Bild des Monats Mai - "Sonnenuntergang in Berlin"

Bild des Monats Mai - "Sonnenuntergang in Berlin"

Manchmal muss man einfach an einen bereits bekannten Spot zurückkehren, um ein völlig anderes Bild zu machen als bei einem vorherigen Besuch. Das Bild des Monats im Monat Mai ist vom gleichen Spot aus enstanden wie das Bild des Monas März, zeigt jedoch eine völlig andere Stimmung und gibt euch einen Einblick in diverse Techniken, die ich nutze, um meine Ergebnisse zu erzielen. In diesem Beitrag geht es um die Kombination zweier Aufnahmen, um eine möglichst gleichmäßige Belichtung zu erzielen, ohne dabei auf Techniken wie HDR zurückgreifen zu müssen.


Einführung

Als Landschaftsfotograf ist man inzwischen mehr oder weniger an die Nachbearbeitung gefesselt. Das meine ich überhaupt nicht negativ, im Gegenteil, es macht Spaß mit LR/PS noch das letzte aus den Bildern raus zu kitzeln. Auch wenn natürlich manche Dinge noch spontan im Workflow entstehen, sollte man die groben Schritte der Bearbeitung aber schon beim Aufnehmen des Bildes im Kopf haben. Hinterher irgendwie an den Reglnern schieben bis es passt kann zwar funktionieren, zeugt aber wenig von zielorientiertem Arbeiten. Gleichzeitig ist man als Fotograf aber immer abhängig vom Licht, d.h. man kann zwar zuhause den Spot planen, den Wetterbericht prüfen und die Ausrüstung entsprechend gestalten, aber wenn vor Ort das Licht nicht zu dem passt, was man sich vorgestellt hat, muss man flexibel sein oder es eben sein lassen.


Planung

Ich versuche in der Regel die Aufnahmen so gut es geht vorher zu planen. Gerade bei Sonnenuntergängen ist das aber äußerst schwierig, da kleinste Wolken darüber entscheiden können, ob der Himmel blutrot oder einfach graublau wird. In Berlin hat man im Frühling/Sommer leider oft das Problem, dass in Brandenburg Gewitter ist, während man in der Stadt blauen Himmel vorfindet. Als Resultat hängen am Horizont oft dicke Wolken, die in der Stadt den Sonnenuntergang ruinieren. :D Der Wetterbericht sah aber denkbar gut aus dieses mal, warm, trocken und kleinere Wölkchen am Himmel, perfekte Bedingungen für eine gelungene Aufnahme zum Sonnenuntergang. Mit TPE (hier ein Video von uns dazu) ermittelte ich den Stand der Sonne zum Zeitpunkt des Untergangs, der inzwischen deutlich weiter rechts (vom Spot aus gesehen) liegt, als noch vor 2 Monaten als dieses Bild entstanden ist (logisch, die Tage werden länger ;)).

Vor Ort

Mit 5DM3, 17-40 f4.0 L, Polfilter und 64x ND-Filter bewaffnet erreichte ich schließlich das Ziel und traf dort direkt auf Mitstreiter. Enttäuscht mussten wir leider feststellen, dass Brandenburg mal wieder zugeschlagen hatte und die gerade untergehende Sonne sich hinter einem schmalen Wolkenband befand. Aber wie hat ein gewisser Herr Jaworkskyj schon gesagt: Oft sind es die 15 Minuten NACH dem Sonnenuntergang, die entscheidend sind. Dies sollte sich auch hier bewahrheiten, nur dass es 15 Minuten gedauert hat, bis es überhaupt wieder brauchbares Licht gab. Die schon hinterm Horizont verschwundene Sonne färbte den Himmel samt Wolken wieder angenehm rot. Für die tiefer stehenden Wolken im Vordergrund reichte es nicht auf Grund des oben erwähnten Wolkenbandes.

