\nA process or method to confirm that a photograph is what its maker or disseminator claims it to be.[\/vc_column_text][vc_column_text css=”.vc_custom_1689592320745{padding-bottom: 20px !important;}”]Burning<\/strong>
\nA technique used to selectively increase exposure in a section of a photograph. In analog photography, an opaque mask with an aperture or hole of some sort would be used to focus light from an enlarger onto light-sensitized material, usually photographic paper impregnated with silver halide. In digital photography, algorithm-based tools in apps\/programs allow users to achieve these effects.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689592353775{padding-bottom: 20px !important;}”]Camera<\/strong>
\nA device used to capture an image cast on a light-sensitive medium through an aperture or lens.[\/vc_column_text][vc_column_text css=”.vc_custom_1689592397932{padding-bottom: 20px !important;}”]Caption<\/strong>
\nText that accompanies a photograph that customarily includes descriptive information about what is depicted in that image, including people in the photo (if any), the place it was taken, the event depicted, and when it was taken\/made.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689592442454{padding-bottom: 20px !important;}”]Composite(d) Image<\/strong>
\nUsually refers to the combining of two or more photographs to create the illusion of a single one (putting the image of someone\u2019s head on the image of someone else\u2019s body, for example). All reputable news publications forbid such modifications except when the compositing, in the editors\u2019 opinion, should be obvious to the reader. Many publications also require a caption to identify the image as a composite. Sometimes, as stated above, a composited image will be labeled as a photo illustration.[\/vc_column_text]

\"\"<\/div><\/div> <\/div><\/div>[vc_column_text css=”.vc_custom_1689592561191{padding-bottom: 20px !important;}”]Compression<\/strong>
\nAn algorithmic process by which a digital file is reduced in size for storage and transmission.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689592597998{padding-bottom: 20px !important;}”]Computational photography<\/strong>
\nThe term refers both to the use of computer software and hardware to capture and modify digital photographs as well as the process of generating pictures that are not true photographs\u2014images written with light\u2014with software and hardware.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689592635222{padding-bottom: 20px !important;}”]Cropping<\/strong>
\nA technique that involves removing a rectangular sliver from any of a photograph\u2019s four sides. Often this is done to remove what are thought to be irrelevant details or excess space as a way of focusing on an image\u2019s more important aspects. Sometimes, however, important contextual information is removed this way. Cropping, like retouching, predates the use of software and has long been done by hand.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689592679045{padding-bottom: 20px !important;}”]Deepfake<\/strong>
\nA false but realistic picture, video, audio created using digital technology with the purpose of deceiving viewers.
\n[\/vc_column_text]
\"\"<\/div><\/div> <\/div><\/div>[vc_column_text css=”.vc_custom_1689592717202{padding-bottom: 20px !important;}”]Dodging<\/strong>
\nA technique that originated in the darkroom whereby an object is used to block or limit light during enlarging, the process through which light is projected through a negative to create a positive image on a light-sensitized surface such as photo paper.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689592789366{padding-bottom: 20px !important;}”]Generative artificial intelligence<\/strong>
\nA digital system that generates content\u2014pictures, text, audio, video\u2014in response to prompts entered by a user.[\/vc_column_text][vc_column_text css=”.vc_custom_1693469219606{padding-bottom: 20px !important;}”]Image generator<\/span><\/strong>
\nAn image generator is an AI-powered tool that takes input from a text prompt, processes it, and creates an image that best matches the instruction given in the prompt description. An AI text-to-image generator often makes use of a machine learning technique called artificial neural networks that can receive input in the form of words, which it then processes to generate an image.[\/vc_column_text][vc_column_text css=”.vc_custom_1689592858860{padding-bottom: 20px !important;}”]Large-language model<\/strong>
\nAn artificial intelligence system trained on massive datasets that produce texts based on input, prompts entered by a user.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689592878132{padding-bottom: 20px !important;}”]Machine learning<\/strong>
\nA process by which a computer system is trained to produce output in ways that mimic human behavior and then to refine and improve that output the more it is used.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689592919604{padding-bottom: 20px !important;}”]Manipulated photograph<\/strong>
\nOne that has been modified after the image was made as a way of enhancing the impact of the image or explicitly deceiving the viewer. A manipulated photograph may also be one that depicts a staged event as if it were spontaneous. While some manipulations represent an obvious intent to falsify what occurred, the reader must be aware that all photographs represent the interpretations of the photographer and depict situations that often have been affected by his or her presence (a portrait would be one example).
