The human eye is very complex; the human brain very advanced in terms of its ability to process light and imagery. This results in us seeing a world that is visually busy. But, what the camera has the power to do, through silhouette photography, is to simply declutter our world. By leaving only the outline of the subject our focus shifts to the animal itself and it is there that the human eye can find rest. This Dusk to Dawn gallery featured on the BBC News home page.
Elephant Sunrise - In the blue smoke, the result of underground fires, an elephant sniffs the dawn, in Botswana's Okavango Delta. Photographing through the bushes, I offer you a glimpse into one of Africa's last great wildernesses.
A Zebra and Seven Oxpeckers - I was racing back to camp in Kenya's Masai Mara, when the sunset burst into life. Searching for a subject, it was only later that I noticed the seven oxpeckers enjoying the ride on the zebra's back.
Giraffe Sunset - A giraffe and her baby walk over a rise, into the setting sun, in Kenya's Masai Mara.
The Crossing - A lone bull elephant crosses the mighty Zambezi River at dusk, pausing momentarily with an egret on his back, allowing me to capture this tranquil scene (Mana Pools, Zimbabwe).
Zebra Sunset - In Kenya's Masai Mara, the sun sets with a bright and vivid intensity. A trio of zebra walk across my frame as Africa once again steals my heart.
Hippo Bubbles - Lying on the bank of the Great Ruaha River in Tanzania, I wait for a hippo to surface in my frame of bubbles. I also hope no crocodile is placing me in a frame of its own.
Bat Blizzard - The largest migration in the world is of bats, each with a wingspan of over one metre. Here you see them blocking out the rising sun as they return from a night's foraging in the Congo.
Elephant and Calf - In Kenya's Masai Mara an elephant mother and her calf graze peacefully off into the sunset.
Elephant Reflecting - A bull elephant pauses for a moment of contemplation, standing in Zambezi Riverof Zimbabwe's Mana Pools.
Elephant on Fire - In Kenya's Amboseli National Park an elephant drinks quietly at a waterhole, grass fires rage and the sun sets in the background.
