{{Short description|Composite image created from two or more photographs}} [[File:Kitrone.jpg|thumb|upright=1.35|Photomontage of kiwifruit and lemons, digitally manipulated using [[GIMP]]]] '''Photomontage''' is the process and the result of making a [[compositing|composite]] photograph by cutting, gluing, rearranging and overlapping two or more photographs into a new image.<ref>{{cite web |url=https://paedia.com/Docs/VIDEO_PHOTOMONTAGE.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://paedia.com/Docs/VIDEO_PHOTOMONTAGE.pdf |archive-date=2022-10-09 |url-status=live |title=Apparatus and Method for Application of Selective Digital Photomontage to Motion Pictures |last1=Clark |first1=Lloyd Douglas |last2=Brown |first2=Brian A.}}</ref> Sometimes the resulting [[Compositing#Physical compositing|composite image]] is photographed so that the final image may appear as a seamless physical print. A similar method, although one that does not use film, is realized today through [[graphics software|image-editing software]]. This latter technique is referred to by professionals as "[[digital compositing|compositing]]", and in casual usage is often called "[[photo manipulation|photoshopping]]" (from the name of the popular software system).<ref>{{cite book |title=Undead Theories: Constructivism, Eclecticism And Research in Education |first=David |last=Geelan |publisher=Sense Publishers |year=2006 |isbn=90-77874-31-3}}</ref> A composite of related photographs to extend a view of a single scene or subject would not be labeled as a montage, but instead a [[stitched image]] or a [[digital image mosaic]]. ==History== Author [[Oliver Grau]] in his book, ''Virtual Art: From Illusion to Immersion'', notes that the creation of an artificial [[immersive virtual reality]], arising as a result of technical exploitation of new inventions, is a long-standing human practice throughout the ages.

The photomontages appeared on street covers all over Berlin on the cover of the widely circulated AIZ magazine published by [[Willi Münzenberg]], Heartfield lived in Berlin until April, 1933, when he escaped to Czechoslovakia after he was targeted for assassination by the SS. Continuing to produce anti-fascist art in Czechoslovakia until 1938, Heartfield's political photomontages earned him the number five position on the Gestapo's Most Wanted List. [[Hannah Höch]] began experimenting with photomontage in 1918. Höch worked for Ullstein Verlag designing knitting and embroidery patterns that were inspired by her photomontage work of the time.<ref>Maria Makela (1996).

Other major artists who were members of Berlin Club Dada and major exponents of photomontage were [[Kurt Schwitters]], [[Raoul Hausmann]], and [[Johannes Baader]]. Individual photographs combined to create a new subject or visual image proved to be a powerful tool for the Dadists protesting [[World War I]] and the interests that they believed inspired the war. Photomontage survived Dada and was a technique inherited and used by European [[Surrealist]]s such as [[Salvador Dalí]]. Its influence also spread to Japan where avant-garde painter [[Harue Koga]] produced photomontage-style paintings based on images culled from magazines.<ref name="eskolahk">{{cite book|last=Eskola|first=Jack|title=Harue Koga: David Bowie of the Early 20th Century Japanese Art Avant-garde|year=2015|publisher=Kindle, e-book}}</ref> The world's first retrospective show of photomontage was held in Germany in 1931.<ref name="Becker2011">{{cite book|last=Becker|first=Lutz|title=Cut & Paste.

