I’ve always been intrigued by the markings of giraffes–how they vary between individuals and how they look like pieces of a puzzle, cracked mud or even tectonic plates in my scientific mind. I’ve tried many times to capture them but it was never right. Here, this oxpecker in a tight crop, lost on the abstract surface and framed by the legs of the larger animal finally seems to work.

Setting sun lights up clouds over Salar de Atacama in north Chile. I took this photo in July 2011 and at that time clouds like this were worrying sign of more unusual snow fall which already blocked roads to Bolivia and Argentina. Thankfully this time it just served as spectacular canvas to a sunset and reminder how beautiful is the world we live in. Salar de Atacama, Chile. Photo/caption credit: Magdalena Rakita

Walking down a main street in Addis, I met this young character. We started talking and soon became friends. One day, he invited me to his home to try some famous Ethiopian coffee, prepared traditionally. As I drank cup after cup of exquisite, freshly roasted coffee, this scene emerged in front of me. In a way it described my experience of Ethiopia, and other African nations I had worked in: a rapidly changing, dynamic world where tradition and modernity struggle to coexist. Addis Ababa, Ethiopia.

Winter is extremely beautiful in Lithuania. It was an early morning and minus 25 degrees Celsius outside. This landscape feels out of this world, but in fact it’s in the outskirts of my home city, Kaunas—just a mile away from my house. Oftentimes beauty lies just a step away from our door.