Das Helligkeitsgefälle zwischen Himmel und Stadt war inzwischen deutlich größer geworden. Es ist nicht möglich gewesen mit einer einzelnen Belichtung den gesamten Dynamikumfang abzubilden. Natürlich wäre es möglich gewesen ein HDR vorzubereiten mit einer ganzen Belichtungsserie. Dies erschien mir aber auch wieder nicht sinnvoll, da erstens der Himmel gut aussah, wie er war, und zweitens lediglich die Stadt im Vordergrund etwas mehr Licht benötigte. Ich habe mich daher relativ spontan dafür entschieden nur 2 Aufnahmen zu machen, eine für den Himmel, eine für die Stadt und diese später durch simples Maskieren in Photoshop zu kombinieren. Der grobe Bearbeitungsplan stand zu diesem Zeitpunkt aber schon fest, so dass ichh meine Aufnahmen gezielt an meinen Plan anpassen konnte.


Die Rohaufnahmen

Die Ausrüstung viel entgegen aller Erwartungen auch sehr übersichtlich aus. Den ND-Filter habe ich aus mehreren Gründen direkt wieder eingepackt:

  1. Der rote Teil des Himmels war auf Grund der Wolkenlage ohnehin schon "schlierig" genug.
  2. Die kleinen dunklen Wolkenfetzen bieten mir in ihrer Struktur wesentlich mehr Dramatik, als graue Schleier, die nur das rot verdecken.

Auch der Polfilter blieb in der Tasche, denn:

  1. Das Licht traf fast frontal auf die Linse, die Auswirkungen des Polfilters sind dann überschaubar.
  2. Bei der Einstellung, wo er tatsächlich was am Himmel bewegt hätte, wären sämtliche Reflektionen auf dem Wasser weg gewesen. Diese sind mir aber sehr wichtig gewesen, da sie an dieser Stelle noch einmal angenehmes Licht ins Bild bringen und somit eine führende Linie zum Berliner Dom bilden.

Beide Aufnahmen sind im M-Modus entstanden. Die ISO habe ich auf 50 gestellt, Blende 8 für durchgehende Schärfe. Die Aufnahme für den Himmel ist mit 1s Verschlusszeit entstanden, die für die Stadt und die Straße mit 5s. Die perspektive erlaubte 17mm ohne große Verzerrungen, auch weil ich mich bemüht habe, den Fernsehturm nicht an den Bildrand zu quetschen, wo die Verzerrungen am größten sind.

Die Bearbeitung

Eine erste RAW-Entwicklung habe ich bereits in LR vollzogen. Insbesondere ist mir wichtig gleich am Anfang CAs zu korrigieren. Das 17-40 ist eine schöne Linse, aber man sieht oft deutliche Farbsäume und so ist auch hier der Fernsehturm nicht verschont geblieben. Später lassen sich die CAs sehr viel schlechter korrigieren, da sie durch zusätzliche Filter nicht mehr so eindeutig identifizierbar sind. Daher werden solche grundlegenden Dinge in meinem Workflow gleich am Anfang erledigt. Ansonsten wurde in der ersten Entwicklung lediglich der Kontrast optimiert über eine Kombination aus Tiefen/Lichter und Schwarz/Weiß Reglern, wie ich sie auch in diesem Video beschreibe.

Maskierung

Alle weiteren Schritte erfolgten dann in Photoshop. Das schwierigste war es eine gute Auswahl zu erzeugen, auf deren Basis dann die Layermaske entstehen konnte, um die korrekt belichtete Stadt in den korrekt belichteten Himmel zu blenden. Ich habe dabei auf die Kanäle zurückgegriffen und auf Basis des Blau-Kanals und Tonwertkorrekturen die grundlegende Auswahl gebaut, die durch etwas Verkleinern und mit weichem Rand perfektioniert wurde. Angewendet auf den Stadt-Layer ergab sich ein bereits ansehnliches Ergebnis.

NIK ColorEfex

Für etwas mehr Wärme und noch ein wenig Kontrast nutzte ich dann die Nik Color Efex, speziell Warmth/Brilliance und den Detail Extractor. Ich habe mir grundsätzlich angewöhnt den dadurch entstehenden Layer sofort auf 50% Deckkraft zu stellen, um damit den Effekt zu halbieren. Anschließend verlasse ich für mindestens 10 Minuten den Bildschirm und nur wenn ich beim Zurückkehren denke, dass es zu wenig ist, stelle ich die Deckkraft höher. Das verhindert bei mir sehr gut, dass ich es mit den Effekten übertreibe.

