An underwater camera has many advantages over a conventional one. It's watertight, allowing you to use any lens, including macro and wide-angle lenses. It is also compatible with all types of underwater lighting, including underwater artificial illumination. Underwater cameras are definitely worth it. Here's an overview of the different features available in an underwater camera. The benefits of an underwater camera also extend to its ease of use.
The first step in using an interchangeable lens underwater camera is to choose the right model. Typically, these cameras are much more affordable than DSLRs. However, if you're a serious photographer and plan to spend a lot of time underwater, you'll need to consider more features than just the camera. A good underwater housing will have flash capabilities and compatibility with good underwater "wet lenses."
One of the best underwater lenses for photography is a super wide angle fisheye. Fisheye lenses have a wide field of view, and you can focus up to the front of the dome while shooting a close-focus wide angle. A 15mm lens gives you the flexibility to shoot both small and larger subjects. In addition, you'll be able to use a wide angle lens with a zoom, which is great if your subject is farther away.
A basic understanding of the relationship between the shutter speed, ISO, and aperture is necessary for successful underwater photography. Each of these settings determines how much light gets into the photo. Fortunately, many cameras have manual exposure controls. By choosing this mode, you can experiment with various light conditions and capture the perfect underwater shot. Manual exposure control is extremely important when you're photographing under water, because different scenes can require different exposures.
When diving, it is essential to carefully meter the background water for proper exposure. Once you have a good idea of how much light is available, you can adjust the shutter speed and aperture accordingly. You can also adjust the strobe power to achieve the right exposure. To make the process as easy as possible, the metering feature is built into the Nikon N90s. In addition to displaying the aperture and shutter speed, the camera has a "meter" display on the viewfinder.
There are several advantages of an underwater camera. First of all, it is small and it can go very deep. A camera that is designed for dry work can also be used for deep sea photography. Unlike other cameras, however, an underwater camera will require an additional housing. This protects the camera from the water and pressure. Housings are made of plastic or aluminum and allow the photographer to access the controls without having to dangle the camera. Second, it helps the photographer avoid scattering, which can cause blur in the images.
Third, an underwater camera can be used with interchangeable lenses. While the first three feet of water block nearly 50% of the available light, these cameras can capture more light. And because they are waterproof, you can use them with a variety of lenses. You can use interchangeable lenses with these cameras to improve the quality of your images. Another benefit of an underwater camera is its large sensor. Larger sensors allow more light to reach the camera.
When you're diving with your underwater camera, it's easy to be tempted to take up close-up photographs of all kinds of small creatures. After all, those National Geographic spreads are filled with gorgeous images of tiny creatures and their habitats. If you'd like to try your hand at nature photography, you'll want to start with small animals. These creatures can be surprisingly interesting, and you can practice your close-up photography skills by capturing them up close.
There are several ways to light your underwater subjects. Backlighting can be a great way to take pictures of translucent and hairy creatures. Simply place a light behind the critter and move into position so that the camera, light, and critter are in alignment. If you have difficulty getting the perfect lighting, you can use a strobe. But make sure you have enough room in your frame to move the subject. Do diving cameras scare fish? Let's find out!
