Filters have two different meanings depending on how long you have had photography as a hobby.  Most of us today think as filters as an option with Photoshop.  This is not the case.  Before the invention of computers and things like Photoshop we had small glass discs to create the filtered affect.  There are many options with filters you can blur a picture, sharpen the picture, and even block out the UV rays.  Filters are often used to correct a problem or make a picture look a little different.

Lets talk about filters that blur a photograph.  When you are taking a picture of a waterfall at the bottom where the water rises in a cloud you can add a filter to create the cloud in the picture.  Cameras don’t always see what the eye sees.  In some cases it can have a high resolution to depict the actual water drops rather than the cloud, so adding a filter to your lens can help create the effect your eye sees.
