The Role Of Digital Camera Cases

A digital is a precision instrument that can be severely affected if it falls or bangs on something hard. Digital camera cases are not only manufactured to be aesthetically pleasing to the eye but many are made to protect the digital camera. This is actually the primary role of digital camera cases, to protect the camera from damage and harm as it is stored in it.

Protection For Your Digital Camera

Digital cameras have grown smaller and smaller through the years, especially the point and shoot ones. These smaller digital cameras are often stored in digital camera cases that can also be placed inside the bag. Most digital camera cases of the smaller variety are made to withstand a low fall and to protect your camera from scratches. These digital camera carrying cases have the capacity to envelop your digital camera to an extent that some can even protect from water damage. This vital role of digital camera cases is something that one needs to remember when purchasing digital camera cases.

Not all digital camera cases are built alike. Some manufacturers actually produce cases that are aesthetically pleasing but offer no protection whatsoever to the digital camera in them. One must be scrupulous when purchasing a camera case.

Storage

Another role that digital camera cases play is that of a storage case for extra batteries and media containers. These are vital to a successful photo session as sometimes, the user may get carried away with taking pictures that he will need the extra batteries and the extra flash card or memory stick to fill up with more pictures. Although not all digital camera cases can accommodate too many batteries and much media, many offer the user some space to keep them all in one container. Most media storage devices are flat and thin therefore making them easy to place in camera cases. It is the bulky batteries (especially the ones that are shaped like ordinary batteries) that may need more space.

Some digital camera cases have slings to put around the wrist while others are made to be stuffed in a bag. These camera cases are usually opened and closed using a zipper although there are others that have different types of opening and closing devices.

The design of a particular digital camera case can also help you remember how it looks. Some designs are also very helpful with regards to how slim they are to fit in a bag or how conspicuous they are.

The First Step in the Process: Solar Water Heating Panel

When individuals choose to implement a solar water heating system in their homes, they will have to choose either an active or passive solar water heating system. Passive systems are usually used in warmer climates where the temperatures in the winter time do not reach freezing, or do not stay there for long periods of time. Active solar water heating systems are used in colder climates, especially the indirect circulation systems which use antifreeze in the pipe coils to heat the water that is in the storage tank. No matter which system is used, there is also a choice that has to be made in the type of solar water heating panel for the system to work.

Types of Panels

There are three basic types of solar water heating panels. The first is called a flat plate collector, which is usually a glazed flat plate that is insulated and contains a dark absorbent plate that sits beneath at least one glass or plastic cover. There are some flat plate solar water heating panels that are unglazed and have an absorbent plate that is made from metal instead of glass or plastic and is used to help heat swimming pools and other larger water supplies.

Another type of solar water heating panel is the integral collector storage system which is also called the ‘batch’ system by some. These systems use a glazed box instead of a plate and have at least one black tube or tank in it, through which the water passes to become heated. When the water passes through the tubes into the glazed box, it becomes heated by the sun’s rays so that the backup heater in the storage tank does not have to do much if any work.

The third type of solar water heating panels is the evacuated tube solar collector which is normally used in commercial settings rather than residential. In this type of collector, there are rows of glass tubes that have an outer and inner tube. The inner tube is made out of metal and is attached to a fin which has a coating on it to prevent heat loss.

Each of these types of solar water heating panels is used as the first stage of the water heating process since they utilize the sun’s rays to begin to heat the water, which is then pushed by various means into the storage tank to await use in the individual’s home or in a commercial setting.
