Watching the documentary series "BBC Life", I was shocked. How were these shots taken?

These are all taken with some special lenses.

Of course, the hard work of the photographer is also indispensable

1. Fix the miniature camera on an animal so that you can capture images of similar activities of the same animal. Of course, editing and processing will also be done later.

(I once saw in the Animal World that a photographer tied a miniature camera to the body of an eagle and captured the scene of it hunting hares from high altitude).

2. Use a telephoto camera. Of course, this method will be very hard for the photographer.
