Introduction[edit]

Wiki commons:

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:

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:

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:

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: My most recent addition (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 window sill or the like), (c) any shake removing function (such as the Sony "steadyshot" function) is deactivated, and (d) the exposure release is activated by a self-timer (here: 10 seconds, although imho 3 seconds would suffice). I will provide a series of images soon which will illustrate the improved resolution.
Note 1: the Sony manual states that the "pixelshift" 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 "pixelshift" (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.

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:

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:

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:

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:

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:

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.

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.

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}}

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.

Template with which to link from one Wikipedia to another[edit]

Caveat: Only works for links to pages (also template, special, etc. pages) within other wikis, but cannot resolve templates which are only defined on that other wiki, such as {{Picture of the day}} defined within the english wikipedia.

Link from wiki commons to the following template description on the the German wikipedia: > [[:{{{1}}}:PageName | Wikipedia auf {{{1}}} ]] Explanation: {{{1}}}=country code, PageName=Page title within the chosen Wikipedia.
- Example 01: Link to page "Taschenuhr" on German Wikipedia
- Example 02: Link to page "Pocket watch" on English Wikipedia

More information[edit]

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. ..."
