When he isn't out in the bush, which is just about every other day, Collins can be found giving lectures at the Four Seasons lodge on photography topics like composition and processing.
As we spent a day together on the Ikoma Circuit in the Serengeti, Collins regaled me with a piece of advice he gives to all amateur photographers: "Stop centering the animals!"
According to Collins, it's boring and being boring is the cardinal sin of photography. The brain reads a photograph much like it reads a book, with the eyes moving and the brain processing from left to right. That means if you get the animal in the left corner of your shot, your audience immediately becomes much more engaged.
His other advice: "Pay attention to the eyes." You want to get the animal looking off to the right, so that the viewer's gaze is shifted in the direction of the rest of the scene or you want the animal looking directly at you, to engage the viewer.
Here are Collins' other tips, broken down by safari animal. Do as he says and you're sure to bring back some stellar photographic memories.
Lions are the king of this savannah and they know it. "They have so much character in their faces. The ideal shot is the lion looking right at the camera with a nice dark mane," Collins explains. "I like to capture them walking toward the camera to give the photo some movement." With the lion, even more so than any of the other animals, you want to focus on the eyes. The eyes are where you really begin to tell the lion's story.
