Mok was on the roof of the George IV Gateway of Windsor Castle when the newly married Prince Harry and Meghan Markle passed directly beneath him.

"I had less than a one-second window to take that particular shot — whilst having to focus through a metal grill I was standing over — so was happy to get anything really!" Mok wrote on Twitter.

Reuters photographer Mohamed Al Hwaity snapped the perfect shot of Saudi men performing a stunt known as "sidewall skiing" (driving on two wheels) in Tabuk, Saudi Arabia, in 2018. The man's selfie probably turned out pretty well, too.

Amzan was competing in the Gold Coast 2018 Commonwealth Games in Queensland, Australia, in 2018.

Del Pozo said covering an event as large as the Olympics makes it more difficult to take shots that will stand out. With this photo, he knew he got something good.

"It is one of those frames that I knew when I shot it, something strange had happened, something special," said Del Pozo. "Covering an event where there are so many good photographers shooting from all angles means you need a little luck to get something different."

Reuters photographer Yannis Behrakis focused on combining the right angle, moment, and background for this shot:

"I was interested to see the faces of the contestants while diving. This task turned out to be a very difficult one as I had to focus my long lens on thin air. I shot dozens of pictures hoping to freeze the action, have it in focus and also capture an interesting moment. I got lucky with one of the top athletes of the event — Chinese silver medalist Hu Jia."

On a three-day campaign bus tour during the 2012 presidential race, Obama spoke at Bayliss Park in Council Bluffs, Iowa. AP photographer Carolyn Kaster captured this photo of Obama at the perfect angle to make it look like he was grasping a ball of light.

When Jacob, the young son of a White House staffer, entered the Oval Office in 2009, he told then-President Obama that "My friends tell me that my hair is just like yours." Obama decided to let Jacob see for himself.

"And at that moment President Obama bent over and Jacob touched his head. The president said, 'Go ahead and touch it.' And I snapped that one picture," photographer Pete Souza told NPR. "I have one picture of this brief moment, and it kind of took on somewhat of an iconic status in years to follow."

Photographer Jonathan Bachman was in Baton Rouge covering the first protest of his career when he captured what many see as the defining image of Black Lives Matter rallies across America.

"She had no facial expression at all. She just stood there," Bachman told Reuters of the woman pictured being arrested. "I knew it was a good frame and it was something that would tell a story. When I came back to my car and I looked at that picture, I knew it would speak volumes about what was going on in that moment right there and over the past few days in Baton Rouge."

The name comes from Stonehenge, stone sculptures in the Salisbury Plain of England in which the sun lines up perfectly during the summer solstice.

Reuters photographer Eduardo Munoz was in Times Square for Manhattanhenge 2019, and took this snapshot of the sun setting inside the city's grid.

A solar eclipse is when the moon crosses between the Earth and the sun and blocks out the sun's light.

The total solar eclipse on August 21, 2017 was the first time in 99 years that a solar eclipse crossed the US from coast to coast. It lasted just an hour and 33 minutes, beginning in Oregon and ending in South Carolina. That left photographers in the path of totality with mere minutes to capture the moon blocking the sun's light completely.

Rick Wilking managed to photograph both the total eclipse and a passing jet in Guernsey, Wyoming.

The crowds filling the streets of Bunol, Spain, for the annual La Tomatina festival are hungry for tomatoes. Not to eat them, but to toss them at each other in an epic food fight that takes a squad of fire trucks to clean up.

This past year, around 22,000 people gathered in the town square to throw tomatoes at each other. The photos are pretty epic, but this one captured the moment an enormous bucket of tomatoes completely covered festival-goers.

The photo was taken by Toby Melville in 2016 at a service for Queen Elizabeth's 90th birthday. The checkered floor in St Paul's Cathedral made for an amusing photo when the Queen walked diagonally across its black squares the way a queen moves in chess.

An ad on the back of a camper van appears to show the same mountains and trees as the actual surroundings.

They are, in fact, two different places, but they look incredibly similar. The image on the van is of Moraine Lake, and the location of the photo is Icefields Parkway (both in Canada), according to Reddit user tomboski who posted the photo. They also posted a few failed attempts to capture the matching scenery in order to prove that the photo is authentic when some claimed it was Photoshopped.

These tourists at an elephant sanctuary were helping an elephant cool off by splashing water on it. Little did they know that the splash took the shape of the elephant's head.

Reddit user RailTieYardGame posted the photo, which went viral.

Photographer Kai Pfaffenbach explained how he got the incredible shot.

"When Usain Bolt prepared for his 100m semi-final I decided to play with slow shutter speed for that race," he told Reuters. "I set my camera (shutter speed) to a 50th of a second and was waiting for the moment when he passed my position. At the very right moment he looked to his left with the proud smile and my first thought was: 'hopefully I got this sharp.' Well, I've been a lucky bunny in this case but I still would not have imagined at this moment that this picture would go viral and get worldwide recognition."

This photo of the moon creating a sixth ring in the Olympic logo went viral during the 2012 Olympic Games in London, garnering thousands of retweets. Many also joked about the International Olympic Committee's strict policies about protecting the Olympic logo.

"Moon taken to court by IOC for violating Olympic brand ban," Twitter user Jon Holmes wrote.

The moon's orbit around the Earth isn't a perfect circle — it's an ellipse, which means its distance from the Earth varies. A supermoon happens once or twice a year when the moon's orbit brings it closest to the Earth.

Photographing a supermoon properly can take years of planning, and on December 14, 2016, Reuters photographer Christian Hartmann angled his shot perfectly to show a statue atop the Notre-Dame in Paris appearing to touch the large, looming orb.

Hussein's photo of the couple smiling together in a dramatically lit rainstorm quickly became an iconic symbol of their new chapter.

"It was pouring down with rain, which can be very tricky when shooting flash photography and also meant Harry and Meghan would be under an umbrella, which usually means it's hard to get clean photos of the couple," Hussein shared a statement with British GQ magazine. "Little did I know these elements would come together so spectacularly to produce a timeless image of the couple."
