In 2013 a bunch of "scruffy skateboarders" challenged the might of the cultural elite of London. At first, few took much notice, but over the next 18 months, the skateboarders unleashed the power of local support with dramatic effect.

For nearly 200 years, Elmina Castle was one of the most prominent staging posts of the transatlantic slave trade. Today it stands as a reminder of humanity's inhumanity of the past. Or does it?

Despite being one of the most essential minerals on our planet, vital for maintaining human life, how many of us have ever considered where the salt we use every day comes from?

Mustafa is one of the poorest people I have ever met; he is always one of the most generous. His simple act of kindness led me to question what generosity actually means.

Believe it or not, I came very close to leaving Toronto without photographing Niagara Falls. The weather forecast was for heavy rain, and I would need to go at a crazy hour to reach the falls in time for sunrise. But a break in the storm allowed me to experience a moment which will stay with me forever.

Ours is a complicated world, so much so that sometimes we see complication even where it doesn't exist. But it was a chance encounter with a fisherman in Madagascar which left me wondering what solutions might be hiding in plain sight if we open our eyes to them.

This photograph, captured in 2013, will always be special to me. It was the first of my photographs to receive a thousand likes on social media, but more than that, it taught me how powerful a photograph could be.

How many stories could the crumbling walls of the old prison in Port Louis tell? Few would be surprised if they were stories of regret and despair for misdeeds which led to incarceration. More curious is the relief some prisoners must have felt as they entered the prison for the first time. Theirs are the largely untold stories of the willing prisoners who chose prison as an escape from the hardships of the plantations.

Money and sport have always been uncomfortable teammates, but in the end, it has always felt like sport came first. But this World Cup feels different. Does the 2022 World Cup mark the moment when money takes the lead and sport is left to follow after?

Do you remember photographs? I mean real photographs — the kind you hold in your hand, not view on your phone. For those who are too young to remember (or those of you who are old enough but want to enjoy a walk down memory lane), let me share with you what is was like to capture moments on film rather than on a sensor.

At the age of 16, Janet Devlin became an overnight star. By the age of 20, she was an alcoholic. To her adoring fans, the singer from Northern Ireland had the world at her feet, but away from the public eye, her mental health was spiralling out of control.

If what we read on the Internet is to be believed (and who doesn't believe everything they read on the Internet?), photography is dying before our eyes. But is it, or are we simply entering a new phase of the creative age?

Despite the pain of leaving her children behind in Madagascar, Janine was full of hope for the future when she travelled overseas to begin a new career in the restaurant industry. Instead, she discovered she had been trafficked into a brutal world of prostitution and sexual violence.

With flash floods, freak storms, and record-breaking heat waves every year, is it time to recognise that climate change is real and we all have to play our part in reducing our impact on the earth? Scott Poynton of The Pond Foundation certainly thinks so.

Exhausted from days of sleep and oxygen deprivation, I stood staring up at the summit of Kilimanjaro and wondered, for the first time, whether this would finally be a challenge too far.

In the four years that it ruled over Cambodia, the Khmer Rouge was responsible for the deaths of an estimated two million people. Mass graves were still being discovered years after the fall of the regime, such was their disregard for humanity. To date, over 20,000 burial sites have been identified; the United Nations have declared these as the sites of multiple crimes against humanity. The people of Cambodia simply call them the Killing Fields.

The two children circled cautiously for a few moments, each unsure of the other, until suddenly, the smaller of the two punched the taller boy straight in the face and didn't stop punching until the job was done. Thai Boxing is not for the faint-hearted. But the real fight is not being fought on the mats; there is a far more significant challenge that all sports must soon face.

Look at this photograph; what do you see? On the surface, it is a story of everyday poverty in the 21st century but, as I have learned, there is always more to every story if we are prepared to look deeper into the narrative.

I have always been drawn to the eyes of the people I meet. As a window to the soul, our eyes show truth no matter what face we choose to display to the world. And so it was with this mother I met in a quiet fishing village on the outskirts of Mumbai.

As a photographer, I have always aspired to create photographs that have never been seen before: unique and spontaneous moments. But capturing certain photographs have become almost a rite of passage for any travelling photographer – even if they have been photographed thousands of times. This one is mine.
