The different filters used in Photography are :

1)Skylight filter : This filter is used for protecting the front element of your lens from damage or dirt. A skylight or ultraviolet filter is mainly used to protect the front of your lens from dirt, dust or water. All you need to do is keep the filter attached to your lens whenever you are using the camera. This is particularly important when shooting in wet, muddy or dusty conditions.UV and skylight filters also filter out some ultraviolet light, which has the effect of reducing haze. Unlike a UV filter, a skylight filter has a very subtle pink cast to it.

2)Polarising filter : This filter is used for increasing colour saturation and reducing reflections in non-metallic objects. Polarising filters come in a rotating mount, as their effect varies as you turn the filter. So, once you've attached the polariser, and framed your shot, you need to slowly rotate the filter while watching the effect through the viewfinder or in Live View. The filter will also increase the colour saturation, and darken blue skies, giving greater contrast between any sky and clouds.

3)Straight neutral density filter : This filter is used to allow you to use longer shutter speeds or wider apertures. A straight neutral density, or ND, filter is essentially a 'darkened' sheet of glass or resin that reduces the amount if light entering a lens, and therefore reaching the sensor.

4)Graduated neutral density filter : This filter is used to balancing the exposure between a bright sky and a darker foreground, particularly in landscapes and sunrise/sunset shots. ND grads come in several different strengths, and with different transitions between the dark and clear areas.

5)Variable or strong neutral density filter : This filter is used to extremely long shutter speeds or very shallow depth-of-field effects in bright conditions. A variable ND filter is similar to a straight ND filter, but as the name suggests, with a variable filter you can vary the strength or 'density' of the filter by rotating the filter elements. using a variable ND filter at the higher strengths are the same as using a strong plain ND filter, you use them in slightly different ways.
