture frame that displays digital photos without the need of a computer or printer. The introduction of digital photo frames predates tablet computers, which can serve the same purpose in some situations; however, digital photo frames are generally designed specifically for the stationary, aesthetic display of photographs and therefore usually provide a nicer-looking frame and a power system designed for continuous use.

Digital photo frames come in a variety of different shapes and sizes with a range of features. Some may even play videos as well as display photographs. Owners can choose a digital photo frame that utilizes a WiFi connection or not, comes with cloud storage, and/or USB and SD card hub.
