Shoot ant caves in the animal world and follow how ants shoot them.

Most of them were raised and photographed by the crew in special breeding boxes with the assistance of animal experts. The box on one side of the camera is made of glass, and the cross section of the cave is directly visible, which is convenient for the crew to observe, distribute light and shoot.

In many animal documentaries, although animals look wild, they are often raised artificially. For example, birds such as grey geese in the Oscar-winning documentary "Migratory Birds" are raised and trained by photographers themselves, aiming to make animals close to humans and eliminate animals' fear of shooting equipment and transportation.

If you really need to shoot in the wild, you often need to disguise the camera equipment as natural objects such as stones and stumps to avoid disturbing the living environment of animals. If shooting at night, infrared imaging technology is generally used to avoid using visible light illumination.

At present, documentaries of this kind of theme are mainly shot by teams from developed countries in Europe and America, but there are few domestic works and the level is far from the same. After all, documentaries consume a lot of manpower, material resources and time, with huge investment, narrow domestic market and difficult export. So basically no one wants to do it.
