How Do Underwater Cameras Work



How do Underwater Cameras Work?
Underwater Cameras are cameras that are specially designed for​ underwater use or​ in​ circumstances that requires protection to​ prevent any water and​ pressure damage .​
There are many types of​ underwater cameras, depending on your budget and​ uses.
There are underwater cameras that are simply disposed of​ after use .​
These are the​ cheapest type of​ underwater camera available in​ the​ market .​
They have the​ capacity to​ take between 20 to​ 30 pictures, and​ photos can easily be developed .​
They are waterproof enough to​ be used in​ harsh rain and​ snow storms, and​ are usually tolerant of​ being fully submerged up to​ twenty or​ thirty feet .​
There are also underwater cameras that are cheap reloadables .​
These cameras are designed with economy of​ price in​ mind .​
These are very similar to​ disposable underwater cameras, expect that the​ user can replace the​ film and​ use the​ camera multiple times .​
They are usually capable of​ greater water depths than their disposable counterparts .​
New generation cameras have resolutions in​ the​ 3-4 megapixel range and​ can take excellent quality pictures underwater .​
These cameras offer options for​ every level of​ diver and​ snorkeler .​
For the​ experienced diver/photographer who wants more control over the​ camera functions .​
The Advanced-Dive control system allows users to​ manipulate resolution, light sensitivity (EV), exposure modes and​ much more while underwaterwhile the​ Easy-Dive control system is​ the​ perfect choice for​ divers seeking a​ simple underwater photo system that produces breathtaking results.

Underwater cameras are designed for​ one-Button-Operation and​ can be set to​ Land or​ Sea modes plus modes that take into account the​ unique aspects of​ underwater photography .​
Cameras also feature three dedicated underwater external flash modes, allowing for​ more exposure control when using an​ external flash .​
For perfectly lit photos in​ any situation, users can toggle among Macro Flash, Portrait Flash and​ Far Flash modes, which adjust exposure based on camera-to-subject distance.
While an​ on-camera flash helps illuminate objects below the​ surface, cameras are also compatible with external flash units, which ignite the​ vivid colors of​ the​ underwater environment and​ allows users to​ illuminate objects from different angles .​
Because the​ external flash is​ a​ unit activated via the​ on-camera flash, no sync cord is​ necessary .​
Set the​ camera to​ External Flash, and​ it​ automatically de-activates the​ digital pre-flash.
To compensate for​ low-light conditions that naturally occur as​ divers travel below the​ water's surface, cameras can adjust the​ shutter speed and​ aperture automatically to​ compensate for​ difficult light conditions, ensuring vivid images without worry of​ underexposure .​
Photos can be composed via a​ large color LCD monitor on the​ back of​ the​ camera; or​ users can frame subjects through a​ top-mounted SportsFinder .​
Either way, composition is​ simple, even when viewing subjects through a​ dive mask .​
To help conserve power during underwater adventures, users often shut off LCD monitors while the​ camera is​ on and​ compose photos using large top-mounted viewfinders.
With the​ many technological advances of​ recent years, underwater photographers now no longer have to​ compromise on quality .​
Users are almost guaranteed to​ return to​ land with a​ stunning set of​ images.
