Shooting a lion has never come across my mind before. It seems so distant and its rare to see them in the open (usually they are behind cages!). During my trip in Africa, I have a lot of opportunities to have close encounters with them, and allow me to shoot them at very close distances.
The frame above was to try and mimic a portrait of a person, with a very tight crop, eyes looking at the camera and nice even/soft lighting. The closeness gave this photo almost an unbelievable feel.
Try to link different styles of photos together, like portrait x wildlife, and you may get some interesting results.
Hope you enjoy this!
