Wednesday March 8 marks International Women's Day, with festivals, concerts and exhibitions among the numerous events planned around the world to celebrate the achievements of women in society. The annual event has been held since the early 1900s and traditionally promotes a different theme each year, with this year's edition calling on people to #BeBoldForChange and push for a more gender-inclusive working world. Reuters photographers have been speaking with women in a range of professions around the world about their experiences of gender inequality.

“Wells Cathedral is a Church of England cathedral in Wells, Somerset, England. Built between 1175 and 1490, Wells Cathedral has been described as “the most poetic of the English Cathedrals”. The Wells clock, an astronomical clock, is located in the north transept. The surviving mechanism, dated to between 1386 and 1392, was replaced in the 19th century, and was eventually moved to the Science Museum in London, where it continues to operate. It is the second-oldest surviving clock in England”. – Wikipedia

“The Great Barrier Reef is one of the most important sea turtle habitats in the world, with Lady Elliot Island being a key part of that habitat. Every year between November and March the green and loggerhead turtles lumber up the same beach on which they were born more than 50 years ago. These turtles nest on Lady Elliot Island up to nine times in a season, laying between 80 and 120 eggs per clutch. About eight weeks later, young hatchlings leave their nests and head towards the ocean (January to April)”. – Wikipedia

The truth can never be seen right away. Only by looking from a certain angle can we view the true nature of things. At other times, only with the help of some special object can we discern order in chaos. Anamorphosis is a form of art that allows us to see an object only by viewing it from a certain angle or by using cylindrical or conical mirror. Unsurprisingly, the first person in history to ever use this type of technique was the Leonardo Da Vinci. During late Renaissance period this technique was popularized as a children’s toy. Now, however, few people use this form of imagery due to its intricacy. Istvan Orosz, born in 1951, is one of the few people who specialize in anamorphosis. In our opinion, his most stunning piece of art is the one where a shipwreck scene turns into a portrait when viewed through a cylindrical mirror. (Photo by Jonty Hurwitz)

Have you ever been interested in the sign language? Surely you’ve always wanted to learn the art of sending a message using just your hands. To help people achieve this goal, Alex Solis has taken a photo of a hand showing each letter of the alphabet. However, this has been done many times before, which is why Alex decided to make each of the photos more interesting by placing little drawn animals and creatures onto each photo. Thanks to these cute little drawings the pictures become very endearing and memorable. All the little creatures blend in seamlessly into the pictures thanks to their well-chosen poses. This project, created by Alex Solis, is very unique and useful, allowing anyone to quickly remember all the listed hand gestures. (Photo by Alex Solis)

“Hippo Chase”. As we approached the camp the Selinda Reserve of northern Botswana our boat passed by a hippo resting in the water. I turned around to look back at the boat's wake and saw the hippo charging after us! The hippo must've been tired from an all-nighter because he was angry. He rose way up out of the water three times trying to chase our boat! He was coming at us with such force that he created a wake of his own. Photo location: Selinda Reserve of northern Botswana.

Prices of crude oil and most other commodities rebounded in Asia on August 25 but stayed under pressure following a global sell-off sparked by the faltering economy in China, the world's top user of industrial metals and energy. Gold prices remained steady, boosted by prospects of increased demand due to its status as a safe haven in times of turmoil. (Photo by Manan Vatsyayana/AFP Photo)
