Bild des Monats: Februar - Unser erster Bildraub...

Bild des Monats: Februar - Unser erster Bildraub...

...den wir natürlich nicht selbst begangen haben. Viel mehr wurden wir zum ersten mal Opfer (zum ersten mal zumindest, soweit wir davon wissen). Obwohl es uns jetzt nicht besonders schlimm erwischt hat, Grund genug mal über die ganze Problematik nachzudenken, aber auch sich über ein offenbar gutes Bild zu freuen, das sich sein Erscheinen in dieser Rubrik damit redlich verdient hat.

Das Bild

Bevor wir zur Thematik des Bilderklaus kommen, ein paar Worte zum Gegenstand an sich. Das Bild entstand bereits 2013 in Australien. Zu sehen ist ein Teil der 12 Apostel, eine bekannte Küstenformation und zugleich Touristenattraktion an der Great Ocean Road, einer bekannten 243km langen Straße entlang der Südküste des Kontinents im Bundesstaat Victoria. Das Motiv findet man zuhauf im Netz, es ist eigentlich nichts besonderes. Wir erreichten den dazugehörigen Aussichtspunkt am Ende eines ereignisreichen Tages pünktlich zum Sonnenuntergang. Die Sonne selbst ist nicht zusehen, man kann aber erahnen, dass sie flach über dem Horizont steht. Stattdessen scheint der Himmel zu glühen und genau das macht die eigentliche Wirkung des Bildes aus und verhilft ihm zu seiner besonderen Lichtstimmung. Darüber hinaus erweckt es den Anschein, als würde hinter dem Betrachter gleich ein mächtiges Gewitter aufziehen (und tatsächlich hat dies dann auch den Versuch einer Langzeitbelichtung mittels ND-Filter vereitelt). Die EXIF-Daten bieten somit auch keine Überraschungen, seien an dieser Stelle aber der Vollständigkeit halber erwähnt: 27mm bei f/5.6, 1/100s und ISO200, fotografiert mit einer Canon EOS 6D samt Canon EF 24-70mm f/2.8 L. Nennenswerte Bearbeitung fand mit Ausnahme der künstlichen Vignettierung tatsächlich nicht statt.

Was war passiert?

Nun zum eigentlichen Aufhänger dieses Beitrags. Der Sachverhalt ist schnell zusammengefasst. Am 27. Januar dieses Jahres posteten wir auf unserem Instagram Profil das Bild wie folgt:

Auf keiner anderen Plattform hatten wir bis zu diesem Zeitpunkt das Bild irgendwie der Öffentlichkeit zugänglich gemacht. Noch am gleichen Tag erschien es dennoch auf der Facebook Seite der Great Ocean Road. Das Bild ist also von Instagram zu Facebook gewandert, und zwar dort auf eine tourismusmarketing-geprägte Seite, die einen zumindest ansatzweise kommerziellen Eindruck macht. Immerhin gibt es ein Impressum mit Adresse und Telefonnummer und jede Menge Posts, die ganz offensichtlich an zukünftige Besucher gerichtet sind. Zudem wurde das Bild in einen zwar nicht schlimmen, aber dennoch so nicht existenten Kontext gebracht ("Long weekend road tripping").

Unser Bild wurde also zumindest im weiteren Sinne kommerziell genutzt, ohne dass von uns irgendwelche Verwertungsrechte eingeräumt wurden. Natürlich kann man den konkreten Wert dieser Nutzung nur schwer bemessen und wir verdienen mit unseren Bildern auch nicht unseren Lebensunterhalt, können das also relativ entspannt sehen. Wir verkneifen uns erst recht eine urheberrechtliche Einordnung über Länder- und Kontinentgrenzen hinweg. Aber ein bisschen geht's hier einfach auch ums Prinzip! Wir würden vorher einfach gerne gefragt werden.

Wie kriegt man überhaupt mit, dass einem ein Bild geklaut wurde?

In unserem konkreten Fall wurden wir immerhin als Quelle verlinkt und haben so eine entsprechende Facebook-Notification bekommen. Das macht das ganze auch noch relativ erträglich. Gefragt werden würden wir trotzdem gerne (wurden wir auch schon, und haben nie nein gesagt). Und solange wir nicht von unseren Bildern leben müssen, werden wir eine Weiterverwendung vermutlich auch immer erlauben. Nicht zuletzt kann das der initiale Kontakt für eine Kooperation sein, die beiden Seiten was bringt!

Wenn man allerdings nicht durch Notifications aufgrund von Verlinkungen in sozialen Netzwerken automatisch benachrichtigt wird, muss man selbst aktiv werden. Das erfordert aber Zeit, die man unter Umständen nicht hat, erst recht, wenn das eigene öffentliche Portfolio sehr groß ist. Ein erster Ansatzpunt kann die Google Bildersuche sein. Ein Klick auf die kleine Kamera im Texteingabefeld erlaubt es einem dort nach konkreten Bildern (statt nach Worten) zu suchen. Mittlerweile gibt es aber auch diverse Webdienste, die sich auf die Aufdeckung von Bilderdiebstahl spezialisiert haben, zumeist aber kostenpflichtig sind. Da wir mangles Erfahrung keine Empfehlungen in dieser Hinsicht geben können, verweisen wir auf eine entsprechende Google Suche zum Thema. Zielgruppe dieser Dienste ist sicherlich in erster Linie auch eher der Berufsfotograf. 

