Wikimedia Commons explicitly permits the hosting of photographs that carefully reproduce a two-dimensional public domain work; such photographs are in the public domain in the United States, where this site is based (if you are a Commons contributor, see 共享資源:何時使用PD-Art標籤 for more information on this policy). However, there may be local laws that prevent or restrict the reuse of such images in your country, some of which are listed below. While we hope this information will be helpful, any use of such content is at your own risk, and you should consider securing legal advice in your jurisdiction before using content.
Neighbouring rights ("simple photographs")
In certain countries, any photograph, whether original or not, is covered by a so-called "simple photograph" neighbouring right that amounts to a copyright with a reduced term of protection. If the photo is sufficiently original, the author can additionally be granted normal copyright protection. In the Nordic countries, for example, the right applies to all photographs, including "faithful reproduction" images. However, protection does not normally apply to scans or other photomechanical reproductions — this special neighbouring right applies only to photographs. See Commons:Copyright rules/Photographs.
Inconclusive. Court cases in Australia have gone both ways. See Telstra v Desktop Marketing Systems.
Inconclusive. In the Belgian law "Wet betreffende het auteursrecht en de naburige rechten." of 30 June 1994, in chapter 1, part 1, article 2, paragraph 5 one finds:
De beschermingstermijn van foto's die oorspronkelijk zijn, in de zin dat zij een eigen intellectuele schepping van de auteur zijn, wordt (vastgesteld) overeenkomstig de voorgaande paragrafen.
The protection duration of photographs that are original, in the sense that they are a proper intellectual creation of the author, becomes like previous paragraphs. [and thus copyrighted till 70 years after the death of the author]
The Belgian federal government clarifies this on one of its websites:
Worden daarentegen niet beschermd door het auteursrecht: wat uitsluitend door een machine wordt voortgebracht (satellietbeelden).
There is no copyright protection for what is made solely by a machine (e.g. satellite images).
Simple scans or photographs of public domain documents remain hence in the public domain.
Inconclusive. Court cases in Canada regarding "sweat of the brow" have gone both ways.
Inconclusive. Court cases in France have gone both ways. See fr:Utilisateur:Jastrow/PD-art (in French).
OK in most cases.
German law distinguishes between photographic works (1) and simple photographs (2), which, in principle, are protected under a neighbouring right; however, simple photographs of "works of visual art" in the public domain are not protected. Simple scans or photocopies are never protected (3). Wikimedia Commons-hosted images of two-dimensional public domain artwork usually fall into the second category. Therefore, the reuse of such material is typically unproblematic.
(1) Photographic works: While definitive guidance from the courts is lacking, it is widely assumed by legal scholars and practitioners alike that the faithful photographic reproduction of a "flat" object generally does not attract protection as a photographic work. In the same vein, the Stuttgart Court of Appeals noted in a 2017 decision that the panel could not find "any substantial use of artistic creativity" in a professional museum photographer's pictures of paintings (although the Court ultimately did not decide the question).
(2) Simple photographs: In general, German copyright law also protects simple photographs that do not rise to the leval of a photographic work due to their lack of originality. However, following a EU Directive, the German Copyright Act was amended, effective 7 July 2021, in an effort to exclude certain photographs of public-domain material from protection as simple photographs. The current legal situation is thus as follows:
Simple photographs of works of visual art in the public domain are not protected. Neither the German Copyright Act nor the EU Directive that prompted the new provision give a definition of the term "works of visual art". In the official reasoning provided with the (at the time: proposed) amendment, the German government notes that it understands the term to match a similar term used in another EU Directive, where "visual works" are explained as including "fine art, photography, illustration, design, architecture, sketches of the latter works and other such works that are contained in books, journals, newspapers and magazines or other works". Materials that are not "works of visual art" may include manuscripts and music sheets. Because the provision refers to works of visual art, it only applies to pictures of material that is an author's own intellectual creation, ie material that, in the abstract, could be eligible for copyright protection, as opposed to, say, paintings created by an elephant. Notably, the exception does not specifically require that the depicted work must have enjoyed protection at any time; accordingly, the Government points out that simple photographs of paintings from the 16th century are also unprotected. Also according to the official reasoning, the exclusion from protection applies to simple photographic reproductions irrespective of whether they were created before or after 7 July 2021. It does not apply to reproductions that constitute photographic works.
