General Circular Polarizing Filter Information
The concept of circular polarization is similar to that to linear polarization. Circular polarization is a combination of two perpendicular linear waves that are 90 degrees out of phase with each other.
As any light wave can be represented as a sum of two linearly polarized waves, it also can be sought of as a sum of two circularly polarized waves, one rotating clockwise and another – counterclockwise. In physics, the circular polarizing filter is a device which when illuminated by wave containing both clockwise and counterclockwise components, would pass only one of them.
The ‘circular polarizer’ term when applied to filters used with modern photo cameras is misleading, because it does not do what is described above, namely, allowing to pass only one circular polarization. Which is good, because it is not what is required in this case. The circularly polarizing filter in photography consists of two components: first light passes though a regular linearly polarizing filter which allows only one linear polarization to pass and blocks another, and then light goes through a second component – a quarter wave plate which converts the linearly polarized light into a circularly polarized.
The first component allows to block or highly reduce light scattered from a sky at 90 deg. and reflections from shiny surfaces such as glass or water. The second component is needed for most of the modern cameras to work with the resulting light correctly. If your camera uses beam-splitter reflecting all or part of light at 90 deg. into auto-focusing device and into an exposure-metering system (e.g. if you have am SLR or DSLR camera), then it utilizes only one linear polarization out of incoming light. Both systems are designed to work with light which is not linearly polarized. However, if we place a linear polarizer in front of a camera, this light might be totally blocked by 90-deg reflection, and both exposure meter and auto focus will not work properly. So, to make the camera work after passing the light through a linear polarizer, we need to convert this light into a state which contains both linear polarizations in equal amounts. This is done with the use of a quarter-wave plate, which produces a circular polarized beam, which allows your SLR camera to function properly.

Looking after your camera
Use a Camera Bag
A camera bag does more than just protect the camera against scratches and dust: It keeps it safe from rain because many are waterproof on the outside.
Be Very Careful Around the LCD Screen and Camera Lens
Use only special equipment to clean your camera’s LCD screen and camera lens. Buy a special cleaning kit that includes liquid solutions, microfiber cloths and brushes that have been specially designed to clean your camera lens.
Never Leave Your Batteries in Your Camera for Too Long
Many camera batteries are now alkaline or lithium formats. If you keep your camera with the batteries inside of it in a moist area, then the batteries can get corrosive. So if you’re thinking about just putting your camera on the shelf for several months, do yourself a favor and remove them.
Turn Your Camera Off Prior to Doing Anything
Before you do anything to your camera, always keep in mind that it should be turned off first. No matter what it is—swapping lenses, changing memory cards or disconnecting or attaching cables—your camera should be turned off.
Cold and Wet Weather Can Wreak Havoc on Your Camera Body
Take your camera out only in a waterproof bag. If the weather’s unusually cold, just wrap your camera in a plastic bag that has silica desiccant packets for the reduction of moisture. It’s also a smart idea to have a soft towel with you to wipe off any moisture, just in case it should get on your camera.
Good Memory Card Care Is Good Camera Care
Only transport your memory cards inside of a protective caseMake sure the memory cards stay dust-free at all times. When removing memory cards, make sure you do so indoors or in non-dusty situations.
Make sure that you keep memory cards only in cool places. Never keep them in places where they may heat up, like dashboards or glove compartments.
Never place your memory cards close to magnetic sources. Examples of magnetic sources are things such as audio speakers, TV monitors and actual magnets.
Use a Filter to Protect Your Camera Lens
The lens of your camera is naturally fragile. As such, it’s susceptible to scratches, cracks, dents…you name it. A UV filter will not only will you give your lens a fighting chance, but you’ll also enhance the quality of your pictures.
Condensation Can Be Controlled
Condensation normally happens when you move your camera between different temperatures.
Allow your camera a chance to naturally get used to the hotter environment. Don’t place it inside a closed plastic bag when transporting it between different temperatures! Just let the camera sit in the humid temperature for a while, until condensation disappears.
If this still doesn’t get rid of all of it, you can utilize a soft cloth to wipe away any remaining moisture and marks left behind from the condensation.
