Primary Sources: Visual Materials Photographs, film, video, paintings, drawings, cartoons, prints, designs, and three-dimensional art such as sculpture and architecture are examples of visual materials that can be classified as fine art or documentary record. These items were created at the time they were observed. As such, they provide a unique glimpse into history because we never see life as it is now; we see it as it was then.
Secondary Sources: Oral histories, memoirs, professional journals, newspapers, magazines, online resources such as Wikipedia, social media sites like Facebook and Twitter, and research papers based on these sources are all considered secondary materials.
Tertiary Sources: Any writing not categorized as primary, secondary, or reference material is considered tertiary source material. For example, letters, emails, and texts messages are tertiary sources because they cannot be directly observed by another person. Secondary sources often include interviews with people who were involved in an event, such as a crime or trial.
Quaternary Sources: Data sets such as statistical reports, maps, and graphs are quaternary sources. They can only reveal their existence through observation.
Painting, drawing, printing, sculpture, pottery, photography, video, filmmaking, design, crafts, and architecture are examples of visual arts. The word "visual" here refers to the fact that these are all art forms in which you can see what you're doing.
Media is a short form for medium. These are tools used by artists to express themselves. The most common media are paint, pen, pencil, ink, printmaking, clay, stone, and wood. However, artists often use more than one medium in their work. For example, an artist may use paint, paper, and thread to create a piece of artwork.
Visual artists use technology to produce their works of art. They may use computers, including desktop PCs, laptop computers, and tablet computers; smartphones, including iPhone, Android, and Windows Phone devices; and even watchmakers' tools (such as laser cutters) to create images or products using computer-aided design (CAD).
Artists also use technology to display their works. They may use websites, social networking sites, such as Facebook and Twitter; online marketplaces, such as Etsy and Pinterest; and mobile applications, such as Instagram, to distribute their creations to a wider audience.
Digital and printed pictures, photography, graphic design, fashion, movies, architectural constructions, and fine arts are all examples of visual media. Billboards, cellphones, newspapers, screen projectors, posters, televisions, computers, and a variety of other mediums and gadgets display visual media.
The term "visual media" includes anything that can be seen by humans and that uses visual images as its source material. This includes written words, drawings, paintings, sculptures, fiber art, and any other visual representation used to communicate information.
Digital photos are data stored in a computer that represent images. The two main types of digital photographs are RAW files and JPEG files. A RAW file is the original photo data stored on a camera memory card in its native format. It requires special software to view its contents and may not be altered without losing its quality. A JPEG file is a compressed version of a photo taken with a digital camera. It contains enough information for a photographer to reproduce or edit the image but not enough to be considered an original piece of data.
Photography is the process of recording light or other electromagnetic radiation into the elements of a photographic film or sensor. The technology was invented by German scientist Carl von Linde in 1839. Modern photography typically uses chemicals produced from silver salts to create an image on paper or another medium. Before this technology was developed, images were created using glass plates or zinc sheets with dyes dissolved in them.