Was kann man dagegen tun?

Im Grunde nicht so viel, zumindest nichts, womit man sich nicht auch selbst ein Stück weit ins eigene Fleisch schneidet. Die folgenden Möglichkeiten bieten sich an:

  • Da wäre zunächst das allseits beliebte Wasserzeichen. Auch wir machen davon regelmäßigen Gebrauch, allerdings weniger als Kopierschutz, sondern um einfach unsere Identität ein wenig mehr zu transportieren. Bei Wasserzeichen stellt sich immer die Frage, wie aufdringlich man sie gestaltet und platziert. Einerseits möchte man, dass sie den Bildeindruck nicht wesentlich verändern, andererseits aber schon, dass sie sie wahrgenommen werden. Man muss also das richtige Maß finden bei dem Gebrauch von Farben (insbesondere bei allem was nicht grau ist), Göße und Position. Je nach Motiv gilt es unter Umständen da individuell zu entscheiden. Beim folgenden Bild aus dem Elbsandsteingebirge haben wir zum ersten mal selbst reichlich Kritik (auf Facebook) für unser Wasserzeichen einstecken müssen, wurden im gleichen Atemzug aber für das Motiv selbst gelobt. Im Nachhinein absolut nachvollziehbar. Da setzte einfach die mit der Zeit zunehmende Blindheit für das eigene Wasserzeichen ein. Ohnehin muss man sich eingestehen: verwendet man das Wasserzeichen als Kopierschutz, sollte man sich darüber im Klaren sein, dass wegstempelm und beschneiden sehr wirksame Gegenmaßnahmen sind, es sei denn, man plaziert sein Wasserzeichen mit einer gewissen Transparenz großflächig im Bild. Das wollen wir persönlich aber aus Gründen der Präsentationsqualität eher vermeiden.
  • Außerdem kann man sich behelfen mit einer geringen Auflösung, die den Bilderklau unattraktiv macht. In der Zeit von hochaufgelösten Retina-Bildschirmen stößt das dem Betrachter aber wahrscheinlich auch sauer auf. Davon abgesehen ist einem vermutlich ja selbst daran gelegen, sein Bild in bestmöglicher Qualität zu zeigen, um den maximalen Eindruck zu erzielen. Ein Blick in die Hilfeseiten von Instagram verrät, dass unser Bild mit einer Bildbreite von maximal 1080 Pixeln geklaut worden sein kann. Das ist relativ wenig, aber auch noch nicht ausreichend störend im Format eines Facebook-Posts.
  • Zu guter Letzt bleibt einem natürlich noch die Möglichkeit seine Inhalte durch Account Privatisierung zu schützen. Instagram Accounts können beispielsweise privat betrieben werden, so dass nur Follower die eigenen Bilder zu Gesicht bekommen können. Bei Facebook kann sie Sichtbarkeit eines Bildes auf den eigenen Freundeskreis beschränkt werden, etc... Davon abgesehen, dass auch das keinen 100%igen Schutz bietet, läuft es dem Ziel seine Bilder der breiten Öffentlichkeit zu präsentieren massiv zuwider, ist also auch nicht zielführend.

Fazit

Wie man sich selbst nun verhalten soll, muss man detailliert nach eigenen Interessen und konkretem Motiv entscheiden. Reichen passive Maßnahmen wie Wasserzeichen? Habe ich die Zeit aktiv nach meinen Bildern auf Seiten dritter zu suchen? Verdiene ich mit Bildern meinen Lebensunterhalt und bin deshalb von Reichweite abhängig? Bin ich tatsächlich bereit im Zweifelsfall rechtliche Schritte zu unternehmen? Das muss letztendlich jeder für sich selbst wissen. Eure Meinungen und Strategien würden uns allerdings stark interessieren! Wir freuen uns dementsprechend wie immer über Kommentare eurerseits (unter diesem Beitrag oder bei Facebook)!

    Why axolotls seem to be everywhere — except in the one lake they call home
    Кракен даркнет
    Scientist Dr. Randal Voss gets the occasional reminder that he’s working with a kind of superstar. When he does outreach events with his laboratory, he encounters people who are keen to meet his research subjects: aquatic salamanders called axolotls.

    The amphibians’ fans tell Voss that they know the animals from the internet, or from caricatures or stuffed animals, exclaiming, “‘They’re so adorable, we love them,’” said Voss, a professor of neuroscience at the University of Kentucky College of Medicine. “People are drawn to them.”

    Take one look at an axolotl, and it’s easy to see why it’s so popular. With their wide eyes, upturned mouths and pastel pink coloring, axolotls look cheerful and vaguely Muppet-like.

