Here’s an example. I found this female cheetah and her cub one day in Kenya’s Masai Mara National Reserve. I got a decent shot of the two of them the first afternoon, but I felt I could do better. So, rather than run all over the park photographing different animals, I spent the next week—every day from before dawn to after dusk—with the two of them. And I’m glad I did. I got to know them and their habits, and they became so used to my car that I could get quite close without bothering them.
