Default Which filter should I buy

Dear friends,
I am presently using Canon 1000D. Using 18-55 mm lens supplied as kit. Now I have purchased one 55-250 mm Tele zoom also. I am interested in Landscape and Potrait photography, which filter should I but Neutral Density or CPL? Please advice. Thanks.

Three types of filters can be useful for landscapes, less so for portraits:

* CPL (Circular Polarizer) will reduce glare and reflections, and increase sky contrast.
* ND (Neutral Density) filters allow slower shutter speeds with wide apertures, or long-duration photos, as of moving water.
* GND (Graduated ND) filters are half-clear, half-dark, for shooting scenes with split brightness, such as a darker landscape under a brighter sky.

A CPL *could* be useful in portraits shot in uncontrolled conditions. A GND *could* be used for special portrait effects. But all these filters are more used for landscapes etc. Two CPL's together effectively make a variable ND filter.

What are you trying to do that you can't without a filter?

If you don't know which filter you need, you probably
don't need a filter at all.

A CPL filter can be useful for some landscape shots.

This was taken with a CPL filter. The filter reduces
glare on the sunny side (left) of the sculpture and
adds 'drama' to the sky.


A ND filter is a bit more specialised. Unless you
have a specific need for one, you probably don't
need it.
http://en.wikipedia.org/wiki/Neutral_density_filter

This was taken with a ND8 filter. The long exposure
needed to compensate for the dark filter gives a
very blurred appearance to the moving water.

If you buy a filter, make it a good one.

A cheap filter can degrade image quality in a lot of minor ways, and a few major ways.
