Photo manipulation

Photos composited and manipulated in an image editing program

Photo manipulation is the application of image editing techniques to photographs in order to create an illusion or deception (in contrast to mere enhancement or correction), through analog or digital means Its uses, cultural impact, and ethical concerns have made it a subject of interest beyond the technical process and skills involved.

For more details on the technical processes involved, see Image editing.

Types of photo manipulation

In digital editing, photographs are usually taken with a digital camera and input directly into a computer. Transparencies, negatives or printed photographs may also be digitized using a scanner, or images may be obtained from stock photography databases. With the advent of computers, graphics tablets, and digital cameras, the term image editing encompasses everything that can be done to a photo, whether in a darkroom or on a computer. Photo manipulation is often much more explicit than subtle alterations to color balance or contrast and may involve overlaying a head onto a different body or changing a sign's text, for example. Image editing software can be used to apply effects and warp an image until the desired result is achieved. The resulting image may have little or no resemblance to the photo (or photos in the case of compositing) from which it originated.

History

Before computers, photo manipulation was achieved by retouching with ink, paint, double-exposure, piecing photos or negatives together in the darkroom, or scratching Polaroids. The 1980s saw the advent of digital retouching with Quantel computers running Paintbox, and Scitex imaging workstations being used professionally. Silicon Graphics computers running Barco Creator became available in the late 1980s which, alongside other contemporary packages, were effectively replaced in the market by Adobe Photoshop running on the Apple Macintosh.

Political and ethical issues

Photo manipulation is as old as photography itself; the idea of a photo having inherent verisimilitude is a social construct. Photo manipulation has been regularly used to deceive or persuade viewers, or for improved story-telling and self-expression. As early as the American Civil War, photographs were published as engravings based on more than one negative.

Joseph Stalin made use of photo retouching for propaganda purposes. On May 5, 1920 his predecessor Lenin held a speech for Soviet troops that Leon Trotsky attended. Stalin had Trotsky retouched out of a photograph showing Trotsky in attendance. Nikolai Yezhov, an NKVD leader photographed alongside Stalin in at least one photograph, was shot in 1940 and subsequently edited out of the photograph. See images altered by Soviet censors for more information.

In the 1930s, John Heartfield used a type of photo manipulation known as the photomontage to critique Nazi propaganda. The pioneer among journalists distorting photographic images for news value was Bernarr Macfadden and his composograph in the mid-1920s.

The style and techniques of modern digital photomontage were anticipated as early as the late 1960s, particularly by the surreal album cover photography of the British design group Hipgnosis.

Some ethical theories have been applied to image manipulation. During a panel on the topic of ethics in image manipulation Aude Oliva theorized that categorical shifts are necessary in order for an edited image to be viewed as a manipulation. In Image Act Theory,Carson Reynolds extended speech act theory by applying it to photo editing and image manipulations. In How to Do Things with Pictures,William Mitchell details the long history of photo manipulation and discusses it critically.

Use in journalism

OJ Simpson magazine covers

A notable case of a controversial photo manipulation was a 1982 National Geographic cover in which editors photographically moved two Egyptian pyramids closer together so that they would fit on a vertical cover. This case triggered a debate about the appropriateness of photo manipulation in journalism; the argument against editing was that the magazine depicted something that did not exist, and presented it as fact. There were several cases since the National Geographic case of questionable photo manipulation, including editing a photo of Cher on the cover of Redbook to change her smile and her dress. Another example occurred in early 2005, when Martha Stewart's release from prison was featured on the cover of Newsweek; her face was placed on a slimmer woman's body to suggest that she will have lost weight while in prison.

Another famous instance of controversy over photo manipulation, this time concerning race, arose in the summer of 1994. After O.J. Simpson was arrested for allegedly murdering his wife and her friend, multiple publications carried his mugshot. Notably, TIME Magazine published an edition featuring an altered mugshot, removing the photograph's color saturation (which some accused of making Simpson's skin darker), burning the corners, and reducing the size of the prisoner ID number. This appeared on newsstands right next to an unaltered picture by Newsweek.

There is a growing body of writings devoted to the ethical use of digital editing in photojournalism. In the United States, for example, the National Press Photographers Association (NPPA) have set out a Code of Ethics promoting the accuracy of published images, advising that photographers "do not manipulate images [...] that can mislead viewers or misrepresent subjects."Infringements of the Code are taken very seriously, especially regarding digital alteration of published photographs, as evidenced in a recent case in which a Pulitzer prize-nominated photographer resigned his post following the revelation that a number of his photographs had been manipulated.

"Photoshopping" or just "Shopping" is slang for the digital editing of photos.The term originates from Adobe Photoshop, the image editor most commonly used by professionals for this purpose; however, other programs, such as Paint Shop Pro, Corel Photopaint, Paint.NET, or the GIMP, may be used. Adobe Systems, the publisher of Adobe Photoshop, discourages use of the term "photoshop" as a verb out of concern that it may undermine the company's trademark.

Despite this, photoshop is widely used as a verb, both colloquially and academically, to refer to retouching, compositing, and color correction carried out in the course of graphic design, commercial publishing, and image editing.

In popular culture, the term photoshopping is sometimes associated with montages in the form of visual jokes, such as those published on the fark.com website and in MAD Magazine. Images may be propagated memetically via e-mail as humor or passed as actual news.An example of the latter category is "Helicopter Shark," which was widely circulated as a so-called "National Geographic Photo of the Year" and was later revealed to be a hoax.