    They’ve skyrocketed in pop culture fame, in part thanks to the addition of axolotls to the video game Minecraft in 2021. These unusual salamanders are now found everywhere from Girl Scout patches to hot water bottles. But there’s more to axolotls than meets the eye: Their story is one of scientific discovery, exploitation of the natural world, and the work to rebuild humans’ connection with nature.

    A scientific mystery
    Axolotl is a word from Nahuatl, the Indigenous Mexican language spoken by the Aztecs and an estimated 1.5 million people today. The animals are named for the Aztec god Xolotl, who was said to transform into a salamander. The original Nahuatl pronunciation is “AH-show-LOAT”; in English, “ACK-suh-LAHT-uhl” is commonly used.
    Axolotls are members of a class of animals called amphibians, which also includes frogs. Amphibians lay their jelly-like eggs in water, and the eggs hatch into water-dwelling larval states. (In frogs, these larvae are called tadpoles.)

    Most amphibians, once they reach adulthood, are able to move to land. Since they breathe, in part, by absorbing oxygen through their moist skin, they tend to stay near water.

    Axolotls, however, never complete the metamorphosis to a land-dwelling adult form and spend their whole lives in the water.

    “They maintain their juvenile look throughout the course of their life,” Voss said. “They’re teenagers, at least in appearance, until they die.”

    Broken spheres
    Dyson died in 2020 before any of his spheres could be found — although they are just one of a dozen ideas that bear his name.
    kra30at
    “As a young scientist, Dyson showed that three competing quantum theories were actually the same theory — he summarily ended the competition,” said William Press, the Leslie Surginer Professor of Computer Science and Integrative Biology at the University of Texas at Austin. He was not involved in the study. “Later, he applied his genius to areas of astronomy, cosmology, the extraterrestrial realm, and also the very real problem of nuclear proliferation here on planet Earth. At the time of his death, he was recognized as a provocative and creative thinker.”

    George Dyson also attested to his father’s fascination and comprehensive reach across disciplines.
    https://kra30att.cc
    kra30 at
    “Taking advantage of a short attention span and an aversion to bureaucracy, he contributed to five fields of mathematics and eleven fields of physics, as well as to theoretical biology, engineering, operations research, literature, and public affairs,” the younger Dyson said. “Many of his ideas were controversial, with one of his guiding principles being that ‘It is better to be wrong than to be vague.’”

    The approach of the researchers behind the new study could offer a more fruitful path in the search for extraterrestrial intelligence, said Tomotsugu Goto, an associate professor of astronomy at the National Tsing Hua University in Taiwan. He also was not involved with the study.

    “However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. “Authors argue that the debris disks around (dwarf stars) are rare, but the 7 candidate authors selected out of 5 million sources are also rare. Despite this, the seven candidates warrant further investigation with powerful telescopes for a more definitive evaluation.”

    Axolotl problems
    As Mexico City grew and became more industrialized, the need for water brought pumps and pipes to the lake, and eventually, “it was like a bad, smelly pond with rotten water,” Zambrano said. “All of our aquatic animals suffer with bad water quality, but amphibians suffer more because they have to breathe with the skin.”
    лаки джет играть
    To add to the axolotls’ problems, invasive fish species such as carp and tilapia were introduced to the lake, where they feed on axolotl eggs. And a 1985 earthquake in Mexico City displaced thousands of people, who found new homes in the area around the lake, further contributing to the destruction of the axolotls’ habitat.

    These combined threats have devastated axolotl populations. According to the International Union for Conservation of Nature, there are fewer than 100 adult axolotls left in the wild. The species is considered critically endangered.

    While the wild axolotls of Lake Xochimilco have dwindled to near-extinction, countless axolotls have been bred for scientific laboratories and the pet trade. “The axolotl essentially helped establish the field of experimental zoology,” Voss said.

    In 1864, a French army officer brought live axolotls back to Europe, where scientists were surprised to learn that the seemingly juvenile aquatic salamanders were capable of reproduction. Since then, scientists around the world have studied axolotls and their DNA to learn about the salamanders’ unusual metamorphosis (or lack thereof) as well as their ability to regrow injured body parts.
    In addition to their role in labs, axolotls have become popular in the exotic pet trade (though they are illegal to own in California, Maine, New Jersey and Washington, DC). However, the axolotls you might find at a pet shop are different from their wild relatives in Lake Xochimilco. Most wild axolotls are a dark grayish brown. The famous pink axolotls, as well as other color variants such as white, blue, yellow and black, are genetic anomalies that are rare in the wild but selectively bred for in the pet trade.

    What’s more, “most of the animals in the pet trade have a very small genetic variance,” Zambrano said. Pet axolotls tend to be inbred and lack the wide flow of different genes that makes up a healthy population in the wild. That means that the axolotl extinction crisis can’t simply be solved by dumping pet axolotls into Lake Xochimilco. (Plus, the pet axolotls likely wouldn’t fare well with the poor habitat conditions in the lake.)
