Filters form an important part of a photographer’s camera bag. It mainly comes in two shapes circular and rectangular shaped. It is usually made of glass or plastic. Filters made of glass offer better quality to the photographs when compared to the one made with plastic.

Some of the commonly used filters are:

1. Polariser Filter

2.UV Filter

3. ND Filter

Each one has got its own function. A polarizing filter is used to improve the color saturation in an image and also for removing the reflection from water bodies, when held at a particular angle. UV filter is mainly used for the protection of the front element of you lens. ND filters are used to cut out the extra light falling into your camera. ND filters come in many varieties.

If you don’t have the budget to invest in filters then you have to use the filters provided in your post processing tools like Photoshop. If you use filters from a post-processing tool then there will be some loss of quality in the image. This can be avoided if you use a physical filter screwed at the front end of your lens. Filters are mainly available for SLR lenses. Nowadays, you can also find filters for digital cameras.

N   Now, Following questions will come to your mind.

1. Which Filter Should I Buy?

Whether you have an SLR camera or a digital camera, I recommend buying a UV filter. This serves two purposes. Firstly, It protects the front element of your lens system. In case if you are not using one and accidentally if you camera falls down, then there is a chance that the front element of your lens system may get scratched or broken. So, you will have to repair/replace it, which is costly. So, better buy and fix a UV filter in front of your camera lens. This is a basic filter, whichall camera owners should have.

2. Is there Any size for the Filter?

There are two varieties of filters available in the market. Filters with fixed thread size and ones with rectangular disc and adapter. If you are using fixed thread size filters, then you will have to buy separate filters for each lens if the thread size of the lenses are different. This is the case for an SLR camera. For a normal digital camera, since the lens system is permanently attached to the camera body, you can use all types of filters for the given thread size, specified in the camera manual. For certain digital cameras, there won’t be any thread to fit in the filters. For such cameras, you can check on the Internet for any available filters and adapters.

3. Which Material type should I Choose?

As I told earlier, there are filters made of glass as well as plastic. So, which one to select? Plastic filters will introduce some distortions to your image. So, it is better to go for the glass ones. Plastic ones are cheap when compared to the glass filters.

4. Are there any Recommended Manufacturers?

Some of the well-known filter manufacturer companies include Hoya, Kenko and LEE. You can select your desired filters from them.