Farbgebung durch Verlaufsumsetzung

Für etwas mehr Lila am rechten Bildrand, der ja sowieso etwas dunkler ausfällt, nutze ich eine Verlaufsumsetzung, die mit einer Layermaske und Gradienten wirklich nur in der Ecke rechts unten angewendet wird. Der Effekt bewirkt, dass die Farbgebung auf der Straße und den hellen Gebäuden deutlich weniger grün wird, was mehr dem Gesamteindruck des Bildes entspricht.

Schärfen

Danach erfolgte eine Schärfung per Hochpassfilter. Zum Schärfen gibt es ja sehr eigene Philosophien, ich persönlich finde die Hochpassschärfung nach wie vor absolut brilliant, da sie quasi den "Maskieren"-Regler aus Lightroom automatisch beinhaltet. Wichtig auch hier wieder: Mit Bedacht vorgehen, nicht überschärfen!

Letzter Schliff

Den Abschluss bildete eine weitere RAW-Entwicklung, bei der aber lediglich Teile im Bild per Korrekturpinsel mehr betont wurden. Dies erfolgte mit einem weichen Pinsel, für den die Belichtung um eine halbe Blendenstufe erhöht wurde.

Abschluss

Wer unseren Blog regelmäßig liest, dem ist vermutlich aufgefallen, dass das Bild des Monats März aus identischer Perspektive gemacht wurde. Damals lag der Fokus aber wesentlich mehr auf fotografischen Effekten, während es dieses mal hauptsächlich um Techniken der Nachbearbeitung ging. Für kommende Beiträge aus dieser Serie werde ich aber wieder auf andere Locations zurückgreifen :)

    Narwhals may be using their tusks to play, new study finds
    лаки джет официальный сайт
    Scientists say they have the first recorded video evidence of narwhals using tusks not only to strike and manipulate fish during feeding but also engage in what appears to be playful behavior, according to the latest research.

    The narwhal, often referred to as the “unicorn of the sea” in a nod to its trademark tusk, has long remained an enigma. Scientists have observed few interactions of narwhals in their natural habitat, creating speculation about the purpose of the species’ distinctive spiraling tusk.
    https://lucky-jetts.com
    сайт lucky jet
    Found predominantly in males, the tusk grows up to 10 feet (3 meters) long — and previous research has suggested it serves as a competitive display to secure mates. But now, with the help of drones, research conducted in the Canadian High Arctic has uncovered that a narwhal may use its tusk for more than just courtship.

    In total, the researchers newly identified and described 17 distinct behaviors of narwhals involving prey. The findings revealed a wide range of interactions and dynamics between narwhals and fish as well as the extraordinary agility, precision and speed of their tusks to track moving targets, according to the study published February 27 in the journal Frontiers in Marine Science.

    “Seeing that these animals are not actually hunting the fish but exploring, manipulating and interacting with it was really a game changer,” said lead author Dr. Gregory O’Corry-Crowe, a research professor in the Harbor Branch Oceanographic Institute at Florida Atlantic University.

    Since so little is understood about this whale species, researchers like O’Corry-Crowe and his colleagues are working diligently to conduct studies to document narwhals’ unknown behaviors to better understand how these animals adapt in a rapidly shifting habitat as oceans warm and sea ice melts.
    Narwhal exploratory behavior
    The study team captured the groundbreaking footage using drones in Creswell Bay, on the eastern side of Somerset Island in Canada’s Nunavut territory, during the summer of 2022.

    As the researchers analyzed the footage, they noticed subtle nuances in the narwhals’ behavior. Footage even captured one instance of a narwhal interacting with a fish by repeatedly nudging it with its tusk — which is actually a giant tooth — without attempting to eat it.

    When researchers observed a lack of aggression in some interactions between narwhals and fish, they realized these scenarios were more similar to a cat-and-mouse game, in which the animals were chasing or “playing” rather than hunting, O’Corry-Crowe said.

    DOGE attempts to enter an agency building led to physical standoff that spilled into court
    kra28 cc
    A small federal agency that sends money to help communities in Africa became a flashpoint Thursday in the Trump administration’s efforts to shut down foreign aid and reduce the size of the federal government.

