Lens Filters





I got some of my new lens filters delivered today, when I was playing around with them a cool bird flew past. Yh, he was cool and made the photograph more cool as well.




A little bit about the lens filters

A lens filter is a glass/plastic circle which you place on your lens, it gives you more control over your photography as well as protecting your lens.
There are different types of them which give different effects. The most common ones are :


UV (Ultraviolet) Filter

It is mainly used to protect the lens from damage, it also absorbs the ultraviolet rays and reduces haze.



Polarizing Filter

It basically selects which light rays enter your lens, as the light rays that are reflected by any surface become polarised. Therefore it removes reflections from surfaces such as water and glass, as well as making the colours a bit more saturated and clearer; having a better contrast.



ND (Graduated Neutral Density) Filter


This one allows your image look more neutral and have an equal reduction in light, it also reduces overexposure if long exposure time is used.
