This set was taken ten years since my first extensive travels through the Samburu, Turkana, Rendille and Pokot communities of northern Kenya. That trip was a formative experience for me: as well as meeting my long term guide and friend Mohammed, I had come to know and love these communities and the environment that shaped their way of life. Following many years of drought, weather events on this trip sadly proved equally extreme, including floods, landslides and loss of life. Yet somehow, the tribal groups celebrated at Lake Turkana as this year of opposites came to a close.

Having spent many months street photographing across India and Bangladesh in 2005, I was already familiar with this country of incredible human and physical diversity. For this journey in 2014 I sought out the 'Adivasis' - or tribal groups - of the world's second most populous nation. I also spent time photographing the holy men of the subcontinent. The trip was hugely eventful, and whilst it had some disaapointments I left India with my eyes further opened by its inspirational people and lands.

The far south of Angola: crazy bureaucracy but the reward of encounters with wonderful traditional cultures that are really infrequently visited by outsiders. Beautiful interactions with the Mumuhuila and Muhacaona: some of which you see here. On my way home I detoured with three weeks in the Omo Valley to visit old friends and, for the first time, photograph the Arbore and Dassanech. Wonderful memories again.

The far North of Kenya in 2011: two years had passed since my first trip to this baking hot semi-desert and further drought threatened Samburu, Rendille and Turkana villages in the region. During this project I wanted to really understand more on how climate changes are undermining traditional pastoral ways of life in East Africa. Why did I shoot these outside, not inside the darkness of huts?Simple: I was also shooting with a big camera (10x8 inch film) as well as my digital and it needed a LOT of light. Two setups weren't possible. Click on any picture to enlarge

Ethiopia can justifiably claim to be one of the most diverse countries on earth, both in terms of its geography and its cultural anthropology. I have a profound love for this country: I probably know it better than any other in Africa. During this project I travelled from the baking Afar lowlands in the far east of the country to the humid forests of the far west, where groups including the Nuer from neighbouring Sudan have settled. Part II of my Omo Valley project is also found here. Click on any picture to enlarge

Taken on my second trip to Ethiopia's Lower Omo Valley in late 2009. This increasingly visited location is not without its challenges: resource development and tourism are two more prominent ones. The area is very well known for its concentration of diverse traditional cultures including the Hamer, Nyangatom, Karo, Mursi and Banna; sometimes cultural tourism and the traditional way of life collide in not so desirable ways.

The Himba socieities living in Namibia's arid, rugged Kaokoland region are visually unique. Himba women combine ochre and buttermilk to incredible effect: the skin glows with a metallic red sheen that sits over an earthy brown base. What results is a colour and effect rarely ever seen elsewhere, perhaps with the exception of small parts of Hamer women (i.e. the neck and hair) living in the Omo Valley in Ethiopia. The combination of colour and reflectivity of light on female Himba skin is an incredibly powerful vision, and my aim was to capture some of the these effects through this series.

Twenty images from remote societies in the far north of Kenya, including the Samburu, Rendille, Turkana and Pokot.This project involved 6 weeks hitching through Kenya's arid and remote north; an experience not without it's complications as guns are deeply embedded into the fabric of day to day life. The nomadic and semi-nomadic groups featured in this series, in some cases engaged in armed conflict with each other, share a similar beauty and vibrancy in their appearance to those of Ethiopia's Omo Valley, just to the north.Click on any picture to enlarge

Black and white portraits from some of West Africa's most remote societies, including the Wodaabe and Fula in Niger, the Tuareg in Mali, the Tamberma in Togo and the Betammaribe in Benin, who practice a uniquely intricate form of facial scarification.I spent two months travelling through the arid Sahel on the southernmost fringes of the Sahara. An area of little development interest provides the backdrop to the unique cultures of West Africa's most remote groups. Most of the societies were almost entirely removed from developed lifestyles amp; the people that I encountered had an appearance that appeared little changed from past generations.

My first serious experiment with colour portraiture in Ethiopia's Lower Omo Valley, taken in late 2009. As always, my focus were striking individuals from the Hamer, Nyangatom, Karo, Mursi and Banna communities. The Lower Omo Valley certainly receives the most attention from outsiders in this triangle of human diversity where Kenya, Sudan, and Ethiopia meeet, and it is obvious why: the colours that adorn individuals from these groups are striking. And when viewed away from the powerful, bleaching African sunlight, they take on an almost luminous effect. Click on any picture to enlarge

Images from my first trip to Africa in 2006 where I travelled across parts of Southern and Eastern Africa.Along the way I had the opportunity to spend time with many of Africa's most iconic societies, including the Bushmen and Himba of Namibia, the Maasai of Kenya and the groups of Southern Omo in Ethiopia.Click on any picture to enlarge

Pictures taken across Africa and Asia on journeys through deserts and savannah. This is amongst my earliest work, and predates much of my portraiture. Featured are some beautiful wildlife scenes from Namibia's Etosha National Park, and strange mist shrouded scenes in the Namib DesertClick on any picture to enlarge

These images were taken with a 10x8 Large Format camera during my second trip to the far North of Kenya in 2011. Shooting with this camera is a tremendous experience and to me it naturally lends itself to environmental portraits. You really should see these images as 2m wide prints, but you get an idea here.... This work was displayed in September 2011 in my London show. Click on any picture to enlarge