In 1985 he even published a book demonstrating and explaining his techniques, two years before [[Thomas Knoll|Thomas]] and [[John Knoll]] began selling Photoshop through Adobe. Ten years later in 1995, Adobe's creative director [[Russel Brown]] tried to get Uelsmann to test out Photoshop. Uelsmann didn't like it, but his wife [[Maggie Taylor]] did, and began using it to produce digital photomontage, becoming a founder of the modern genre. ==Techniques== Other methods for combining images are also called photomontage, such as Victorian "combination printing", the printing of more than one negative on a single piece of printing paper (e.g. [[Oscar Gustave Rejlander|O. G. Rejlander]], 1857), front-projection and computer montage techniques. Much as a [[collage]] is composed of multiple facets, artists also combine montage techniques. A series of black and white "photomontage projections" by [[Romare Bearden]] (1912–1988) is an example. His method began with compositions of paper, paint, and photographs put on boards measuring 8½ × 11 inches. Bearden fixed the imagery with an emulsion that he then applied with hand roller. Subsequently, he photographed and enlarged them. The nineteenth century tradition of physically joining multiple images into a composite and photographing the results prevailed in press photography and [[offset lithography]] until the widespread use of [[digital image editing]]. 20th century [[Xerox]] technology made possible the ability to copy both flat images and three-dimensional objects using the copier as a scanning camera. Such copier images could then be combined with real objects in a traditional cut-and-glue [[collage]] manner. Contemporary photograph editors in magazines now create "paste-ups" digitally. Creating a photomontage has, for the most part, become easier with the advent of computer software such as [[Adobe Photoshop]], [[Paint Shop Pro]], [[Corel Photopaint]], [[Pixelmator]], [[Paint.NET]], or [[GIMP]]. These programs make the changes digitally, allowing for faster workflow and more precise results. They also mitigate mistakes by allowing the artist to "undo" errors. Yet some artists are pushing the boundaries of digital image editing to create extremely time-intensive compositions that rival the demands of the traditional arts. The current trend is to create images that combine painting,<ref>''[[Yuri Rydkin]]'' {{cite web|url=https://syg.ma/@rydkin/v-ramkakh-fotokollazhi|title=WITHIN (photo collages)|work=Sygma|access-date=8 January 2021|archive-date=7 March 2021|archive-url=https://web.archive.org/web/20210307083427/https://syg.ma/@rydkin/v-ramkakh-fotokollazhi|url-status=live}} // Foreword: art critic [[:ru:Даими, Теймур|''Теймур Даими'']], photo artist [[:ru:Василий Ломакин (поэт)|''Василий Ломакин'']], literary critic [[:ru:Зейферт, Елена Ивановна|''Елена Зейферт'']].</ref> theatre, illustration, and graphics in a seamless photographic whole. ==Legal and ethical issues== [[File:BMW M8 GTE endurance race car in front of Tyrolian mountains - photomontage.jpg|thumb|Example for an artificially created, totally misleading image: A race car exhibited at an airport (below) was cropped and combined on a computer with snowy mountains, leading to an image of a situation which never existed.]] [[File:M8 Flughafen München (cropped).jpg|thumb|[[BMW M8 GTE]] endurance race car at [[Munich airport]] in 2021]] {{Further|Derivative work}} A photomontage may contain elements at once real and imaginary. Combined photographs and digital manipulations may set up a conflict between [[aesthetics]] and [[ethics]] – for instance, in fake photographs that are presented to the world as real news. For example, in the [[United States]], the [[National Press Photographers Association]] (NPPA) has 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."<ref>[http://www.nppa.org/professional_development/business_practices/ethics nppa.org] {{webarchive|url=https://web.archive.org/web/20061212074440/http://www.nppa.org/professional_development/business_practices/ethics |date=2006-12-12 }}, NPPA Code of Ethics webpage</ref> ==Scrapbooking == Photomontage also may be present in the [[scrapbooking]] phenomenon, in which family images are pasted into scrapbooks and a collage created along with paper ephemera and decorative items. [[Digital art]] scrapbooking employs a computer to create simple collage designs and captions. The amateur scrapbooker can turn home projects into professional output, such as CDs, DVDs, displays on television, uploads to a website for viewing, or assemblies into one or more books for sharing. ==Photograph manipulation== [[Photograph manipulation]] refers to alterations made to an image. Often, the goal of photograph manipulation is to create another 'realistic' image. This has led to numerous political and ethical concerns, particularly in journalism. <!-- {{Wideimage|Photomontage (Forggensee Panorama).jpg|[[Compositing|Composite]] of 16 photographs that have been digitally manipulated to give the impression that it is a real [[landscape]].
