A look at filters.
There are a different kinds of filters out there for your lenses and all have different qualities and do different things.
Starting off with the UV filter, the UV filter will absorb ultra-violet rays but is more commonly used as a lens protector. This can come in handy if you have an accident and drop your equipment the filter might break but your lens will be protected from certain impacts.
The circular polarizing filter is great for doing outdoor shots, for example when shooting scenes with sky it will help increase contrast between the blue of the sky and the white of the cloud. It can also get rid of unwanted reflections in windows, glasses etc.
Neutral Density (or ND) filters reduce the amount of light coming through your lens so you may select a wider aperture, this is great for taking portraits because it will reduce the depth of field and have a nice focus on your subject.
There are still many other kinds of filters that can be used to all kinds of creative ideas so if you're looking for something new to try there are plenty of choices. The vary in price, from $27.99, to our most expensive which is $250.
