My Activities within the Wiki Universe[edit]

I am Franz van Duns. My main user page is on Wiki Commons.

  • My Wiki user name spelled out in Cyrillic letters: Франц ван Дунс (provided by tt.wikipedia.org).


Recent Uploads[edit]

List of images that I have recently uploaded. As time passes older uploads will be removed from this section. All images are to be found in the sections following the introduction.


Introduction[edit]

Wiki commons:

Longines pocket watch, model 4 Grand Prix, 1900ff, rear view, clockwork visible - enhanced resolution

Just over a year ago I joined Wiki Commons, and have learned a lot since then. The dos and don'ts directly from the community, many technical facts concerning the inner works of Wiki itself by picking up multiple bits of code and further information from the numerous pages I have visted.

  • Before that date I had spent many evenings screening through reams of both Wikipedia and Wiki Commons pages ever since their inception at the turn of this century.
  • The technical facts and a slew of interesting links I have discovered en route are all documented in the tables on the latter part of this, my user page.
  • I will continue to provide materiél and live up to my aim to give back some of the joy and wisdom I have before so freely received from others.

Donating images:

An age-worn door latch and a rusted padlock fastened to well-weathered planks - original image taken on Kodachrome 25 colour reversal film in Dötlingen, Germany, May 1980

Thus I seek to contribute selected photographs to the global community. Photographs as allowed by German law, depicting mostly living and inanimate objects of nature. All derived from digital and analogue stocks of mine.

Experience: I have accumulated 50+ years of experience as a photographer, 46 years with ever improving single lens reflex camera systems. I have experimented with multiple lighting arragements, and various image editing programmes, but have till this day not once shared any of my photographs with any other persons than my family, closest friends, and, of course, the many wedding couples I have depicted. This state of encapsulation shall now end!

Exa outfit: My first single lens reflex camera was an East-German-built Exa body, purchased in 1972. Two lenses were sufficient: 50mm and 135mm. Started off with negative films, later colour slides.

Canon FD / Leica outfits:

Canon 15mm f2.8 SSC fisheye lens and its original satchel

I still own an extensive set of Canon FD lenses, all prime, and A-1 / AE-1 bodies, ranging from a 15mm fish eye lens to a 500mm mirror telescopic lens, all purchased in the early 1980'ies. The 50mm, 80mm and 100mm macro lenses provide the best quality. Marriage added a substantial set of Leica bodies and prime lenses. This analogue outfit has served me well right up to approx. the year 2010, but did not allow true HDR nor focus stacking, and only imperfect panoramas.

Olympus E10 outfit: My first digital camera was an Olympus E10, sporting a small sensor with an impressive count of 4 megapixels and a fixed zoom lens.

Sony Alpha 7R / Canon FD adapter: Come 2014 with the introduction of the Sony Alpha 7R body. The ideal camera for me, as I could attach all my lenses via adapter to the Sony body. Now high-resolution stereo photography, HDR (high dynamic range), high-resolution focus stacking, highly detailed macro photography, and quasi-perfect panoramas were within reach.

Sony Alpha 7RII / Zeiss lenses:

Sigma 135mm F1.8 DG HSM A Canon EF lens & compatible Sigma MC-11 Mount adapter

Very soon it became clear that the 1.8/55mm Zeiss prime lens I had purchased with the body was way better than the previously used Canon FD 55mm 1.2 lens. Since then I have purchased both a Sony Alpha 7RII with a built-in stabiliser, a set of Zeiss Batis prime lenses (1.8/85mm, 2/25mm, 2.8/18mm) plus a Zeiss/Sony 2.8/90mm macro G OSS prime lens. Most recent addition: a Sigma 1.8/135mm DG prime lens plus Sigma Canon EOS to Sony E lens adapter.
All these modern lenses provide the superb quality required for large-scale crops, especially in combination with the sturdy (and heavy) tripod I have been using regularly ever since purchase in 1980. But take note that the bokeh effect with the old but proven FD lenses is in general far more pleasing than the (multiple) rings visible within the bokeh circles one can attain with modern aspherical lenses.


The Sony Alpha 7RII body sports a sensor resolution of 42 megapixels. The image size is 7952x5304 pixels.

