Which camera is better for underwater shooting? Selection of underwater shooting equipment

How can you go diving without leaving nice photos? Most of you should go with your friends and take pictures of each other. There are also some diving photographers who may have higher requirements for diving photography equipment, so it is very important to choose equipment and pay attention to underwater photography.

Cameras and lenses

Generally choose SLR or micro single body. According to different shooting themes and shooting environments, different lenses will be selected. The most commonly used lenses are super wide-angle lens, fisheye lens and macro lens. Later articles will have the recommendation and introduction of the fuselage and lens. The price of the fuselage varies greatly, from the cheap 3-4 thousand miniature cameras to the 4-5 thousand flagship machine full-frame cameras. A lens generally ranges from 2000- 10000, and generally buy 2-3 lenses.

Camera waterproof shell

The waterproof shell of the camera is used to protect the camera body from water, so that the camera body and the flash can communicate and provide the camera with good operability in water. A good waterproof case can operate all the buttons on the fuselage. Waterproof shell is divided into acrylic (plexiglass) material and aluminum alloy material. Acrylic is much heavier than aluminum alloy in air. Some camera waterproof shells have the function of vacuuming, and will prompt if there is water leakage. The price of waterproof shell ranges from 1 10,000 to 30,000.

Lens cover and telescopic tube

Because the focal length, diameter and length of the lens are different, different lenses need different lens covers, which together with the waterproof shell of the fuselage form a closed system to achieve waterproof. A suitable lens cover can accommodate a lower lens without forming black corners on the photo. Some lenses are long, and an extension tube will be added between the waterproof shell and the lens cover. Generally, the lens cover of super wide-angle and fisheye lenses will be spherical, while the macro lens will be flat. The price of these accessories ranges from1-2,000 to 8-9,000.

Flashlight arm

The underwater flash lamp is connected with the waterproof shell through the lamp arm. Generally, people will choose the lamp arm, which is convenient to adjust the position and angle of the flash under water, so as to obtain the ideal light supplement effect. Usually the lamp arm has 1-2 parts. If you have two flashlights, you need four arms for every two arms. The length of the arm is also different, depending on the subject matter. There are many kinds of lights with different effects. This will be described in detail in a later article. Prices range from tens of dollars made in China to hundreds of dollars imported.

Ball head and butterfly clip.

Used to connect waterproof shell and lamp arm, lamp arm and flash video lamp, waterproof shell and video lamp. Generally, you need 2-8 butterfly clips and 2-4 tees, depending on how to match them. One ranges from tens of yuan made in China to two or three hundred yuan imported.

Synchronous flash line

Used to connect the flash and the fuselage to realize the communication between the fuselage and the flash. Choose different synchronization lines according to the waterproof shell, fuselage, flash and the number of flash brands of the camera. Some combinations can realize TTL. The price is one or two thousand yuan. Of course, it will be much cheaper if you use optical fiber to flash.

Underwater flashing video lamp

For underwater lighting, generally need 2-3. The general market price ranges from 2000 to 8000.

Buoyancy arm

Buoyancy arm is a kind of light arm, but its volume is relatively large, which provides positive buoyancy and makes the whole underwater photography system maintain slight negative buoyancy or neutral buoyancy in water. The price of carbon fiber made of plastic varies according to its length, which is usually several hundred yuan.

Other accessories

There are anti-lost ropes, flash diffuser/diffuser, viewfinder, external display and so on.

10 parts

Some accessories can be DIY, and the effect is even better than that bought.

Common equipment combinations include the following:

Fuselage: Nikon D8 10, Sony A7RII, Canon 5D3.

Lens: fisheye, wide angle and macro of original or sub-factory of each brand.

Waterproof shell: Ikelite, seasea and nauticam correspond to the fuselage waterproof shell.

Lens cover: Generally speaking, the fuselage and waterproof shell are determined, and the length of lens cover and telescopic tube required for the corresponding lens can be found from the manufacturer of waterproof shell in official website.

Two flashlights: commonly used models are YS-D 1/D2 and DS 16 1. Two lamps, two buoyancy arms, six butterfly clips and a matching tee. A flash of light

2. The control ability of neutral buoyancy determines whether the photos you take with gopro are clear or fuzzy, so it is particularly important to practice neutral buoyancy when learning to dive (it is recommended to experience it carefully during your study).

3. When the yellow filter is used above10m, the red filter is suitable for use from 20m to10m and below 20m. I suggest buying a flashlight directly or playing a waterproof flashlight to help fill the light.

4. Don't use a flashlight, put on a filter. The deeper the water is underwater, the less sunlight hits it, so the less colors the camera can capture. This is why you need to add a filter or polish it. One of them will do.

5. The question of whether gopro should buy a black version or a silver version. The black version has more 4k videos, but there is no monitor to match it. The white version has a monitor, but there is no 4k video. I suggest you use the white version. It is cumbersome for ordinary players to record 4k video.

6. Besides gopro, what other cameras are there? Sony's black card, with waterproof shell, can directly adjust the shooting balance underwater and is not easy to be burned, but it is also limited to underwater photography. Fortunately, you can't wear it on your body to play extreme events such as paragliding or skydiving like gopro, and the angle is not as wide as gopro, so buy a camera to see which aspect you want to play more.

7. Taobao bought dozens and hundreds of SLR waterproof bags. If it can't get down below 10 meter, it will get water. Stop messing around. The underwater waterproof shell of Quan Huafu SLR is generally more than twice as large as that of SLR, so don't think too much. Damaged frame waterproof shell can be found within 3000. You can try anyway. I haven't tried.

8. Before getting into the water, let the people on board take the camera and get into the water by themselves, and then let others give it to you. Diving with a camera is easy to damage the camera.

9.ow is generally not allowed to bring your own camera into the water. After all, this is a teaching process. You know, it's okay to be cute. After learning to dive freely.
