During the entire existence of advanced technological devices, oceanologists have not managed to switch to regular large-scale study of great depths. Despite the annual missions, only 2-5% of the world's oceans are explored. This photo was taken using the light painting technique (Light painting is a long exposure technique with moving different light sources in front of the lens. You can also highlight objects or move the camera itself). Everything was done in real time in one shot without using Photoshop. Small color correction.
