It's easy to get rid of distracting element like cage bars--- with a little know- how!

1. Simply set your lens to telephoto.
2. Choose Av mode and hold the aperture as wide open as possible.
3. Approach the cage as close as safety possible and shoot.

Now, see how well the shot turn out. The cage bars are gone, and the animals look like they're in the wild.
