It is already one of the world’s most iconic cities, but this incredible collection shows how much Paris has changed over the course of the past century. The collection, by French photographer Julien Knez, shows Paris in the 1940s against a backdrop of how the same places look today. Knez says he put the striking collection together to celebrate the 71st anniversary of the city’s liberation from Nazi control in August 1944. Here: Soldiers outside the Hotel De Ville in the 1940s.

“LSD Photo Advertising Studio is comprised of Marco and Paolo. They are photographers who compose, shoot and post-produce all of their images together. For over ten years, they have been creating images from start to finish. Marco and Paolo have different backgrounds of experience: Paolo started as an illustrator then a photographer, and now he’s at Marco’s side and in his head throughout shooting. In turn, Paolo does all the post-production with Marco in his head and at his side. Marco has always worked as photographer”. – Tim Mitchell

“I started photography in June 2009. At the time, I was searching for a way to express both the rigorous scientist and the creative artist in me. There are few hobbies that let these two approaches work together, so I really was enthusiastic about it: I am now spending all my free time studying various techniques, contemplating others' fantastic work, and of course, making pictures”. – Christophe Kiciak.

Golden-crowned Kinglets boldly bear their flashy lemon-yellow crest and a black eyebrow stripe. Taking a good look at them might be rather challenging, since they spend most of their time in the dense fir foliage or spruce. However, if you’re patient enough to find them, listen for their shrill, thin song. Though these “little Kings” are only a tad bit larger than a hummingbird, they can survive easily extreme cold by huddling close together. They breed in montane west and the far north and only visit North America during winter.

In June, Mallory Gaudet picked up a little ginger kitten on the street and took him home. Mallory worried that the baby will not be able to get along with her ​​two other pets – ferrets, and they will hurt him. But it turned out that the new member of the family, named Ned, could get used to this neighborhood very fast. Moreover – these three animals became really best friends. Now kitten and ferrets play, eat and sleep all together. But the most touching thing is when Ned “washes” the ferrets. Interspecific and intergeneric animals’ friendship – is a rare phenomenon. But ginger kitten and two of his fellows break all the stereotypes.
