“The knight and his steed”. This picture was taken in a natural but controlled environment. There are pictures that can not be done in nature or that would imply a very high cost of both time and money, thats why photography workshops are run conducted at strategic locations and bringing EVERYONE who is interested, the basic notions (lighting, camera handling, composition, etc...) or the specimens, and afford them the opportunity to take pictures like this. Although controlled, this shot was not prepared at all, I was performing a workshop with the agalychnis callidryas treefrog from Costa Rica when the frog managed to jump to the branch where this huge titan was sleeping... I had my gear ready so I only had to change a few settings and shoot... the rest is history. (Photo and caption by Nicolas Reusens Boden (Sweden)/2014 Sony World Photography Awards)

“Horst Ludwig Wessel (October 9, 1907 – February 23, 1930) was a German Nazi activist who was made a posthumous hero of the Nazi movement following his violent death in 1930. He was the author of the lyrics to the song “Die Fahne hoch” (“The Flag On High”), usually known as Horst-Wessel-Lied (“The Horst Wessel Song”), which became the Nazi Party anthem and, de facto, Germany's co-national anthem from 1933 to 1945”. – Wikipedia