Sony Alpha 7RIII: Purchased on 8th July, 2019: a Sony Alpha 7RIII body. I have updated the camera software and am still customising the various branches within the extensive set of primary settings. First attempts with the Sony's "pixelshift" function have met with success, provided that (a) the object to be imaged is absolutely immobile, (b) the camera is set on a very stable base (a brick, a window sill or the like), (c) any shake reducing function (such as the Sony "Steady Shot" function) is deactivated, and (d) the exposure release is activated by a self-timer (here: 10 seconds, although imho 3 seconds usually suffice). I will provide a series of images soon which will illustrate the improved resolution.
Note 1: the Sony manual states that the "Pixel Shift" function deactivates the shutter to eliminate all shaking and activates the electronic shutter instead.
Note 2: the pixel count of 42 megapixels remains the same, but as the sensor moves through 4 positions programmed for "Pixel Shift" (initial position > then up > right > down) the Bayer colour pattern moves in sync (i.e., green > red > green > blue). Thus each pixel is supplied with all three RGB colours (albeit 2x green) and the resulting image need not be averaged over overlapping blocks of 4 pixels, but will depict every single pixel in its individual glory. Sounds strange, but works very well provided all factors contributing to even the slightest movement have been fully eliminated.

Sony Alpha 7RIV: My most recent addition (October 2019): a Sony Alpha 7RIV body. The sensor sports 61 MPixels. This is extremely useful for huge enlargements.
Took great pains to understand the additional features of this camera and others of the Sony Alpha 7RIII I simply hadn't tried out before. Initially on the basis of the original Sony manual, but that was simply a description of what the technical terms mean. Far more helpful were a number of explanatory videos I discovered by searching the web. Both the Sony Alpha 7RIII and Sony Alpha 7RIV now have identical settings, as far as applicable, of course.

Historical Cameras:

In the course of the past 30 years I have collected some 30 historical cameras.

  • One of the oldest is a sturdy SLR body, manufactured from 1928-1936 with an internal 3 1/4" (83 mm) x 2 1/4" (58 mm) mirror in a roughly cubic outer shape.
    It sports a collapsible leather viewer rising to a height of 5,5" (142 mm).
  • The other cameras range from Minox-sized to folding bellows cameras that take 6 cm x 9 cm roll films.

I intend to supply high-quality images of all cameras within my collection.

Digitising:

An age-worn door latch and a rusted padlock fastened to well-weathered planks - original image taken on Kodachrome 25 colour reversal film in Dötlingen, Germany, May 1980.

I am currently digitising the best of my slides and negatives. I have so far uploaded one digitised slide, taken on Kodachrome 25 reverse film (ISO 25 diafilm), see below. I intend to provide more historically interesting or high-quality photographs derived from slides, negative films or black and white films.

Panoramas:

The Amtshaus (communal town hall) of Aplerbeck, a suburb of Dortmund, Germany in extreme detail. Also participated in wiki commons challenge March 2019 - Town halls

Panoramas up to 7952 pixels wide are created by simply cropping a suitable image. Larger panoramas (with a higher pixel count and/or multi-row) are created by stitching more than one intersecting image via specialised software. I have been using a multitude of Adobe Photoshop versions for this purpose since 1999.

Focus stacking:

Beginning and end: A well-formed needle following a single groove from its fixed starting point provides a stream of music all along its inevitable track toward the record's natural inner termination. A tribute to the classic record player.

Having loosely experimented with focus Stacking software since 2012, I have in the past 4 years delved into the finesses of the software product Zerene Stacker Pro. Following up a series of thorough testing with objects of varying size, depth and complexity, also in comparison with the product Helicon Focus, I finally purchased Zerene Stacker Pro in mid-2018. High resolution focus stacks are mostly taken in sheltered quarters, but are also attainable outdoor with the camera steadied on an tripod if the subject remains motionless due to lack of wind.

Macro:

Tigridia pavonia - wilted overnight - 2018-07-25 composite image via focus stacking (German: Tigerlilie - über Nacht verwelkt), magnification ratio 1:1.3.

A Macro photograph is a close-up image of a subject. In the early days of photography a ratio of 1:10 or less on full frame film was considered "macro", i.e. subject height 240mm or less. Nowadays macro imaging closes up on 1:1 (subject height 24mm), beginning somewhere in the vicinity of 1:3. The image on the right sports a magnification ratio of 1:1.3 at full frame. i.e the whole height of the image was approx. 31mm.

