The shoemaker in Turkey, the potato seller in Vietnam, and the weaver in Bolivia are among the billions of low-income entrepreneurs who make the world go round. They are also the type of people who can benefit significantly from microfinance. Every year, the Consultative Group To Assist The Poor (or CGAP) hosts a photo contest asking entrants to submit photos based around the idea of microfinance.The purpose of the contest is to give amateur and professional photographers a chance to show the different ways that poor households manage their financial lives and make their lives better through financial inclusion.

“Hippo Chase”. As we approached the camp the Selinda Reserve of northern Botswana our boat passed by a hippo resting in the water. I turned around to look back at the boat's wake and saw the hippo charging after us! The hippo must've been tired from an all-nighter because he was angry. He rose way up out of the water three times trying to chase our boat! He was coming at us with such force that he created a wake of his own. Photo location: Selinda Reserve of northern Botswana.

“Double head vulture”. On the day of windy days during raptors migration some people in my country start to catch these tired raptors, so in this day we go to photograph some raptors and we saw these tow tired vultures, so we start to drag them away from the hunters until they reach a good hidden place, to make them safe until they start a new journey. Photo location: Kuwait. (Photo and caption by Mohd Khorshed/National Geographic Photo Contest)

“Microscope images forge an extraordinary bond between science and art, said Hidenao Tsuchiya, Olympus America's Vice President and General Manager for the Scientific Equipment Group. We founded this competition to focus on the fascinating stories coming out of today's life science research laboratories. The thousands of images that people have shared with the competition over the years reflect some of the most exciting work going on in research today – work that can help shed light on the living universe and ultimately save lives. We look at BioScapes and these beautiful images as sources of education and inspiration to us and the world”. – OlympusBioScapes
