Filters
A necessary item which most photographers must have to ensure correct amount and right rays of sunlight enters the camera into the exposures.
Just to state the commonly used filters, they are as follows: Linear Polarizer (PL) or Circular Polarizer (CPL) The light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camera lens. PL (Linear Polarising) and PL-CIR (Circular Polarising) filters have the same effect, but it is important that you choose the correct version for your camera. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors 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. Skylight It reduces the excess bluishness that frequently occurs in outdoor color photography, especially in open shades under a clear, blue sky. The absorption peak is in the range which corresponds to the film's green spectrum. This means outstanding outdoor shots with superb color balance and clarity under all conditions. Also keeps skin tones free of colored reflections from nearby objects such as the shade of trees. Ultraviolet (UV) It absorbs the ultraviolet rays which often makes outdoor photographs blurry and hard to see. A multi-purpose fine-weather filter all films being it colored or black and white. Also serves as a permanent lens protector.
