Under Exposed: Pekka Tuuri (Finland) – Great white shark, Isla Guadalupe, Mexico. “Isla Guadalupe is the world capital when it comes to observing great white sharks, but cage diving seriously limits the possibilities to take ‘fresh’ pictures. When I took this, the water close to the surface was quite milky, making photography very challenging. From out of the “mist”, I saw this great white shark lurking behind a school of fusiliers. I quickly focused on the shark and set a wide aperture to get focus blur on the fish, along with a fast shutter to avoid excessive motion blur”.

X Factor and Celebrity Big Brother starlet Chloe Khan is seen working up a sweat at her luxury home on August 30, 2016. The CBB star squeezed into a pair of super-tight leggings and a teeny crop top for a very public workout. She may be a self-made millionaire, but life wasn't always so good for Chloe Khan. The Celebrity Big Brother star, 25, has revealed she was brought up in poverty as a child in Wakefield, West Yorkshire, UK. Chloe lived with her mother on a council estate before she auditioned for the X Factor and became a playboy model. (Photo by Palace Lee)

Runner-up. “The heavens opened and the streets around Shibuya, Tokyo, were suddenly drenched in even more colour and movement. I was taking photos (my friend was holding the umbrella) when I noticed this woman at the crossing. I’m pleased with the futuristic feel of the image”. (Photo by Katherine Bridgestock/The Guardian)

Sleep under the Stars, hosted by Hepburn Wind, has given us an opportunity to enrich our daily life with art. Thanks to this festival, a regular wind turbine was turned into a marvelous peace of art. The artwork is especially noticeable, since its theme greatly contrasts with the background behind the wind turbine. Moreover, the idea of drawing a woman-giantess walking over the mountain tops on a large conical object is quite extraordinary. Nevertheless, the grey and green colors of the picture were very well chosen for this particular image. You can only imagine the obstacles that the artists had to face when making a picture on such a large object. However, nowadays, people never cease to amaze with their ingenuity, leaving us gaping in awe at their creations.

Peasants in the re-taken Somme District work in the fields, circa 1916- 1917, in this Library of Congress handout photo. For women 100 years ago, opportunities to work beyond the home and take part in political life were very limited. As the 20th century progressed, hard-won progress included gradually improved voting rights, while the upheaval of war pushed doors ajar as women worked as part of the war effort. U.S. Library of Congress archive photos show women's workplaces ranging from a flour mill in England to a coal mine in Belgium or Lincoln Motor Co.'s welding department in Detroit. International Women's Day is celebrated on March 8. (Photo by Reuters/Bain Collection/Library of Congress)

“Michael Jackson, the performer, consistently transcended racial and gender perceptions; Michael Jackson tribute artists, impersonators and lookalikes reflect this in that they embody a wide span of inspiration and intention. The current crop of impersonators are people who take great care in their appearance – some spend a lot of money and time on their make up and clothing, while others are more concerned with the physical gestures associated with his dances while expressing very little concern in the creation of an illusion”. – Lorena Turner.

Modern art is truly fascinating. Not in a way that it produces some novel things that will fascinate future generations for decades and even centuries to come. No, that is very far from the truth. On the contrary, modern art is essentially anything (yes, any little thing) that is a bit unusual and was created by a famous person. Let’s take the creation of Antoine Bridier-Nahmias for example. His brainchild is a set of pictures of petri dishes that were contaminated by various cultures of fungi. If this is art, I missed my chance of becoming famous when I accidentally left a piece of bread in a bag in a cupboard for about six months, and didn’t take a picture of the rather shocking results that awaited me when I finally discovered it.
