Introduction[edit]
Wiki commons[edit]
Not quite three years ago I joined Wiki Commons, and have learned such a lot since. The dos and don'ts directly from the community, a host of technical facts concerning the inner workings of Wiki itself by picking up multiple bits of code and lots of 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 have added a few user subpages filled with descriptions and hints concerning technical details of some of the methods I currently employ when taking images and subsequent computer-based processing.
- 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[edit]
- I will continue to contribute selected photographs to the global community, explicitly relinquishing all rights except for my basic authorship rights in accord with the Creative Commons Attribution-Share Alike 4.0 International license .
- These images contain subjects or themes as allowed by German law, depicting mostly living and inanimate objects of nature. All derived from digital and analogue stocks of mine.
- All images presented on this page are of my own making, even a few of the icons. This is also in strict accord with current legal regulations in German that makes one susceptible to paying 4-figure fees in euros to the lawful holder of an image's rights (plus all lawyer's fees) for each and every non-licensed image one dares to present on an internet site. Images recently uploaded to Wikimedia Commons that brandish the Creative Commons Attribution-Share Alike 4.0 International license are usually free for use in Germany, but one must take heed of any comments regarding usage restrictions stated on the image's Wiki Commons page.
Experience[edit]
- I have accumulated 50+ years of experience as a photographer, 50 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.
Camera Bodies[edit]
Exa outfit[edit]
- 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 switched to colour slides, alas, 40 years later completely faded.
Canon FD[edit]
- I still own an extensive set of Canon FD mount lenses, all prime, ranging from a 15mm FD fish eye lens to a 500mm FD mirror telescopic lens, all purchased in the early 1980'ies.
- The 50mm, 80mm and 100mm macro lenses provide the best image quality, way better than necessary for analog negative and slide films and perfectly rendering every detail on Ilford Pan F 25ASA black and white film.
- Two Canon A-1 (one technically dead due to a water pouring incident) and three AE-1 bodies and 6 Vivitar electronic flashes complete this outfit.
- 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.
Leica[edit]
- Marriage added a substantial set of Leica bodies and prime lenses.
Olympus E10[edit]
- My first digital camera was an Olympus E10, sporting a small sensor with a then impressive count of 4 megapixels and a fixed zoom lens.
Sony Alpha 7R[edit]
- When the Sony Alpha 7R was first advertised in photographical magazines, what immediately incited me was this singular feature that one could attach almost any lens to the camera body by means of a lens adapter.
- In 2014 I purchased a Sony Alpha 7R body in combination with a 1.8/55mm Sony Zeiss prime lens.
- The ideal camera for me, as I could attach not only all my Canon FD lenses via a Novoflex Canon FD to EF adapter to the Sony body but also all my wife's Leica lenses.
- With an absolutely astounding sensor resolution of 36 megapixels ultra high-resolution images, high-resolution stereo photography, 33%-50% crops, even 66% crops were feasible, HDR (high dynamic range), highly detailed macro photography, first attempts at high-resolution focus stacking, and quasi-perfect panoramas were now all within reach.
- Very soon it became clear that the 1.8/55mm Zeiss prime lens I had purchased with the body was in all respects way better than the previously used Canon FD 55mm 1.2 lens.
- The top-notch computer I had purchased in 2011 was the perfect companion for processing the resulting large digital image files when upgraded to 32 gigabytes RAM.
Sony Alpha 7R II[edit]
- In 2016 I purchased a Sony Alpha 7R II body because it contained a built-in stabiliser, which is a hugh boon when taking images free-handed.
- After having read numerous test reports I purchased the following objectives at my local retailer: Zeiss Batis prime lenses (1.8/85mm, 2/25mm, 2.8/18mm) and 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 and a Sony 200-600 zoom lens.
All these modern lenses provide the superb quality required for large-scale crops, especially in combination with the sturdy (and heavy) Gitzo metal 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 7R III[edit]
- Purchased a Sony Alpha 7R III body in July 2019.
- 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 newly introduced "pixelshift" function were successful, 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: 5-10 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 7R IV[edit]
- My most recent addition (October 2019): a Sony Alpha 7R IV 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 concise 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[edit]
- 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[edit]
- 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[edit]
- Panoramas up to 9504 (Sony Alpha 7R IV) / 7952 (Sony Alpha 7R III) pixels wide are created by simply cropping a suitable image. Larger panoramas (with a higher pixel count and/or multi-row panoramas, see 2x2 panorama of building on the right) are created by stitching intersecting images via specialised software. I currently process panoramas with the extremely reliable Adobe Photoshop Panorama function.
- Even on close scrutiny at 100% resolution panoramas consisting of multiple rows of images are in most cases flawlessly combined into the resulting panoramic image, provided all image borders overlap by 15-20%.
- Stitching errors do occur in some circumstances when repetitive patterns in front of a bland background, such as parallel cut marks in a stone, extend over neighbouring images; not only across the the overlapping area, but also into the area depicted by only one of the images. In such a case neighbouring cuts may be connected, producing dangling "half-cuts" at either end.
- I have continually used regular updates of Adobe Photoshop for this purpose since 1999.
Focus stacking[edit]
- 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.
- Followed 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 outdoors with the camera steadied on an tripod if the subject remains motionless due to lack of wind.
Macro[edit]
- 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 full frame macro imaging closes up on 1:1 (subject height 24mm), beginning somewhere in the vicinity of 1:3.
- I now possess a collection of 3 modern variable and fixed macro lenses that sport a full frame magnification ratio of up to 5:1, resulting in a subject height of 4.8 mm that fills a full frame sensor.
This is on the verge of microphotography (10:1 and more). - 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 (24mm * 1.3).
Microscopy[edit]
- In April 2021 I purchased this microscope lens: Mitutoyo M-Plan Apo 5x.
- The copy of the Mitutoyo M-Plan Apo 2x microscope lens I purchased in May 2021 had to be returned because it was was severely maladjusted with defocussed edges and highly vignetted corners.
- Mitutoyo microscope lenses are attached to the camera body via a Novoflex Micro-Tube which contains an apochromat lens and is affixed to adapters at both ends. The M26-lens adapter connects to the lens and the Novoflex A to E-mount adapter connects to the camera body.
- The above setup is rigidly held by a Novoflex rack, which again is attached to a Novoflex CASTEL-MICRO motorised focusing rack. ...
- First test runs with the Mitutoyo M-Plan Apo 5x lens, comprising focus stacks of 300-450 61 megabit-sized images attained at 13 micrometer steps have provided highly pleasing results. No, I haven't uploaded an image yet. Will do so soon.
Stereo[edit]
- 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[edit]
- 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[edit]
- 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 combinations are represented in the files I have uploaded to Wiki Commons this far.