\n[\/vc_column_text]
\"\"<\/div><\/div> <\/div><\/div>[vc_column_text css=”.vc_custom_1689592957010{padding-bottom: 20px !important;}”]Optical photography<\/strong>
\n“Photography,” from the Greek words photos and graphos, means writing or drawing with light. The modifier “optical” indicates the use of a device with an aperture through which light passes to strike a light-sensitive material.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689592979446{padding-bottom: 20px !important;}”]Photo editing<\/strong>
\nThe terms refer to two different processes: the selection of individual photos from a group for particular purposes and the use of computer software and hardware to make changes to the appearance of a photo.[\/vc_column_text][vc_column_text css=”.vc_custom_1693406313588{padding-bottom: 20px !important;}”]Photo illustration<\/span><\/strong>
\nThere are two different meanings. It can be a photograph that is made of a scene that has been staged to illustrate a pre\u00acexisting concept (for example, a group of short people might be asked to laugh or look happy to illustrate the idea that short people have more fun). Or the term can refer to a photograph that is itself later modified so as to illustrate a concept (for example, retouching a pre\u00acexisting photograph of short people so that they appear to be smiling). In the first example the subjects knew what they were being asked to do and presumably consented; in the latter example the changes may have been accomplished without their knowledge. While these are very different strategies, the term photo opportunity is used, even among reputable news organizations, to refer to both.[\/vc_column_text]
\"\"<\/div><\/div> <\/div><\/div>[vc_column_text css=”.vc_custom_1689593042956{padding-bottom: 20px !important;}”]Photo opportunity (photo op) <\/strong>
\nAn event that has been staged in such a way as to be visually appealing to the press. Politicians, celebrities and others are carefully presented in packaged ways, such as showing a politician with his arm around a factory worker, or standing in front of a landmark that reinforces a particular theme. In these situations, professional photographers and videographers are given access that would normally be denied to amateurs. Nearly all news organizations routinely cover photo opportunities, although some try to show them from a different angle or write a caption that allows the reader to understand, at least in a limited way, the degree to which the event has been staged.

\"\"<\/div><\/div> <\/div><\/div>[vc_column_text css=”.vc_custom_1689593078095{padding-bottom: 20px !important;}”]Photorealistic<\/strong>
\nA visual image that resembles a photograph; a picture that looks like it was captured with a camera.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689593094864{padding-bottom: 20px !important;}”]Post-processing<\/strong>
\nProcedures that adjust or change visual elements of a photograph after it has been captured.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689593125101{padding-bottom: 20px !important;}”]Prompt (text prompt)<\/strong>
\nInstructions given to an artificial intelligence system to create content or solve a problem.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689593161338{padding-bottom: 20px !important;}”]Retouched photograph<\/strong>
\nOne that has been partially modified, such as by erasing or adding certain details, darkening or lightening segments, or changing specific colors. Some of these alterations can significantly change the meaning of the photograph (such as by subtracting a liquor bottle from a scene). Most reputable news publications forbid any significant retouching beyond the traditional darkroom techniques of slight darkening or lightening as a way to increase clarity or add some drama. However there is no uniform policy on the treatment of what might be considered minor visual details (such as a pole or a wall outlet in the background); some reputable news organizations may allow them to be erased without informing the reader.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689593238634{padding-bottom: 20px !important;}”]Stage<\/strong>
\nTo create and direct a scene for capture by a camera, often with the intention to deceive viewers.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689593205646{padding-bottom: 20px !important;}”]Sensor<\/strong>
\nA light-sensitized surface that captures light\u2014photons\u2014converts them into electrons, and then data that form a digital image.
\n[\/vc_column_text][vc_column_text css=”.vc_custom_1689593286735{padding-bottom: 20px !important;}”]Straight (or conventional) photograph<\/strong>
\nA visual recording of that which was in front of the lens for a fractional second, or what one might think of as a \u201crecording from appearances.\u201d This is often confused with the truth, but as any photographer will acknowledge, each will see and photograph the same situations in different ways. Photographs, like all other media, are interpretive\u2014whether they are meant to be artistic, documentary or journalistic.[\/vc_column_text][vc_column_text css=”.vc_custom_1693406419651{padding-bottom: 20px !important;}”]Synthetic image<\/span><\/strong>
\nA synthetic image is an image that has been fully or partially created using computer-generated graphics, rather than being captured by a camera.[\/vc_column_text]
\"\"<\/div><\/div> <\/div><\/div>[vc_column_text css=”.vc_custom_1693406267312{padding-bottom: 20px !important;}”]Text to Image Prompt<\/span>
\n<\/strong>Text-to-image artificial intelligence (AI) allows a person to generate an image from scratch based on a text description. The descriptive text entered into an AI image generation tool is called a prompt, which could be a sentence or short phrase giving directions by detailing what type of image the input requires the AI text-to-image generator software to create.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column]
