best underwater camers - An Overview



Last weekend at the shore was fatal to your digital camera? I'm sorry, but all these are risks that must be taken into consideration when using non-water immune apparatus in places like seaside resorts. If you want help from a friend, buy an underwater camera to use in these conditions. I assure you that you won't regret.



As for the sum to spend, do not be alarmed: unless you've got professional needs, you can bring home a fantastic product spending less than 100 euros, however there are also versions that offer higher quality or increased resistance costing a bit more but offering everything you want to churn out photographs you may be proud of, regardless of the intense conditions.



If you're looking for a camera to take into the sea or the swimming pool, in short, you're right in the ideal place! Within this page, I will clarify, in fact, all you have to know more about the products in this category as well as the technical or structural characteristics that you must observe within an underwater camera before making the buy. Below, finally, I'll propose the best models divided by cost ranges.


Design

The plan is the most important feature of an underwater camera, also for design doesn't mean obviously only the aesthetic look, but the structural qualities of this device that allows it to resist and work underwater or in the presence of areas where not it is unusual to wet the camera.

The plan of a camera of this type is distinguished by numerous gaskets and specialized options that prevent water from reaching the delicate internal elements of the device so it can be used in almost all environments. Underwater cameras are subdivided into two main branches.

Underwater compact cameras - would be the traditional ones, characterized by little and almost always pocket size. They possess the aesthetics of a conventional camera, but the external structure prevents the entrance of liquids and, often, even dust.
Action camera underwater - that the action cameras are little cameras aimed particularly at those who capture action videos, both sports and experience to capture their actions in different areas. They're characterized by their extremely small size, easy portability along with the ability to use accessories which may be hooked wherever you desire. Often the impermeability is guaranteed by housings that are not necessarily offered.

Resistance to water

The water resistance is clearly the principal characteristic of an underwater camera and is frequently denoted by the highest possible depth of immersion. The low-end versions can guarantee dives of up to a few tens of yards, while the higher ones at the scope can even allow here you to exceed 100 meters. If you should simply make it to the pool or the sea, obviously, you can even manage to spend hardly any!

Additional resistances
On the market there are also models which, along with water resistance, also offer other kinds of immunity. On a digital underwater camera you might also have resistance to shocks or drops (generally at a man's height, therefore as much as two meters), immunity to extreme temperatures (usually from the cold up to -10 ° C) along with the frequent resistance to entry of dust . Electronic elements are sensitive not only to water, but in addition to sand, soil and particles that could compromise performance.

Dimensions and weight

Additionally, it naturally evaluates the size and weight characteristics , because they're cameras that are born to be transported anywhere. On the market you will find specially compact models, together with the small ones that - as I told you a little above - would be the activity cams . The latter are largely oriented to movie recording, while for the photo shoot I suggest you rely upon a compact camera with water resistance .

Technical attributes

Thus far we have analyzed only the design and structural characteristics of an underwater digital camera , but the true shooting quality is given by the integrated technical aspects and the attributes present. These are the same concepts that we find on conventional cameras, and that's worth review a bit 'prior to deciding upon the model of underwater camera right for your requirements.

Sensor and resolution

The sensor is the fulcrum of the camera, the component which makes it possible to transpose the lighting into an electronic file through an image chip linked to it. It is characterized by numerous photodiodes which catch the light transmitted by the lens collecting the information of brightness and colour, data that are then processed by the chip to become "RAW" or compressed ( JPEG ) files to conserve space in the memory card .

The sensor determines the highest resolution of this photograph: the greater the amount of photodiodes and also the higher the computation of the pixels within the photo. The resolution, which in digital photography is quantified in Megapixel , is not synonymous with the quality of the shooter but its definition, although the quality is defined by a whole chain of elements that work synergistically to offer detail, colour fidelity and proper values of exposure in the lights and at the shaded regions.

Focus

You've certainly heard of this focus , which is always - or almost - automatic in the present cameras. The attention permits you to highlight a specific subject of this environment which you want to capture (or blur other people, far or close). The several models in the marketplace permit you to focus from certain distances, beginning from 15 to 20 centimeters until you get to very high distances known as "infinite". If you intend to shoot macro photographs , really close, consider specific versions that enable you to take action. On an action cam the focus is fixed and can't be handled in any way.