Stereo:

Two Passiflora caerulea flowers arranged as a stereo image pair, Dortmund, June 2019. Quality image

The two images of the stereo pair usually sport an offset by 50-65mm between viewpoints. If combined with macro photography the spacing between viewpoints is often reduced to 20-30mm as more will strain the untrained viewer's ability to combine the images. I prefer the crosseye-viewing method that swaps the placing of the left and right eye images so that they will be correctly seen cross-eyed, the left eye viewing the image on the right and vice versa, the intended stereo image appearing in between.

HDR: I have yet to find a suitable software to correctly process HDR images. The software products I have used so far more often than not tend to introduce strange colouring effects and unnatural fringes. I thus have discontinued this technique since 2016 and have taken resort to processing uncompressed RAW files whenever possible, as the Sony Alpha 7RII sensor can discern slightly more than 10 aperture values of dynamic range at ISO 100, which are subsequently stored as 14 bit RAW values. Maybe the HDR situation has improved meanwhile and is worth another try.

Combining techniques / stereo: I have also experimented with combinations of the above techniques: focus stacking of panoramas, panorama HDRs, macro stereo sets comprising two focus stacks. Not all are represented in the files I have uploaded to Wiki Commons this far.

Images Created by Pixel Shift[edit]

The Pixel Shift technology has been implemented by a number of manufacturers. The sensor of the Sony Alpha 7R III retains its original count of 42 megapixels (61 Mpixels for the Sony Alpha 7R IV), but as the sensor moves through 4 positions (initial position > then up > then right > then down as seen on the final image) the Bayer colour pattern moves in sync (i.e., green > red > green > blue). Thus each pixel is supplied with all three RGB colours (albeit 2x green) and the resulting image need not be averaged over overlapping blocks of 4 pixels, but will depict every single pixel with its full colour potential. Works very well provided all factors contributing to even the slightest movement have been fully eliminated. The Sony Alpha 7R IV sports an enhanced version with a 16 half-pixel Pixel Shift movement.

External Usage of my Images[edit]

At least one of my images appears on one of the following non-wiki sites.

  • NOTE 1: Discovered these images by painstakingly seeking for instances of my user name "Franz van Duns" (and plausible variations) on various web search sites.
  • NOTE 2: Up to the day I undertook this web exploration, 2020-12-28, I had uploaded merely 74 photographical images (disregarding .SVG and purely explanatory images).
    • I consider it a great acknowledgement that a grand total of 13 of these images (i.e. on average one of six) are currently in use on wiki-external websites.
    • I must, of course, also emphasize that this extent of external image usage is a grand tribute to Wikimedia Commons as a source of high-quality and thus commercially and privately viable images.
    • In fact, this was my intent from the very day I registered at Wikimedia Commons that I would upload images for free use that adhere to the highest standards an advanced amateur could possibly provide. More images upcoming ...

Commons:Valued Images[edit]

Difference between quality images, featured pictures, and valued images:

Note: the following text was extracted from page Commons:Valued images:

  • The quality images project aims to identify and encourage users who provide images of high technical quality to Commons.
  • Featured pictures are the cream of the crop at Commons and the project is reserved for images of both extraordinary value and technical quality.
  • Valued images, on the other hand, are those that are the most valuable of their kind for use in an online context, within other Wikimedia projects.
  • The technical requirements for valued images are typically much lower, as there is no concern about suitability for print usage. A built-in camera in a modern mobile phone should be sufficient if the subject is of high value and the photo illustrates it well at a viewing size of 480×360 pixels or equivalent.
  • Valued images are less about technical quality and more about your ingenuity in finding good and valuable subjects which matter, and about the usability of the information on the image page.

Commons:Valued images   >   contains rules regarding nomination as a valued image.

Inter-Wiki Communication Template - Methods A[edit]

Wikimedia user groups

Communication

Help:Notifications

Help:Notifications/Thanks

Inter-Wiki Communication Template - Methods B[edit]

Found a simple, concise method to send a simple "thank you" to another wiki user.

   Method 1: via talk pages. 
   Method 2: send a "thanks for editing" in the edit history of files and wiki commons pages.
   Method 3: Using template Reply to, described as follows as Method C. 

Inter-Wiki Communication Template - Method C[edit]

{{Reply to|user-name}}[edit]

Aliases: ping, replyto, mention

Usage

This template takes advantage of the new user mention notification to ping the user(s) you are replying to in a discussion (so you don't have to use the {{talkback}} template).
It works on any talk page or Project namespace page. It also works on the Support Desk.

