*Focus on your subject and wait until it does something Interesting* is some or the best wildlife photo advice I’ve received. An apple might not do anything interesting, but for light, people, animals, action, birds, etc. this can often make a good photo GREAT.
Consider the series of three photos below. This first one is a nice shot of the bird, but the second one is made so much more intriguing when the bird opens its mouth slightly. The final image adds even more intrigue with the splashing water. Some times we’re too quick to move on to the next location or subject. Patience, and observation will help you to see more at first glance, and opportunities might come along that you did not expect.
