One of the most curious facts that always surprises readers is this: There are more people who go to the moon than there are people who go to the deepest place on earth., under the oceans. That spot is in the Pacific Ocean, south of Japan, and the Mariana Trench under the US flag. here it is where the deepest photos are taken.
The depths of the oceans remain unexplored due to technical difficulties and the cost of the expedition to these points. In fact, you must know one of the descendants. neither more nor less James Cameron, famous movie director. Developed one of the most advanced capsules to record the depth of the trench in 3D. And therefore it is an important part of its history.
Difficulties going deeper than 10,000 m
The Mariana Trench reaches its deepest point at 11,034 m at the Challenger Deep. It extends approximately 2,550 kilometers with a width of 69 crescent. If we put Mount Everest inside, there are still thousands of meters to travel. Human survival is impossible without a specially prepared tool.
To give an idea, according to his own statements in the documentary made by James Cameron, it takes more than two hours to go deep. And the pressure is so high that the thickness of the submarine capsules is 90 mm. This is how they prevent oppression from destroying us.
If you want to experience an adventure in extreme depths, just wait for a new alliance. EYOS Expeditions and Caladan Oceanic To bring tourists back to the Challenger Deep. This trip cost 750,000 Euros per person.
We can find the photos, but when they manage to reach this depth, video usually saves more than stills. You can get much more than a single frame from a recording. But they carry at least one camera.
Maximum depth is seldom reached with a crew. The last one was released on 10 November 2020 by a Chinese team. Fendouzhe submarine (Chinese warrior). They set a record that has not yet been broken. They reached 10,909 m and collected biological samples, sediments and rocks from the seafloor.
They made 13 dives before the record, and in eight of them they exceeded 10,000 m. The most incredible thing about this expedition was that the mission was broadcast live by the official CCTV station in Beijing and served to show the world China’s technological progress.
The pressure here is 1,086 bar, which is more than a thousand times the normal pressure at sea level. The worst is inside. they found plastic, the result of contamination. The animals living there are also harmed by our presence.
How to take photos and videos at these depths?
Many countries fund these studies, but the most famous is that of the United States. ocean exploration, with one of the most complete pages on the subject you can find. We found most of the information here.
Because descending into the depths of the Mariana Trench is very complex and expensive, they usually prefer to descend to around 4,500 m by ROV (Remote Controlled Vehicle), an unmanned submarine controlled from a ship. Tied to the ship by a cable (Remember?Titanic‘?)
Ranging in size from a shoebox to a van, this high-tech equipment is modular, meaning that various elements can be added depending on the technology needed by the science team that hires it.
this ROVs Like David Wotherspoon, they have the strength of a rugby player but the skill of a neurosurgeon. Schmidt Ocean Institute. And they need eyes to operate remotely. And above all, light is something that does not exist in the depths of the earth.
The basic display equipment of these submarines is as follows. The brands of these cameras are not known to the general public. First of all, we find a system for localization Onsite Pacific Mini Zeus HD 1080i; scientific camera SULIS Submarine Z70With 4K resolution and 12X zoom; four HD cameras DSPL FlexLink HD Multi Marine Camera. And of course the DSPL SLS-6150 LED lighting and two additional Newtsun 500w LED lights.
The quality of these suits is impressive, but their features draw our attention. For example, the Sulis Z70 has a 12x Zeiss zoom lens, but the size of the sensor is remarkable, just one” and 20MP resolution. And it is so preserved that it weighs 13 kg.
This equipment is mounted around the ROV to be able to record all angles even to always be able to control the hub cable we mentioned. And they are prepared for both video and photography. All the photos we see of the depths were taken with this device.
James Cameron recordings
We can confirm that the best quality images we could find of the most extreme seafloor were taken by James Cameron in 2012. It took him two hours to reach the 10,898 m he reached. He sank alone on the ‘Deepsea Challenger’, a torpedo-shaped submarine made of fiberglass and a steel shell that can withstand 1,000 atmospheres of trench pressure, and which he helped design.
It was so well equipped that some compared it to an entire television studio. He managed to record the documentary in this way.Deep Sea Challenge 3D‘ was introduced in 2014. The frames in that video are the best and deepest photos ever taken.
Special cameras created for this diver were used there, because until then there was nothing similar. I am convinced that the experience accumulated in this project helped this director to have a very clear idea of how to record the film. second part of avatar.
But years have passed and today we find more advanced equipment offered by specialist companies such as Triton, capable of recording this wonderful BBC documentary. “Blue Planet II”
From a photographic technical point of view, the problems are many. Teams must withstand pressure above all elseavoid condensation and of course have sensors that support low light and allow true color to be recorded.
Actually, we don’t know the color of the depths as it depends on the color temperature of the equipment. And because the light never comes, we cannot know exactly whether what we see is real or not. However, in the meantime, we can look at the images of a place where there are only 7 people in the world.