This template is particularly helpful in discussions that are not threaded, to indicate which user's comment is referenced. If you feel that this template unnecessarily personalizes the discussion, you may still use the {{talkback}} template on the user's talk page to indicate that you have replied to a comment.

Note that it isn't necessary to use this template to ping (indicate) the user if you are already linking to their username from your post.

Single recipient[edit]

To use it, just add something like the following to an existing discussion:

{{reply to|User1}} Exemplary message text. ~~~~

For example, ":{{reply to|user-name}} Message text." displays as:

   @user-name: Message text.

The comment must be signed and belong to a section in order for the notification to work.

Multiple recipients[edit]

You can reply to up to 5 people at once:

{{reply to|User-1|User-II|User-C}} Message text. ~~~~

Aliases[edit]

   {{ping}}
   {{replyto}}
   {{mention}}

Including Icon in a Link[edit]

Trying to include the miniaturised Wikipedia icon (20x20px) in a link to Wikipedia from within Wikimedia Commons.

I can place the icon before or after the link, but, as yet, not inside the link, where it would be underlined together with the link text.

Uploading mishaps[edit]

Image notes / annotations do not appear

  • Problem: Image notes / image annotations won't show up since a new version of the image was uploaded.
  • Check: Check whether the image dimensions have changed, this is sometimes barely perceptible.
  • Reason: The positions of image notes are strictly linked to the image's dimensions. This is to prevent wrong positioning if someone changes the image size, even by simply one single pixel.
  • Possible causes: Any tilt / perspective correction of your image after your initial upload could reduce or sometimes even slightly enlarge image size.

Display Image Crop without Actually Cropping[edit]

Template:CSS image crop
From Wikipedia, the free encyclopedia
Jump to navigation
Jump to search
Template documentation[view] [edit] [history] [purge]

{{CSS image crop}} creates a crop of an image inline for previewing the look and feel of a page, or for linking to full images when a slight crop is preferred in an article, but the full image is more encyclopaedic in general. Where only a small section of the image is used after the crop, it's best to upload the crop as a new file, to avoid sending the extra image data to users.
{{CSS image crop
|Image         = The Name of the image file, or may accept {{Annotated image}}.
|bSize         = The Base Image width in pixels (the image we are cropping on)
|cWidth        = Crop Image Width in pixels
|cHeight       = Crop image Height in pixels
|oTop          = Offset Top in pixels, optional and defaults to 0 when omitted
|oLeft         = Offset Left in pixels, optional and defaults to 0 when omitted
|Location      = 'right', 'left', 'center' or 'none'. Determines placement of the image on the page
                 Defaults to 'right' when description is provided (as is default for thumb images)
                 When description is blank, location on left (as is default for non-thumbs)
|Description   = Description (will render out using thumbnail class)
|Link          = Name of an article to be linked by clicking on the image (omit unless there is a
                 good reason to link to an article instead of the image).
|Alt           = The alt text for the image.
|Page          = The page of the file, if there are multiple pages (such as pdf files).
|magnify-link  = The image to be linked by the magnify icon (Use if the Image parameter is set to
                 {{Annotated image}} or the Link parameter leads to something other than the image).
}}

  • One question for which, despite having done a lot of searching, I am still trying to find an answer: on which page within wikipedia do I find the basis of the claim that an image must have been included within a wikipedia article for at least 7 days before it may be proposed as a "Featured picture"?
    • Eureka! Have found the relevant site: Wikipedia:Featured picture criteria
      • Advance to criterion no. 5:   "Adds significant encyclopedic value to an article ..."
      • Read bullet no. 1:   "... It is preferable to wait a reasonable period of time (at least 7 days) after the image is added to the article before nominating it. ..."

Wiki Commons Structured Data[edit]

Collection of Wikidata Queries on Franz van Duns' Wikidata user page:

What is Structured Data?[edit]

  • Whenever an image has been uploaded to Wikimedia Commons and after the appropriate file information has been provided, a request appears asking you to provide so called "structured data".
  • Structured data has a well-defined structure, which sets off from simple statements, but may also be combined to amazingly complex statements.
    • Most (all?) structured data is stored in the Wikidata database.
    • Each "item = noun " and "property = verb" used to create structured data has a key number.
    • The noun "farmhouse" e.g. has a key number of Q489357.
    • The verb "depicts" e.g. has a key number of P180.

