The technology of photographing animals is mature, but there are still many undiscovered animals?

Although the technology of photographing animals is very mature at present, there are still many animals that we have not found. That's because shooting technology and finding animals are two different things.

Shooting animals requires skill. For example, when we shoot birds, most of the time we use aerial photography. Scientists hatch a nest of geese to familiarize them with photographers. When they migrate, photographers can naturally shoot videos of their flight. Polar bears are hard to shoot. The photographer hid the camera in a disguise like an ice floe. Even so, sometimes clever polar bears will play with camouflage curiously and finally break the camera equipment.

There are also underwater cameras that shoot marine life. Now there are unmanned cameras that can dive to the depth of 1000 meters, but it is only limited to 1000 meters, and there is no way to shoot deeper marine life.

At present, scientists have found that there are about1500,000 species of known animals on the earth, including those that fly in the sky, run on the ground and swim in the water, as long as humans can see them. However, in the depths of the ocean, in the deep sea beyond human reach, there may be many unknown animals. The area of the ocean on the earth accounts for almost three quarters, but human exploration of the ocean is only about 5%.

At present, the depth of the ocean that humans can explore is only about seven kilometers, but they know nothing about the deep sea below seven kilometers. The deepest known Somali trench is more than 10,000 meters deep, and we don't know what unknown creatures will be at this depth. However, in the deep sea, the sea is dark without sunshine. It is not surprising that unknown marine life exists in such an environment.

However, the illumination distance of human lighting equipment in the deep sea is very short, and the backwater pressure is huge. How to overcome these difficulties has not been answered. Therefore, exploring the deep sea is still a huge problem for human beings, which has nothing to do with the level of photography technology.
