Tagebau Welzow

Tagebau Welzow

Vor einiger Zeit hatte ich die Gelegenheit im Braunkohle-Tagebau Welzow fotografieren zu können. Als Teil einer geführten Geländewagen-Tour war es möglich in Bereiche vorzudringen, die dem Beobachter von den offiziellen Aussichtspunkten verborgen bleiben. 

Das Betriebsgelände ist nur in Verbindung mit einer gebuchten Tour zugänglich. Dazu gehören auch Jeep-Touren, die von örtlichen Tourismusorganisatoren durchgeführt werden. Im Geländewagen ist es dann relativ problemlos möglich die ansonsten nicht passierbaren Abfahrten hinein in den Tagebau zu meistern. Der Tagebau Welzow fördert täglich 50k Tonnen Braunkohle, die zu 2/3 direkt in das benachbarte Kraftwerk gespeist werden, zu Spitzenzeiten lässt sich die Förderleistung auf 100k Tonnen hochschrauben. Das eigentliche Kohleflötz hat nur eine Mächtigkeit von 10 bis 15 Metern, darüber befindet sich aber das Deckgebirge von 90 bis 150 Metern, das als Abraum erst mal beseitigt werden muss. Dementsprechend groß ist das Abbaugebiet und die darin befindlichen Maschinen.

Aus fotografischer Sicht war es mir primär wichtig die Weitläufigkeit des Abbaugebietes einzufangen. Um eine geeignete Bildwirkung zu erzielen muss ein Bildelement vorhanden sein, über das der Betrachter die tatsächliche Größe einschätzen kann. Geeignet dafür sind Objekte, deren Größe man aus dem Alltag kennt, z.B. ein Bagger, eine Hütte oder eine Schiene. Natürlich eignen sich für diese Art Bilder besonders Weitwinkelobjektive, um möglichst viel von der Landschaft ins Bild zu pressen. Als Nebeneffekt nimmt auch der Himmel entsprechend viel Platz ein und verstärkt bei geeigneter Textur noch den Eindruck der Tiefe im Bild. Geeignete Textur bedeutet in dem Fall, dass er nicht einfach einfarbig blau oder grau sein sollte, sondern Wolken vorhanden sein müssen, die sich möglichst gut einzeln abgrenzen. Das Beispielbild wurde mit dem 14mm Walimex f2.8 gemacht und liefert am Vollformat schon einen enorm großen Bildausschnitt. Der orange Versorgungszug übernimmt die Rolle des Maßstabsgebers, dem Betrachter wird auch ohne die exakte Größe des Zuges zu kennen sofort klar, wie riesig die Flächen sein müssen im Bild. Unterstützt wird dieser Effekt natürlich auch von der Linienführung: Alle Grabenwände laufen auf einen gemeinsamen Fluchtpunkt am Horizont zu, der Betrachter wird quasi gezwungen dem Graben in der Mitte zu folgen.

Sehr interessant sind im Tagebau auch die verschiedenen Farben und Strukturen, die entstehen. Der Abraum besteht weitestgehend aus Sand, der durch den Absetzer wieder aufgeschichtet wird. Entsprechend anfällig ist die so neu geschaffene Landschaft für Erosion. Insbesondere Regen schwemmt viel Boden aus und erzeugt so sehr interessante Sandformationen. Der Sand hat keine einheitliche Farbe, da auch er in verschiedenen Epochen der Erdgeschichte abgelagert wurde (man darf nicht vergessen, dass diese gigantischen Bagger in Sekunden Millionen Jahre Erdgeschichte umgraben). Spannend sind auch die Farben, die durch den sogenannten "Lausitzer Ocker" gebildet werden. Leider handelt es sich dabei eigentlich um ein massives Umweltproblem, das in der Umgebung von Tagebaugebieten zur Bedrohung für Pflanzen und Tiere geworden ist.

Die Lichtverhältnisse waren leider nicht optimal. Alle Bilder sind in der Mittagszeit entstanden bei durchgehend grauem Himmel. Entsprechend flau sahen viele der Bilder out of cam aus. Mit der entsprechenden Kontrastanpassung in Lightroom ließ sich aber der Dynamikumfang der Bilder deutlich erhöhen, so dass im Himmel wieder einzelne Wolken erkennbar waren und die wenigen Farben im Tagebau wieder etwas mehr zu leuchten begannen. Der Workflow dabei ist für mich immer recht ähnlich. Die Tiefen/Lichter-Regler werden genutzt, um möglichst viel Restinformation aus den RAWs rauszuholen, nicht selten werden beide Regler fast bis zum Anschlag (Tiefen hoch, Lichter runter) gezogen. Um dann das Histogramm wieder zu strecken, nutze ich die Regler für weiß und schwarz und achte darauf, dass keine Bereiche ausbrennen oder unterbelichtet werden. Etwas Klarheit bringt dann noch den nötigen Mikrokontrast und verstärkt die Farben etwas im Bild.

