The Basic Principles Of camera underwater housing



Last weekend at the shore was deadly to your digital camera? I'm sorry, but these are risks that have to be taken into consideration when utilizing non-water resistant devices in places like seaside resorts. If you'd like help from a friend, buy an underwater camera to use in these conditions. I guarantee you that you won't regret.



In terms of the sum to spend, don't be alarmed: unless you've got professional needs, you can bring home a good product spending less than 100 euros, but in addition, there are versions offering higher quality or greater resistance costing a little more but offering all you need to churn out photos you can be proud of, despite the intense problems.



If you are looking for a camera to take to the sea or the pool, in short, you're right in the ideal place! In this page, I'll clarify, in actuality, all you need to know about the products within this class as well as the technical or structural features that you must observe within an underwater camera prior to making the buy. Beneath, finally, I will propose the best models divided by price ranges.


Layout

The plan is the most essential feature of an underwater camera, and for design does not mean clearly only the aesthetic look, but also the structural characteristics of the device that allow it to resist and work underwater or in the presence of places where not it's unusual to wet the camera.

The plan of a camera of the type is distinguished by many gaskets and technical solutions that prevent water from reaching the delicate internal components of the apparatus so it may be used in virtually all environments. Underwater cameras are subdivided substantially into two chief branches.

Underwater compact cameras would be the conventional ones, characterized by small and almost always pocket size. They possess the aesthetics of a traditional camera, but the external structure prevents the entry of liquids and, often, even dust.
Action camera underwater - that the activity cameras are small cameras aimed especially at those who record action videos, both sports and experience to catch their actions in distinct locations. They're characterized by their extremely small size, easy portability and the ability to use accessories that can be hooked through which you desire. Frequently the impermeability is ensured by housings which aren't necessarily offered.

Resistance to water

The water resistance is obviously the main characteristic of an underwater camera and is often denoted by the maximum possible depth of immersion. The low end versions can guarantee dives up to a couple of tens of yards, while the higher ones in the range can even allow you to exceed 100 meters. If you simply need to bring it to the pool or the sea, of course, you can even manage to invest hardly any!

Additional resistances
In the marketplace there are also models which, along with water resistance, also provide other types of resistance. On a digital underwater camera you could also get resistance to shocks or falls (generally at a person's height, therefore as much as two meters), immunity to extreme temperatures (generally from the cold, up to -10 ° C) and the common resistance to entry of dust . Electronic components are sensitive not only to water, but also to sand, soil and smaller particles that could compromise performance.

Dimensions and weight

It also naturally evaluates the weight and size characteristics , because they're cameras which are born to be transported anywhere. On the market you will find specially compact versions, together with the small ones who - since I told you a small above - are the action cams . The latter are mainly oriented to video recording, while for the photo shoot I suggest you rely on a compact camera with water resistance .

Technical features

So far we have analyzed only the structural and design features of an underwater digital camera , but the actual shooting quality is given by the integrated technical features and the features present. These are the same concepts that we find on traditional cameras, and that is worth review a bit 'before choosing the model of underwater camera right for your needs.

Sensor and resolution

The sensor is the fulcrum of the camera, the component which makes it feasible to transpose the lighting into an electronic file via a picture chip linked to it. It's distinguished by numerous photodiodes which catch the light transmitted from the lens amassing the information of brightness and colour, data that are then processed by the more info processor to become "RAW" or compressed ( JPEG ) files to save space in the memory card .

The detector determines the highest resolution of this picture: the larger 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 shot but its definition, while the quality is check here defined by a whole series of components that work synergistically to offer detail, colour fidelity and proper values of vulnerability in the lighting and at the shaded regions.

Concentrate

You've certainly heard of the focus , which can be always - or almost - automatic in today's cameras. The focus allows you to highlight a specific subject of the environment which you would like to catch (or blur other people, far or close). The several models in the marketplace permit you to concentrate from certain distances, starting from 15 or 20 centimeters until you get to very high distances known as "unlimited". If you would like to shoot macro photographs , really close, consider specific models that allow you to do it. On an action camera the focus is fixed, and can not be managed in any way.