Images Created by Pixel Shift[edit]
- A number of manufacturers have implemented a method commonly known as "pixel shift" (often concatenated as "pixelshift").
Refer to the following Wikipedia article containing information about the > Pixel Shift technology. - Description of Pixel Shift method as deployed by my Sony camera bodies:
the Sony sensor rapidly moves through 4 neighbouring positions, taking an image at each position. As seen on the final image the movements are: initial position > then up > then right > then down, thus covering all colours of the embedded Bayer colour pattern, i.e., green > red > green > blue. When these four overlapping images are combined each pixel of the resulting image contains information about each of the three RGB colours (albeit 2x green) and will thus depict every single pixel with its full colour potential. This method also eliminates the resolution approximation required by the standard Bayer pattern because every pixel of the final image contains the full resolution information.
The sensor of the Sony Alpha 7R III retains its original count of 42 megapixels (61 Mpixels for the Sony Alpha 7R IV).
The Sony Alpha 7R IV sports an enhanced version with a 16 half-pixel Pixel Shift movement that leads to an image sized 244 Mpixels.
The Pixel Shift method works very well provided all factors contributing to even the slightest movement have been fully eliminated.

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, mainly on Google and on Yahoo.
- NOTE 2: Up to this follow-up web exploration on 2021-11-19, I have uploaded a carefully chosen set of 87 photographical images.
- On my first explorative tour-de-force on 2020-12-28, I had by then uploaded 74 images (disregarding .SVG and purely explanatory images), of which 13 had found use on various wiki-external websites.
- Eleven months later I have detected 4 more images displayed on external websites, summing up to 17 files. Also discovered that six of the initial images have been included on further websites.
- I consider it a great acknowledgement that a grand total of 17 of these images (i.e. almost one in five) are currently regarded as fit for 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 absolutely free use that adhere to the highest standards an advanced amateur could possibly provide. More images upcoming, slowly but surely, ...

Inter-Wiki Communication Template - Methods A[edit]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).
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}} Referencing / Displaying Images[edit]
