Here are 3 Filters that you may want to consider adding to your photography equipment.
Damage to your camera’s lens could cost you many hundreds of dollars to replace, purchasing any or all 3 of the following filters at a fraction of the cost of a replacement lens might be worthwhile considering.
CPL Filter (Circular Polarising Filter)
This polarising effect is most effective when used to increase the contrast and saturation in blue skies and make clouds stand out.
A polarizing filter removes unwanted reflections from non-metallic surfaces such as water, glass, snow etc. They also enable colours to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. Polarizing filters do not affect the overall colour balance of a shot.
A circular polarizer filter (CPL) is generally required if you want to use the "auto-focus" feature in your camera.
These filters can also be used for video & digital cameras.
UV stands for Ultraviolet, which is light that is invisible to the human eye. UV filters were used to cut down on haziness, such as in mountains and around coastal areas, but the digital sensor isn’t as sensitive to this as 35mm film was. These days UV filters are used, mainly as aprotection for your cameras lens.
Having a UV filter attached to the lens at all times protects the lens from scratches, dust, and weather. There are debates among photographers about the use of UV filters; some argue that they visually affect the outcome of the photograph while others argue that they don’t affect it at all and that the filter is great insurance.
I use a UV filter screwed onto my lenses; and have had one of my lenses saved thanks to the attached filter. However, if you are going to use a UV filter, don’t buy the cheapest one you can find.
Skylight 1A Filter
A filter which is used in front of the lens in order to filter out UV light that can cause a bluish haze. A skylight filter is also coloured slightly pink (or yellow) in order to give pictures a warmer appearance. In the digital age these filters are used less than before, since colour temperature can be influenced in-camera and in processing, especially when using the RAW file format.
