Underwater photographs always create shimmering images and unique. If you have not tried this style shooting, the following guidelines will be of much help to you.
Underwater photography is a unique shooting style, the images taken in this way quite eye-catching and attractive but to capture such images requires experience and technical and expensive equipment. If you have a beach trip, try to practice and shoot under water at some guidance in this article.
Practice in pool:
If you plan to take underwater photographs you should try shooting in a pool. Indispensable is a protective bag, most of the camera point-and-shoot and DSLR are available common plastic bags to hold the camera and lens. This type watertight bag, and can be used to capture without any effect due to the water. Also a polarizing filter reduces reflections unwanted shine from the water.
Practice remain underwater for long periods and keep the camera steady. Low ISO settings to get a smooth images with no noise particles, a shutter speed of 1/250 sec or more. You can use the flash on the camera when shooting in the pool to freeze the motion. Wear goggles if you can not keep your eyes open under water a long time and try to shoot some funny photos with people who are swimming in the water.
Splitting the water surface:
Major technical challenges that photographers face when wishing to photograph water surface splits is the difference between the value of the exposure of the image above than below the water surface. This occurs due to refraction under water, affecting the upper part. However, this can be overcome by using a dedicated filter split diopter.
Keep an underwater camera steady is a challenge for anyone, because water is always moving. So people need to practice diving to capture the comfortable and familiar with the movement of the water before making underwater photographs. Do not hold the camera with one hand, can also ask a friend or a rock to stabilize the body.
When underwater photography, you will need to use a dedicated flashlight Flash, also known as a strobe. A conventional flash will not be strong enough to shoot under low light marine waters. In such conditions, if set at its lowest ISO can cause noise particle images.
The recommended settings:
When taking pictures underwater, you should choose the lowest ISO you can, to get images withou noise. You’ll need a shutter speed of 1 / 125s – / 500s to freeze motion – such as when shooting a school of fish. Use a small aperture (f / 11-f / 20) to get the depth of field, clearly objects both in the foreground and background. Shooting in RAW mode for color correction easier.
Equipment is recommended for underwater photographs :
Finally, as mentioned above, the waterproof bags for cameras is necessary when shooting underwater. You will need a flash if shooting in the dark waters.
The best type of lens for underwater use and wide-angle macro lens. Telephoto lens is useless because it can not get enough light to produce clear images.
