This stirring collection of photos which offer a glimpse behind the scenes of army life have all been selected as winners in an annual competition. The remarkable pictures in the Army Photographic Competition show Britain's soldiers at work and play. They have been taken by amateur and professional soldier cameramen and include images from operations in Afghanistan, air shows and sporting events. The winners were announced at a ceremony held at the Army Headquarters in Andover in Hampshire. (Photo by Jamie Peters/MoD/Geoff Robinson Photography/REX Features)

“Tilt-shift photography” refers to the use of camera movements on small- and medium-format cameras, and sometimes specifically refers to the use of tilt for selective focus, often for simulating a miniature scene. Sometimes the term is used when the shallow depth of field is simulated with digital post processing; the name may derive from the tilt-shift lens normally required when the effect is produced optically.

This latest photo series by Anelia Loubser, a photographer in Cape Town, reminds us that even the simplest change in perspective can change how things look drastically. By selectively cropping and flipping the dark portraits in her “Alienation” series, Loubser makes basic human portraits look like creepy alien close-ups.

Former Soviet President Mikhail Gorbachev as he bids the last farewell to his wife Raisa Gorbacheva during the funeral ceremony in Moscow, Russia, 23 September 1999 (reissued 30 August 2022). According to a Moscow Central Clinical Hospital statement, former Soviet president Mikhail Gorbachev has died at the age of 91. As a supporter of the de-Stalinization programs of his predecessor Nikita Khrushchev, Gorbachev initiated numerous reforms during his tenure. He signed a nuclear arms treaty with the United States and withdrew the Soviet Union from the Soviet-Afghan war. His policies created freedom of speech and press, and decentralized fiscal policy planning and execution to increase efficiency. Gorbachev was the last leader of the Soviet Union, overseeing Russia’s transition from one party rule to fragile democracy. (Photo by Sergey Chirikov/EPA/EFE)

Edinburgh-based physicist-turned-web-designer Tom Beddard was inspired by geometry to create these virtual Fabergé fractals – made up of self-repeating patterns, so that structures within the object resemble the whole. “Within a 3D fractal, there is infinite detail”, says Beddard, 37. “The closer you zoom in, the more structure is revealed”. Beddard rendered the fractals using WebGL, a technology used to animate 3D scenes in a browser.
