What are the skills of underwater photography? By mastering the shooting time, we can effectively capture the rare underwater scenery, especially the use of smooth light, which can make the shooting more smooth. It is very important to be close to the shooting theme in order to clearly show the underwater ecology. Next, I sorted out the skills of underwater photography for your reference!

Close to the shooting theme.

The density of water is 800 times that of air, so no matter how good the resolution is, no matter how strong the flash is, it will be greatly reduced when it reaches the water surface. If you want to take high-quality photos, you should be as close to the theme as possible. The close-up of tiny aquatic organisms by macro lens can often capture extremely bright colors; A super wide-angle lens with a long depth of field, even a fisheye lens, is suitable for shooting large scenes such as sea fans, coral reefs or people. If you use a consumer-grade digital camera, you can use a wide-angle end, which is optically anti-shake and has high sensitivity.

The irradiation distance of flash lamp in seawater is usually within 1 m, but it is easy to cause uneven light supplement because it is close to the subject. The solution can be to install an extravehicular flashlight in the diving bag, and use flashlights in different directions to solve the problem of uneven light compensation through light triggering or radio triggering.

Matters needing attention in underwater shooting

Maintaining its own neutral buoyancy is the primary condition for underwater shooting. There is three-dimensional space under the water surface, and there is water flow. When shooting, unlike standing on two feet on land or even using a tripod, buoyancy control is very important training. Keeping even breathing and gentle body movements helps to get close to and then photograph underwater creatures; Excessive and improper movements will often scare fish and small creatures, and careless frog shoes will also raise sediment at the bottom of the water, which will affect the quality of underwater shooting. However, although it is difficult to fix the position in the water, it also lacks the restriction of gravity. All-round and multi-angle shooting makes underwater photography have a bigger angle. In addition, in addition to the creatures and landscapes in the water, diving companions are also extremely important shooting elements. Don't forget to take pictures of divers and fish swimming in the water when taking pictures in the water!

Mastery of shooting time

A large area of water will absorb and reflect light, so the underwater light is dim, even if it only snorkels to 1? 5 meters, it is also easy to take blurred photos due to insufficient light. It is recommended to use 1 1 in the morning. Between two o'clock in the afternoon, when the sun is strong, shoot in the water. At this time, the direct light of strong light source and ceiling lamp is not suitable for shooting on land, but in water, due to less loss of reflected light, the brightness under the water surface can be increased and the shooting success rate can be improved. If it is midsummer, even 9 am to 4 pm is the right time for snorkeling. If you can't specify the diving time because you join a snorkeling group, it is recommended to use high ISO to increase the shutter speed and adjust the aperture to the maximum aperture, which will help to improve the shutter speed. In addition, you can also use wide-angle shooting, because of its large aperture value and low requirements for safe shutter, which is suitable for shooting in underwater environment.

It's easiest to follow the light.

When snorkeling, because the diving depth is shallow, the light can easily penetrate into the water, so you can take quite bright photos as long as you improve ISO. At this time, if you can use the light source to find the subject, you can shoot the bright colors of fish and coral reefs without turning on the flash.

As for backlight, unless you are a professional player, it is not recommended to shoot against backlight, because the flash output of general digital cameras is generally insufficient. At this time, if you forcibly fill the light, it will only increase the consumption of battery power, and even if the light is filled successfully, too many positive light sources will make the subject look boring.

Feeding is also a means of shooting.

If you want to photograph underwater creatures, you must first understand their habitats, living habits and active seasons. Only in this way can you shoot the most beautiful shots in the shortest time, instead of shooting fish at random, all by luck. In addition, if you want to attract fish to your side to shoot, please ask a coach or bring some bait such as raw saury or shrimp to attract fish to eat. It should be noted that excessive feeding not only easily affects the original living habits of organisms, but also may make the water quality dirty, thus affecting the clarity of shooting. On the contrary, it will have the opposite effect and will not play a substantial role in adding points.