    A Trump-backed government official, staffers from the Department of Government Efficiency and federal law enforcement entered the offices of the U.S. African Development Foundation on Thursday, and the fight between the Senate-confirmed foundation’s board and Trump administration emissaries spilled into an emergency court fight, according to court records and photos of the in-person standoff captured by the New York Times.
    https://kra28c.cc

    The standoff was quelled when a judge stepped in Thursday afternoon, keeping the foundation’s existing board in place for a few days until a court hearing could take place.

    The African Development Foundation, an independent agency that has provided more than $100 million to African farmers, entrepreneurs and community organizations in the last five years, has been among the foreign aid groups that Trump has targeted to eliminate via an executive order he issued two weeks ago. The work of DOGE at the agency so far, the lawsuit says, mirrors how other foreign aid agencies have been dismantled by the Trump administration.

    Trump’s plan for the African Development Foundation snapped into action almost immediately, with DOGE staffers meeting with the foundation’s leadership within days of Trump’s February 21 executive order. The Trump administration then told a board member, Ward Brehm, he was being removed from his position, and a new acting chair would be in charge.
    Faced with the overhaul, the board held an emergency meeting on Monday to push back, according to a lawsuit filed in federal court in Washington this week. The board decided Trump’s appointee, Peter Marocco — the de-facto acting leader of USAID, another agency Trump has targeted — was not lawfully in the job, and they alerted Congress, the removed board member Ward Brehm’s lawsuit said.

    Marocco still showed up at the fund’s headquarters with staffers of the Department of Government Efficiency on Wednesday afternoon. They “were denied access to those offices,” the lawsuit said. “Marocco and his colleagues threatened to return to the offices with United States Marshals and Secret Service.”

    As the researchers analyzed the footage, they noticed subtle nuances in the narwhals’ behavior. Footage even captured one instance of a narwhal interacting with a fish by repeatedly nudging it with its tusk — which is actually a giant tooth — without attempting to eat it.

    When researchers observed a lack of aggression in some interactions between narwhals and fish, they realized these scenarios were more similar to a cat-and-mouse game, in which the animals were chasing or “playing” rather than hunting, O’Corry-Crowe said.

    DOGE attempts to enter an agency building led to physical standoff that spilled into court

    A small federal agency that sends money to help communities in Africa became a flashpoint Thursday in the Trump administration’s efforts to shut down foreign aid and reduce the size of the federal government.

    A Trump-backed government official, staffers from the Department of Government Efficiency and federal law enforcement entered the offices of the U.S. African Development Foundation on Thursday, and the fight between the Senate-confirmed foundation’s board and Trump administration emissaries spilled into an emergency court fight, according to court records and photos of the in-person standoff captured by the New York Times.

    The standoff was quelled when a judge stepped in Thursday afternoon, keeping the foundation’s existing board in place for a few days until a court hearing could take place.

    The African Development Foundation, an independent agency that has provided more than $100 million to African farmers, entrepreneurs and community organizations in the last five years, has been among the foreign aid groups that Trump has targeted to eliminate via an executive order he issued two weeks ago. The work of DOGE at the agency so far, the lawsuit says, mirrors how other foreign aid agencies have been dismantled by the Trump administration.

    Trump’s plan for the African Development Foundation snapped into action almost immediately, with DOGE staffers meeting with the foundation’s leadership within days of Trump’s February 21 executive order. The Trump administration then told a board member, Ward Brehm, he was being removed from his position, and a new acting chair would be in charge.
    Faced with the overhaul, the board held an emergency meeting on Monday to push back, according to a lawsuit filed in federal court in Washington this week. The board decided Trump’s appointee, Peter Marocco — the de-facto acting leader of USAID, another agency Trump has targeted — was not lawfully in the job, and they alerted Congress, the removed board member Ward Brehm’s lawsuit said.

    Marocco still showed up at the fund’s headquarters with staffers of the Department of Government Efficiency on Wednesday afternoon. They “were denied access to those offices,” the lawsuit said. “Marocco and his colleagues threatened to return to the offices with United States Marshals and Secret Service.”