Simple photographs that are not exempt from protection as per the preceding paragraph enjoy protection until 50 years after their first publication; if a simple photograph is not published within 50 years following its creation, its protection ends at that point.
(3) Unprotected photographs: Purely mechanical reproductions are not protected. Examples given in the literature are images resulting from the use of a photocopying machine or a document scanner.
OK before 2002 / Not OK otherwise. Reproduction photography is protected by copyright in Italy, but this right subsists until 20 years have elapsed from the year in which the picture was produced.
OK The Agency for Cultural Affairs states photographic reproductions are not copyrightable, though there have been no court decisions. As a similar case, The Intellectual Property High Court ruled that a hand-drawn copy of an old line drawing with minor modifications could not attract copyright as a derivative work because of lack of creativity.  And The Supreme Court did not admit owner to exercise of Copyright.
OK Paragraph 4 of Article 1 of Decree-Law n.o 43/99/M: "A work is original where it is the result of the author’s own creative effort and not merely the appropriation of another person’s creation."
OK The Netherlands transposed the CDSM-directive. Unless the material resulting from that act of reproduction is original in the sense that it is the author's own intellectual creation a work of art will remain in the public domain if its underlying work is the public domain (following from article 14 of the CDSM Directive.
Even thought the Netherlands did not transpose article 14 in a new article of the Dutch copyright act, the Ministry did clarify  (page 8, last paragraph):
"Het verstrijken van de beschermingstermijn van werken van beeldende kunst leidt ertoe dat die werken tot het publieke domein gaan behoren. Die werken mogen vrijelijk worden hergebruikt. Artikel 14 van de richtlijn bevestigt dit en bepaalt dat reproducties van werken van beeldende kunst niet door het auteursrecht worden beschermd. Dit is slechts anders wanneer de reproducties als zodanig ook weer een werk in de auteursrechtelijke betekenis van het woord opleveren. Daarvoor is noodzakelijk dat er sprake is van een originele schepping die het persoonlijk stempel van de maker draagt. Voor getrouwe reproducties, waarbij bijvoorbeeld kan worden gedacht aan een foto van een schilderij ten behoeve van een ansichtkaart, zal dit doorgaans niet het geval zijn. Voor cultureel erfgoedinstellingen is het auteursrecht dan geen beletsel voor verkoop van zulke ansichtkaarten. De verspreiding van getrouwe reproducties van werken in het publieke domein draagt bij tot de toegang tot en de bevordering van cultuur. Artikel 14 is geheel in lijn met het geldende recht en behoeft daarom geen omzetting."
English: "The expiry of the term of protection for works of visual art means that these works become part of the public domain. Those works may be freely reused. Article 14 of the Directive confirms this and provides that reproductions of works of visual art are not protected by copyright. This is only different if the reproductions as such also result in a work in the copyright sense of the word. For this it is necessary that there is an original creation that bears the personal stamp of the maker. This will generally not be the case for faithful reproductions, such as a photo of a painting for a postcard. For cultural heritage institutions, copyright does not prevent the sale of such postcards. The dissemination of faithful reproductions of works in the public domain contributes to the access and promotion of culture. Article 14 is fully in line with applicable law and therefore does not require transposition."
Generally Not OK. In Denmark (), Finland (), Norway (), Sweden (), and Iceland (), anyone who has produced a photographic picture has an exclusive right to reproduce the picture and to make it available to the public. This right subsists until 50 years have elapsed from the year in which the picture was produced (15 years after the death of the photographer but at least 50 years in Norway).
Photographic reproductions from these countries enter the public domain when both the copyrights on the original and this neighboring right on the photograph have expired. Recent photos are thus never OK, but older ones may be (if the original is in the public domain). These countries had until the 1990s shorter terms for this photography right.
- Iceland: OK before January 1, 1972. Iceland has a term of 50 years since creation.
- Norway: OK before January 1, 1970 if the photographer died before January 1, 1980 Norway had a term of 25 years since creation (but at least 15 years after the death of the photographer) until 1995. If the photographer died later or the picture was taken later, the current terms apply.