First Encounter with Structured Data[edit]

  • First choice for images is the "depicts" statement, which is the default statement provided for new entries.
  • If your image displays a horse galloping across the yard in front of a farmhouse, you will at least provide the following statements by typing the catchword into the input field and press the [ENTER] kay:
    • horse [ENTER]
      Choose the correct entry from the dropdown list, i.e. horse   domesticated (work) animal [ENTER]
    • Repeat for other terms applicable to the "depicts" statement:
    • farmhouse [ENTER]
      farmhouse   chief dwellings attached to farms, ... [ENTER]
    • yard [ENTER]
      yard   area of land ajacent to a building ... [ENTER]
    • gallop [ENTER]
      gallop   gait of a horse [ENTER]
  • Close data entry by clicking on [Publish changes] or discard changes by clicking on [Cancel].

Where to View Structured Data[edit]

  • Once a Wikimedia Commons entry has been stored, you will find the "Structured data" tab to the right of the "File information" tab. Click on tab to reveal the list of already stored structured data and allow adding editing.
  • NOTE: Wikimedia Commons adds a certain number of data overnight. The following items are extracted from the file information you initially provided:
    • Creator, copyright status, copyright license, source of file, inception, and coordinates of the point of view.
  • You will find the key number for an item by hovering over the catchword in the list.
    • horse => d:Special:EntityPage/Q726
    • farmhouse => d:Special:EntityPage/Q489357
    • yard => d:Special:EntityPage/Q1623185
    • gallop => d:Special:EntityPage/Q1766807

How to add additional entries to Structured Data List[edit]

  • The above example was kept very simple and will suffice for most purposes.
  • Should a full description require more than just a "depicts" statement, you must find the appropriate property to match your needs.
    • Finding the correct verb is not a trivial process!
  • To add a new structured data item scroll down to the end of the list and click on the button [+ Add statement].
  • The input field that now unfolds sports looking glas icon and the phrase "earch to add properties (part of, media type, etc.) from Wikidata".
  • As you type in the desired property the search engine displays up to six of the best-matching suggestions.
    • NOTE 1: The phrase "part o" does not display the same list of matches as the phrase "part of" does.
    • NOTE 2: Trailing blanks are ignored, but the phrase "part of" with two blanks between characters matches nil.
    • NOTE 3: When you type in a statement that already exists in the list, you are shown only a blank drop-down list, but not, as one would normally assume, a warning stating such as "Please avoid creating duplicate entries".

How to find additional entries to Structured Data List[edit]

  • The following properties require at least one additional so called "item", which in turn may require at least one so called "qualifier".
  • Only "items" with special connection properties are allowed, but one may seemingly choose a multitude of items, of wich, alsas, only very few are eligible.
    • E.g. one may add the "item" "plant" to the statement "part of", but after a few seconds a lightning bolt icon appears, which, when hoverering over, states "This statement has some issues". By clicking on this icon an explanation appears, e.g. "Issues / allowed entity types constraint / The property 'part of' should not be used on this type of entity, the only valid entity type is 'Wikibase item'.".
    • On the other hand, the item "camera" is allowed, although it is certainly not the object the depicted subject "plant bud" is a part of!
  • On the whole, the treatment of statements that go beyond the most simple statements is a very tricky business, and, at least for me, is a matter of trial and error.


  • Information about property "part of"
    • part of [ENTER]
      part of   object of which the subject is a part (...). Inverse property of "has part" (P527, see also "has parts of the class" (P2670)). [ENTER]
    • part of => d:Special:EntityPage/P361


  • Information about property "media type"
    • media type [ENTER]
      IANA-registered identifier for a file type (MIME). [ENTER]
    • part of => d:Special:EntityPage/P1163

Specific Examples[edit]

How to add camera data to Structured Data List[edit]

  • Information about property "image captured with"
    • image captured with [ENTER]
      part of   object of which the subject is a part (...). Inverse property of "has part" (P527, see also "has parts of the class" (P2670)). [ENTER]
    • part of => d:Special:EntityPage/P4082
    • Note: Accepted items are:
      • Sony α7R IV (Q65976324), camera (), model series (), and surely more ..., but not a lens such aus "Canon MP-E 65mm f/2.8 1–5x Macro lens". The lens model is accepted at first, but an exclamation mark icon appears within seconds that states "This statement has some issues". By clicking on this icon an explanation appears, "Potential issues / value type constraint / Values of 'image captured with' statements should be instances of one of the following classes (...), but ... currently isn't: camera model, model series, cell phone model".
      • And as only one camera was employed in the making of this image, one should choose the exact camera make "Sony α7R IV".

