Some tips for Underwater portrait photography

Views:125     Author:Site Editor     Publish Time: 2019-08-09      Origin:Site

We are curious about the underwater world, because we rarely have the opportunity to see the landscape in the water. Nowadays, more and more photographers are not satisfied with shooting on land. They are turning to shooting underwater world. But it is not easy to take good pictures under water. Today I've brought you some underwater shooting techniques to make your underwater shooting more comfortable.

 

Matters Needing Attention for portrait photography

1. The best time to shoot is around noon.

Cameras need protective shields for underwater photography. The best choice for underwater photography is at sunny noon, when the sun is at the top, the sunlight is almost vertical to the surface, rarely reflecting, and the brightest in the water.

 

2. Attention should be paid to the refraction of light by water.

Never assume that the distance you see underwater is the actual distance, because the refractive index of water to light is about 1.33 times that of air to light. So the object in the water looks 1.25 times larger than the actual volume, and the distance of sight is about 25%. Underwater scenery looks 0.75 meters away, the actual distance is about 1 meter. Do not create illusions when focusing manually.

 

3. It is advisable to select medium and high speed film

Because of the weak light in water, it is difficult to stabilize the camera while swimming in water, and it is difficult to solidify the picture with low-speed film. Although this problem can be solved by using ASA800 degree fast film, the image grains are rough and the color restoration is not ideal. Therefore, it is suitable to use medium-speed film from ASA2 00 to ASA400.

 

4. Auxiliary light source is indispensable

When the water depth is about 10 meters, only the use of flash lights and other auxiliary light sources to illuminate can ensure the correct restoration of photo color.

 

5. Close to the subject

There are also suspended particles in the transparent water. The farther away the camera is from the subject, the worse the clarity of the picture is. So try to use wide-angle lens to shoot close to the subject.

 

6. Bring sufficient diving equipment

We should try to carry enough diving equipment, which will bring us great help. The diving backpack can help us pack some things. We carry a diving knife. Its main function is to use it as a tool for self-rescue when we are entangled with ropes, fishing nets and aquatic plants underwater. Essentially, it is part of our security equipment. In addition, most diving accidents occur on the surface of the water, and ships in the past are the main killers. When we finish diving and prepare to rise to the surface, we don't know the situation of the water, so we need to pull the diving buoy out of the water before climbing, so that we can notify the passing boats, let them know that there are divers underwater and pay attention to avoiding.

 

Tips for Underwater Portrait Photography

Be Open To New Things

Underwater, everything is different. Because photographers and models are close to zero gravity, equipment and clothing are difficult to control. So no matter how experienced a photographer is, when he first goes to the bottom of the water, he may feel like a novice, trying everything from the beginning.

 

Don't Buy Underwater Equipment Cheaply

Waterproof enclosures can't be saved at all, because when your camera lens is worth tens of thousands or even hundreds of thousands of dollars, a little leakage can cause disastrous results and also affect the quality of the picture. So waterproof equipment must be professional. If you just want to play, consider buying GoPro or renting waterproof equipment to see if you like underwater photography.


 

Understanding Clearly that Different Water Quality is Different

Pools, seas and freshwater lakes are also different, as is the density of water. For example, the model's eyes may not be able to adapt to chlorination pools. There may be jellyfish and other dangerous organisms and garbage in the sea. Freshwater lakes are recommended.

 

Making Use of Wide Angle Lens

It is better to close the person in underwater photography. If it is too far away, the picture may become blurred because of the muddy water quality. But it also depends on the content of the shooting.

 

Learning to Sink Under the Water

The key to staying underwater is not to hold your breath, but to let all the air out. The less air in the lungs, the less buoyancy you will face. If you're shooting at the bottom of the ocean, you need to use diving equipment.

 

Be Patient with Models

It's extremely difficult to do facial movements well under the water. They can't breathe and need be photographed beautifully. But they can't see the camera very much and don't know what you are doing. They want to make her do what they want, so they need to give the model enough time to get used to it. For most models, the photographer will first let them practice sinking underwater, teach them to breathe out oxygen, when the model feels that sinking underwater is okay, then guide the movement or expression.

 

Learn to Shoot fast

Even if the water is not cold, underwater photography takes a lot of energy, especially when the model takes various postures under the water. The nose and ears also get water. It's very tired. Photographers prepare bottles of drinking water and some dry food to eat during breaks. Similarly, when soaked in water for too long, skin may begin to wrinkle and make-up may disappear. So in order to shoot the effect, it is better to finish shot faster.

 

Have an assistant

Underwater photography can be dangerous, especially when models wear skirts with a lot of fabric. Models can't organize themselves properly, so they need help from others. At the same time, having an assistant watch on the water can also ensure everyone's safety. Assistants can also handle lighting, adjusting equipment, etc., which will be more efficient.



Later Stage of Acceptance

When an underwater photograph or film comes out straight, the tone can be very unsatisfactory. But sometimes it's not a matter of lighting or camera. It's the wonderful pictures we see on the internet. In fact, it's more or less post-made. For example, color mixing and debris removal, strange reflection, bubbles, etc., so try first and then make the picture better, before considering the issue of equipment.

 

This is all about underwater photography skills, I hope they will help. At the same time, I hope you can learn these skills and take good pictures.
