How Many Factors Effect Underwater Camera Photograph?

The visibility in the water is not high, and the visibility in the water is 30 meters. The visibility of scenery shot on land is a few kilometers less, and the camera can record many details. However, underwater camera photograph are blurred, and a waterproof shell is covered in front of the lens, so the overall underwater picture quality is not good.  

And most of photographers are photographed by professional photographers or winners of photography competitions, and cannot represent the average quality of the camera. But at least you can see that the camera effects of different levels of cameras can be very good in the end, of course, the premise is that the underwater photography technology is better.

◆ The depth of field

It is difficult to take macro shots with a small depth of field. The larger the bottom, the smaller the depth of field. The smaller the depth of field, the harder it is to focus. Focusing in water is not as easy as on land and requires a lot of practice. Not only macro, sometimes wide-angle, wide aperture, easy to lose focus. Many people buy full-frame cameras in order to have a better blur effect when shooting portraits. This is a disadvantage most of the time in underwater photography.

◆ High feeling

The higher the sense, and the better the effect of the photo. The underwater light is often very weak, so we like the high-sensitivity body. When you buy a body, you can choose a camera with the same high-end and better feel. But then again, if the flash is used, the general sensitivity will not be very high. If you use natural light to shoot underwater, you need choose a camera with high sensitivity. 

◆ The camera latitude

When latitude is encountered, the difference in light and shade recorded will be greater. Underwater camera photograph also requires a camera of high latitude. A very classic composition is to shoot from below the underwater animal to the water surface. The water surface is definitely brighter than underwater, so this is a backlight shot. So backlit shooting is very addictive and forgiving. At the same time, due to the use of the flash under water, it is easy to cause a relatively large light ratio. But if you mainly shoot macros, latitude doesn't matter, because you can control the exposure of the entire frame to a suitable range.