    Europe’s secret season for travel starts now
    kraken войти

    Summer might be the most popular season for tourism to Europe, but it hardly promises a calm, cool and collected experience.

    Who can forget this summer’s protests against overtourism in Barcelona and Mallorca, the wildfires that raged across Greece during the country’s hottest June and July on record and selfie stoplights to help control crowds on the clogged streets of Rome and Florence?

    For travelers looking to avoid all that — as well as break less of a sweat literally and financially — welcome to Europe’s secret season.

    From roughly mid-October to mid-December, shoulder season for travel to Europe comes with fewer crowds, far more comfortable temperatures in places that skew scorching hot during the summer months and plunging prices on airfare and accommodation.

    Plunging prices
    “The cheapest time to fly to Europe is typically from about the middle point of October to the middle point of December,” said Hayley Berg, lead economist at travel platform Hopper. “Airfare prices during those eight or nine weeks or so will typically be about an average of 40% lower than prices in the peak of summer in June.”

    Hopper’s data shows that airfare to Europe from the United States during the period between October 20 and December 8 is averaging between $560 and $630 per ticket — down 9% from this time last year and 5% compared to the same timeframe in 2019.

    I am really loving the theme/design of your web site. Do you ever run into any browser compatibility problems? A couple of my blog visitors have complained about my site not working correctly in Explorer but looks great in Chrome. Do you have any recommendations to help fix this problem?

    Director Jon M. Chu missed ‘Wicked’ premiere to welcome fifth child
    кракен магазин

    “Wicked” director Jon M. Chu couldn’t attend the film’s premiere in Los Angeles, and the reason is quite “wonderful.”

    Chu shared on his Instagram Stories that he and his wife Kristin Hodge welcomed their fifth child on Saturday, writing that he “can’t believe this happened while the movie is premiering.”

    “Magic is in the air,” he wrote, sharing a photo of Hodge holding their newborn daughter.

    He added a note to his new addition: “Welcome to our world, you’re gonna do great. You have a lot of witches on your side.”

    “Wicked” stars singer Ariana Grande and Oscar-nominated actress Cynthia Erivo star as witches Glinda and Elphaba, respectively. The two-part movie is a cinematic adaptation of the famed Broadway musical, which is a prequel to “The Wizard of Oz” and tells an alternate version of events in Oz before Dorothy’s arrival.
    Chu may not have been able to physically attend the premiere but his presence was felt.

    According to footage from inside the theater posted online, a video of Chu speaking from the hospital was played before the movie began.

    “I’ve waited for three years to have this moment to share a movie with you but I’ve waited my whole life to have this moment, to have a fifth child right now,” he said in the video, as the audience was heard collectively “aww-ing” at the sentiment.

    With a laugh, Chu added that “of course, this little girl knows when to show up.”

    Jonathan Bailey, Bowen Yang, Ethan Slater, Michelle Yeoh and Jeff Goldblum round out the ensemble cast.

    Part one of “Wicked” will soar in theaters on November 22. The second film is expected in November 2025.

    LSU criticized after bringing caged live tiger into stadium before defeat to Alabama
    kraken6gf6o4rxewycqwjgfchzgxyfeoj5xafqbfm4vgvyaig2vmxvyd.onion
    No. 15 LSU has been criticized for unveiling a live caged tiger in its stadium for the first time in almost a decade before they were routed 42-13 by No. 11 Alabama in their SEC showdown.

    Ahead of “The First Saturday in November,” a live tiger named Omar Bradley, owned by Florida resident Mitchel Kalmanson, was brought out in an enclosed cage with a black curtain over it, before the stadium lights went dark and a spotlight flashed onto the cage as it was unveiled.
    https://kraken2krnqodidvlh4aa337cpzfrhdlfldhve5nf7njhumwr7instad.com
    kraken в тор браузере
    The tiger laid down and then paced around his cage, which was attached to a truck, while photographers crowded around it, still keeping their distance. After a few minutes, the cage was slowly driven off the field at Tiger Stadium in Baton Rouge, Louisiana.

    LSU has a long tradition of bringing caged tigers into the stadium on gamedays but, since 2015, the school has moved away from this and instead keeps its current live tiger mascot named Mike VII in a 15,000-square-foot enclosure on campus.
    But Louisiana Gov. Jeff Landry pushed for the return of this tradition, much to the frustration of the LSU community, which circulated several petitions against the practice which gathered more than 27,000 signatures between them by Sunday morning.

    Footage posted on social media also showed protesters outside the stadium holding placards with slogans including, “Justice for Omar” and “Did Tiger King teach us nothin’.”

    For Landry, having a live tiger on the field was all about “tradition,” he told FOX News on Friday.

    “This is about from Mike One through Six, we have had a live mascot on the field like many other colleges have before,” he said.
