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

How can you go diving without leaving nice photos? Most people should go with 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 pay attention to underwater photography in how to choose equipment.

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. The fuselage and lens will be recommended and introduced in later articles. The price of the fuselage varies greatly, from 3-4 thousand cheap micro-cameras to 40-50 thousand full-frame cameras in flagship machine. A lens generally ranges from 2000 to 1000, and generally you will buy 2-3 lenses.

Camera waterproof shell

The waterproof shell of the camera is used to protect the fuselage from water, so that the fuselage and the flash can communicate and provide good operability of the camera 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 vacuumizing, and there will be a prompt in case of water leakage. The price of waterproof shell ranges from 1000+ to 30000+.

Lens cover and telescopic tube

Because the focal length, diameter and length of the lens are different, different lenses need different lens covers to form a closed system with the waterproof shell of the fuselage 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 is flat. The price of these accessories ranges from1-2,000 to 8-9,000.

Flash arm

The underwater flash lamp is connected with the waterproof shell through the lamp arm. Generally, everyone 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 fill light effect. Generally, the lamp arm will have 1-2 segments. If there are two flashlights, each arm needs four arms divided into two sections. The length of the lamp arm is also different, depending on the subject. There are many kinds of lamp arms, and the use effect is different. The following article will introduce it in detail. Prices range from domestic tens of yuan to imported hundreds of yuan.

Ball head and butterfly clip

Used to connect waterproof shell and lamp arm, lamp arm and flash video lamp, waterproof shell and video lamp. Need usually needs 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.

Flash synchronization line

Which is use for connecting that flash lamp and the fuselage to realize communication between the fuselage and the flash lamp. Choose different synchronization lines according to the number of camera waterproof shell, fuselage, flash and flash brands. 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 lines to flash.

Underwater flashing video lamp

For underwater lighting, generally need 2-3. Generally, the price on the market ranges from 2000 to 8000.

Buoyancy arm

Buoyancy arm is a lamp arm, but it is relatively large and provides positive buoyancy, so that the whole underwater photography system can maintain slight negative buoyancy or neutral buoyancy in the water. Made of plastic carbon fiber, the price varies according to the length, generally several hundred yuan each.

Other accessories

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

10 parts

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

A set of common equipment combinations are as follows: body: 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 waterproof shell of the fuselage.

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

2 flashlight: the commonly used models are YS-D 1/D2 and DS 16 1. 2 lamp arms, 2 buoyancy arms, 6 butterfly clips and matching ball head seat. Flash synchronization line.

Tips for underwater photography: 1.gopro sports camera is generally the most basic underwater photography equipment on the market.

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 study hard in your study).

3. Use a yellow filter above 10 meter, and a red filter is suitable for 20 meters to10 meter. Below 20 meters, I suggest buying a flash or playing a waterproof flashlight to supplement the light.

4. Don't use a flashlight, wear a filter. When underwater, the deeper the water, the less sunlight can reach, so the less color the camera captures, so you need to add a filter or polish, and both will do.

5. Is it a question of buying the black version or the silver version of gopro? The black version has more 4k video recordings, but there is no matching monitor. The white version has a monitor, but there is no 4k video recording. 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 has a waterproof shell, which can adjust the balance of direct underwater shooting and is not easy to paste, but it is also limited to underwater photography. You can't wear it on your body to play extreme events such as paragliding or skydiving like gopro, and it's not as wide as gopro, so buy a camera to see which aspect you want to play more.

7. Dozens and hundreds of waterproof bags for SLR bought on Taobao, if they don't reach 10 meter, they will get into the water, so there is no need to toss. The underwater waterproof shell of Quan Huafu SLR is generally more than twice as big as that of SLR, so don't think about it. The waterproof shell of the residual frame can be found in Taobao within 3000 meters. You can try it. I haven't tried anyway.

8. Before launching, let the people on board take the camera, launch it yourself, and then let others hand it to you. It is easy to damage the camera when diving with it.

9.ow Under normal circumstances, it is not allowed to bring your own camera into the water. After all, it is a teaching process. You know, you can be spoiled or cute.
