The choice of the field of view can have a strong effect, effectively 'censoring out' other parts of the scene, accomplished by cropping them out or simply not including them in the photograph. This even touches on the philosophical question of what reality is. The human brain processes information based on previous experience, making us see what we want to see or what we were taught to see. Photography does the same, although the photographer interprets the scene for their viewer.

s and tables. The term ''business graphics'' came into use in the late 1970s, when personal computers became capable of drawing graphs and charts instead of using a tabular format. Business graphics can be used to highlight changes over time.
Advertising
Advertising is one of the most profitable uses of graphics; artists often do advertising work or take advertising potential into account when creating art, to increase the chances of selling the artwork.
Most importantly, graphics give a good look to artwork whenever it is applied. Graphics contribute to the general outlook of a designed artwork, this, in turn, lure interested members of the public to look at the work of art or purchasing it.
Any graphical work (especially advertisement) or any work of art that is poorly designed will not persuade the audience. therefore, for an advertisement to persuade and convince readers or viewers, it must be well designed with needed graphical tools so as to bring profit to the designer or advertiser.

Educational animation is an important emerging field of graphics. Animated graphics have obvious advantages over static graphics when explaining subject matter that changes over time.
The ''Oxford Illustrated Dictionary'' uses graphics and technical illustrations to make reading material more interesting and easier to understand. In an encyclopedia, graphics are used to illustrate concepts and show examples of the particular topic being discussed.
In order for a graphic to function effectively as an educational aid, the learner must be able to interpret it successfully. This interpretative capacity is one aspect of graphicacy.
Film and animation
Computer graphics are often used in the majority of new feature films, especially those with a large budget. Films that heavily use computer graphics include The Lord of the Rings (film series), ''The Lord of the Rings'' film trilogy, the Harry Potter (film series), ''Harry Potter'' films, ''Spider-Man (2002 film), Spider-Man'' and ''War of the Worlds (2005 film), War of the Worlds''.
Graphics education
The majority of schools, colleges, and universities around the world educate students on the subject of graphic design and art.
The subject is taught in a broad variety of ways, each course teaching its own distinctive balance of craft skills and intellectual response to the client's needs.
Some graphics courses prioritize traditional craft skills—drawing, printmaking, and typography—over modern craft skills. Other courses may place an emphasis on teaching digital craft skills. Still, other courses may downplay the crafts entirely, concentrating on training students to generate novel intellectual responses that engage with the brief. Despite these apparent differences in training and curriculum, the staff and students on any of these courses will generally consider themselves to be graphic designers.
The typical pedagogy of a graphic design (or graphic communication, visual communication, graphic arts or any number of synonymous course titles) will be broadly based on the teaching models developed in the Bauhaus school in Germany or Vkhutemas in Russia. The teaching model will tend to expose students to a variety of craft skills (currently everything from drawing to motion capture), combined with an effort to engage the student with the world of visual culture.
Noted graphic designers
Aldus Manutius designed the first italic type style which is often used in desktop publishing and graphic design. April Greiman is known for her influential poster design. Paul Rand is well known as a design pioneer for designing many popular corporate logos, including the logo for IBM, NeXT and United Parcel Service, UPS. William Caslon, during the mid-18th century, designed many typefaces, including ''ITC Founder's Caslon'', ''ITC Founder's Caslon Ornaments'', ''Caslon Graphique'', ''ITC Caslon No. 224'', ''Caslon Old Face'' and ''Big Caslon''.
