The photo was taken with a 50mm prime, uncropped, so we were actually very close to each other when I took the picture.

The process of getting a photo can be a lot of fun. I have a piece of pineapple as the "bait", he was unsure at first but no doubt realize my existence. Usually you use a long lens so that you can get a pic without him noticing. But there is another way, a time-consuming, ass-soaring way: long time presence. If you stay in the same spot holding a camera for like 5 min, he will understand that camera is not a gun, and you are just a lazy ape (which is true). Pretty much the way to take photo for children: you stay among them, in the first 3 mins, they are interested in your camera, line up to put their finger prints on your canon red ring lens, then they get used to it and leave you alone and play naturally and you can start doing your work. The establishment of a relation is one of the most rewarding part of photography. As a bonus, they may grow interest in you and will actually look at the camera showing some funny looks!
