Scottish photographer George Logan and retoucher Tony Swinney let’s you imagine what it would be like if your cat wasn’t just a purring ball of fur. As a part of “Big Cat, Small Cat” ad campaign for Whiskas, they created a series of funny images showing tiny domestic cats chasing after antelopes, zebras, elephants and doing other “big cat” stuff.

The time of selfies with duck faces is long gone and ridiculed, though some persist in doing it. Helene Meldahl, however, didn’t want to give up the trend, but had to think of a creative way to keep doing it. So she decided to create comical pictures by drawing over the selfies that she has made. Some people just can’t stop taking pictures of themselves. It makes you wonder, what they would do in an era before the existence of cameras… Oh, poor souls, they would definitely suffer greatly without the possibility of sharing on instagram their “stunning looks” and the pictures of food that they eat every 2 seconds.

A landscape photographer turned the camera on himself to take a set of incredible selfie while visiting some of the world's most beautiful destinations. Paul Zizka, 39, from Alberta, Canada, has been a photographer for nine years, and thought that featuring in his own pictures would emphasize the nature surrounding him and create a more unique shot. Here: Lake Minnewanka, Banff National Park, Alberta, Canada. (Photo by Paul Zizka/Caters News Agency)