- Sweden: OK before January 1, 1969. Sweden had a term of 25 years until 1994.
- Finland: OK if created before January 1, 1972 or published before January 1, 1966. Finland had a term of 25 years since the year of first publication until 1991.
- Denmark: OK before January 1, 1970. Denmark had a term of 25 years until 1995. (§91, 5 in the current law).
However, mechanical reproduction such as photocopying and scanning are not mentioned in the laws, and are probably OK. Similarly, reprints using old etchings and copper-plates are likely not protected.
OK Faithful reproductions of two-dimensional works of art are not eligible for copyright themselves under Polish law, because they are not considered as individual creative activity.
- Sąd Apelacyjny w Warszawie, orzeczenie z 5 lipca 1995 (I ACr 453/95)
- Sąd Najwyższy — Izba Administracyjna, Pracy i Ubezpieczeń Społecznych, orzeczenie z 26 czerwca 1998 (IPKN 196/98)
OK Copyright is granted only to "any changes to an artistic work which require creative intellectual work", while "non-essential changes, additions, cuttings or adaptations, as well as the correction of a work or a collection do not extend their copyright term".
Probably OK. Copyright on photographs requires "author’s own intellectual creation" (Act No. 185/2015, Section 3(1)(5)):
(5) Fotografickým dielom je zachytenie obrazu prostredníctvom fotografického technického zariadenia, ak je výsledkom tvorivej duševnej činnosti autora; žiadne iné podmienky podľa odseku 1 sa neuplatnia.
OK before 1997 / Not OK otherwise. The Ley de propiedad intelectual (LPI 1996) provides 25 years of copyright to "mere photographs" or similar reproductions, beginning on 1 January of the year following creation.
TITULO V: La protección de las meras fotografías.
Artículo 128. De las meras fotografías.
Quien realice una fotografía u otra reproducción obtenida por procedimiento análogo a aquélla, cuando ni una ni otra tengan el carácter de obras protegidas en el Libro I, goza del derecho exclusivo de autorizar su reproducción, distribución y comunicación pública, en los mismos términos reconocidos en la presente Ley a los autores de obras fotográficas.
Este derecho tendrá una duración de veinticinco años computados desde el día 1 de enero del año siguiente a la fecha de realización de la fotografía o reproducción.
OK In Switzerland, photographs must exhibit an "individual expression of thought" to be subject to copyright. According to applicable Supreme Court case law this requires that the photograph is given an individual character e.g. by the choice of framing, the use of camera settings or the editing of the image. This means that faithful reproduction photographs are not subject to copyright in Switzerland. The State Library of Lucerne also opines in that sense, saying that photographic reproductions of documents from libraries were not "works" in the sense of the copyright law and thus not copyrighted.
See also Swiss copyright law.
中華民國臺灣地區有部分作品 Not OK：
Article 79 of the Copyright Act: "For a literary or artistic work that has no economic rights or for which the economic rights have been extinguished, a plate maker who arranges and prints the said literary work, or in the case of an artistic work, a plate maker who photocopies, prints, or uses a similar method of reproduction and first publishes such reproduction based on such original artistic work, and duly records it in accordance with this Act, shall have the exclusive right to photocopy, print, or use similar methods of reproduction based on the plate."
Getting this exclusive plate right requires official registration. Once registered, the plate right is good for ten (10) years from the time the plate is completed, to expire at year end.
Cultural Heritage Preservation Act: Item 1 of Article 69: "For the purpose of research and promotion, public antiquities preservation agency (institution) may reproduce and supervise the reproduction of the Antiquities under its custody. Third parties may not make any such reproduction except with the permission and under the supervision of the original custodian preservation agency (institution)."
Item 2 of Article 69: "The rules governing the reproduction and supervision of Antiquities referred to in the preceding paragraph shall be prescribed by the central competent authority."
Item 1 of paragraph 1 of Article 97 provides the administrative fine of 100,000 to 500,000 new Taiwan dollars for "reproducing publicly owned Antiquities without permission from, or supervision of, the original custodian preservation agency (institution) in violation of item 1 of Article 69."
