If you feel that your photos lack emotional impact, more often than not it's the distance between you and subject that is getting in the way of results.
When you view the picture on your camera's display, try zooming in on the subject. You might find that a tighter picture is better. Then go back to the camera mode, zoom in and take another one. Or, another way to get better photos is to use your body as the zoom: Move your body closer to your subject.
Either way, you'll find yourself with more intimate pictures.
About the photo: A remote camera operated by photographer Michael Nichols captured the tail of a crocodile entering its den at Chad's Zakouma National Park in March 2007.