How to add lens data to Structured Data List[edit]

This is accomplished in two steps:

  • First by adding the property "connects with" to the above created "Sony α7R IV" (which in turn is enable via the property "image captured with").
  • Second by adding a specific lens, such as "Canon MP-E 65mm f/2.8 1–5x Macro lens" into the "sub-qualifier" input field just beside on the right.


  • Information about property "connects with"
    • connects with [ENTER]
      connects with   item with which the item is physically connected [ENTER]
    • connects with => seemingly, no key number specified (d:Special:EntityPage/Pnnnnn)!
    • Enter lens name:
      • To the right of the property "connects with" is an input field that accepts a specific lens, such as "Canon MP-E 65mm f/2.8 1–5x Macro lens".
      • Entering the phrase "canon mp" suffices to whittle down the selection to a single entry in the drop-down list, which you must now click on to accept as the desired entry.


  • Close data entry by clicking on [Publish changes] or discard changes by clicking on [Cancel].

How to add fabrication method and specific "Manufacturer" to Structured Data List[edit]

This is accomplished in four steps:

  • (a) statement "fabrication method".
  • (b) item "focus stacking".
  • (c) qualifier "manufacturer".
  • (d) item "Zerene Stacker" (doesn't exist, thus click on button "..." and choose "No value exists for this property"). But comparable item "Helicon Focus" (Software) exists.


  • Information about statement "fabrication method"
    • fabrication method [ENTER]
      fabrication method   item with which the item is physically connected [ENTER]
    • fabrication method => d:Special:EntityPage/P2097


  • Information about item "focus stacking"
    • focus stacking [ENTER]
      focus stacking   digital image processing technique [ENTER]
    • focus stacking => d:Special:EntityPage/Q1435078


  • Information about qualifier "manufacturer"
    • manufacturer [ENTER]
      manufacturer   item with which the item is physically connected [ENTER]
    • manufacturer => seemingly, no key number specified (d:Special:EntityPage/Pnnnnn)!


  • Information about item "Zerene Stacker"
    • Zerene Stacker [ENTER]
      Zerene Stacker   software producer [ENTER]
    • Zerene Stacker => d:Special:EntityPage/Qnnnnnn (yet to be defined)
    • Remedy: click on button "..." and choose "No value exists for this property".


  • Close data entry by clicking on [Publish changes] or discard changes by clicking on [Cancel].

How to add location data to Structured Data List[edit]

This is accomplished in two steps:

  • First by adding a new statement: either (a) "location" or (b) "located in the administrative territorial entity".
  • Second by adding one or more specific territorial entities, such as in (a) "Aplerbeck" and in (b) both "Dortmund" and "Germany".


  • Information about property "location"
    • location [ENTER]
      location of the object, structure or event. ... other ... [ENTER]
    • location => d:Special:EntityPage/P276


  • Information about property "located in the administrative territorial entity"
    • located in the administrative territorial entity [ENTER]
      the item is located on the territory of the following administrative entity. ... other ... [ENTER]
    • located in the administrative territorial entity => d:Special:EntityPage/P131


Yet to explore[edit]

The following structured data elements remain to be explored as to within which context they may be used:

  • Statement "photos by lens used" (Q63633670)
  • Statement "participant in"
  • Statement collection for "creator":
    • "object has role: photographer"
      (qualifier) role or generic identity of the value of a statement ("object") in the context of that statement; For the role of the item the statement is on ("subject"), use P2868.
    • "subject has role: photographer"
      role/generic identity of the item ("subject"), also in ther context of a statement. For the role of the value of the statement ("object"), use P3831 ("object has a role"). For acting roles, use P453 ("character role"). For persons, use P39.
    • NOTE: "subject has role: photographer" prvokes a "Potential issues" warning:
      allowed qualifiers constraint: "subject has role" is not a valid qualifier for "creator" - the only valid qualifiers are:
      • possible creator
      • workshop of
      • follower of
      • circle of
      • manner of
      • forgery after
      • school of
      • after a work of
      • sourcing circumstances
      • named as
      • ...

Providing Proof of Valid License[edit]

  • Use template {{PD-scan|PD-old-100}} as proof of valid license for the following constellation:
 This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason: This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 100 years or fewer.

Public domain

This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 100 years or fewer.


Dialog-warning.svg You must also include a United States public domain tag to indicate why this work is in the public domain in the United States.


This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.

Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