While Turkey recognizes the sui generis right for databases, Article 6/11 on the Law of Intellectual and Artistic Works (Fikir ve Sanat Eserleri Kanunu, FSEK) clearly states: "... However, the protection provided in here can't be extended for the protection of data and materials inside the database"
However, on some cases the "sweat of the brow" doctrine also applies and the copyright protection may be granted on the basis of economic, cultural, social and scientific functions even if it doesn't carry originality but requires effort.
Furthermore, Article 6/5, 6/6 and 6/7 of the FSEK gives protection for corpuses and the arrangement of selected works.
Other photographic reproductions
Article 6/8 of the FSEK states: "... Ordinary transcriptions and facsimiles that are not a product of a scientific research and work is ineligible [for protection]." However, Article 6/3 of the FSEK makes clear that the filming or conversion to a shape that is suitable for transmission via radio and television of musical, artistic, scientific and literature works is eligible for copyright.
The courts in the UK traditionally applied a very low test for photographic originality, based on the "skill and labour" required to capture the image, and it was long thought that there would most likely be sufficient originality in a photographer's selection of lighting arrangements, exposure, filters and so on for a new copyright to be generated. However, the 2009 Infopaq decision of the CJEU defined a different test, namely "Is it the author’s own intellectual creation?"
In November 2015, the UK IPO updated its copyright advice notice to include the following:
- Are digitised copies of older images protected by copyright?
- Simply creating a copy of an image won’t result in a new copyright in the new item. However, there is a degree of uncertainty regarding whether copyright can exist in digitised copies of older images for which copyright has expired. Some people argue that a new copyright may arise in such copies if specialist skills have been used to optimise detail, and/or the original image has been touched up to remove blemishes, stains or creases.
- However, according to the Court of Justice of the European Union which has effect in UK law, copyright can only subsist in subject matter that is original in the sense that it is the author’s own ‘intellectual creation’. Given this criteria, it seems unlikely that what is merely a retouched, digitised image of an older work can be considered as ‘original’. This is because there will generally be minimal scope for a creator to exercise free and creative choices if their aim is simply to make a faithful reproduction of an existing work.
Although the IPO advice is not binding on the UK courts, it is of useful persuasive value. It's interesting that the official view being taken is that the European Court of Justice has effectively replaced the very low bar of "Was sufficient skill and labour applied?" with the higher one of "Is it the author’s own intellectual creation?".
Note that there is no issue regarding raw unenhanced scans or photocopies of PD illustrations in an old book. These are always OK, as purely mechanical copying has never been capable of creating a new copyright.
OK Under the rule in Bridgeman Art Library v. Corel Corporation, a mere 'record' photograph of a 2D work of art (i.e. a photograph which is an as-accurate-as-possible copy of the original) acquires no copyright protection.
The U.S. case of Bridgeman v. Corel (1999)
In Bridgeman Art Library v. Corel Corp. (1999), the New York District Court held that "a photograph which is no more than a copy of a work of another as exact as science and technology permits lacks originality. That is not to say that such a feat is trivial, simply not original". In spite of the effort and labor involved in creating professional-quality slides from the original works of art, the Court held that copyright did not subsist as they were simply slavish copies of the works of art represented. While the New York District Court does not hold jurisdiction over the whole US, other district courts have generally relied on and expanded on this decision.
The rule therefore excludes from copyright protection photographs which are intended to be no more than a faithful reproduction of a two-dimensional work of art such as a painting. If only technical expertise is involved (to take a faithful and unimaginative picture), the photograph acquires no copyright protection in its own right. The case extends the rule that scans and photocopies of two-dimensional originals are not copyrightable to cover in addition faithful reproductions created in the U.S. through photography.
As a result of this case, anyone taking in the U.S. a mere 'record' photograph of a 2D work of art—plain, full-framed—gets no copyright protection for the photograph. If the original work of art is sufficiently old that its own copyright has expired, the photograph itself will then be free for use in the U.S.
Different countries apply the rules on originality in different ways, and identical images may be treated differently in different jurisdictions. In some countries (such as the UK) faithful reproduction images may be considered sufficiently original to attract copyright protection; in others (such as the Nordic countries) there may be neighbouring rights that apply.
