Kisilidjan Diatomite Plant, Iceland
Autumn pines litter a barren lava field which surrounds the chimneys of this industrial plant near the northern shores of Lake Mývatn.

Hverarönd, Iceland
This volcanic area of boiling pools, silvery mud and steaming fumeroles looks like a different planet. It felt like one too thanks to the freezing gale force arctic conditions prevailing that day - the 4x4's heated seats were never more welcome!

Wadi Rum, Jordan
With formations resembling dripping chocolate, you could almost believe the desert rocks of the Wadi Rum are molten, so fierce are the temperatures in its harsh but beautiful landscape.

Selfoss, Iceland

Gower, Wales
An unusual view of the Worm's Head; here at high tide it looks like an island, but as the sea level drops a causeway appears linking the rocky promontory to the Rhossili headland, enabling intrepid walkers to reach it. The orange sky reflected on the wet foreground rocks lends the image an other-worldly atmosphere.

Mountains of Madeira
Pre-dawn, this 20-second exposure captured the delicate first rays of refracted red light on this primeval volcanic landscape, drawing out the creeping cloud into fingers which reach ominously into the valley behind. The impression of this image is one of smothering by a white blanket; however while the long exposure has created intricate details in places, the blanket of cloud is too large and largely devoid of detail, so I think the image although eye-catching is not overly successful.
