Camera Lens
Light travels in waves. When light strikes an object it is modified by the object. Light is absorbed by dark objects and reflected by objects like water, glass or rocks. To eliminate unwanted reflections in specular highlights, photographers use a filter on their camera lenses called a polarizing filter. This filter will allow you to control unwanted reflections from glass or water in your photographs. It can also be used to deepen the color of the sky or increase the differences between a cloud and the sky. It will remove glare from most views, but will have little impact on metal objects, which reflect mostly non-polarized light. The following are ways to use a polarizing filter with your camera lens.
Instructions
1. Screw the filter on to the front of the camera lens as you would any filter. You will notice this filter is different than most filters. It has an adjustment rim on the front of the filter. View your subject through the camera. In single lens reflect cameras you will be able to see the changes in the view finder immediately.
2. Take a number of exposures adjusting the filter between each exposure. This will allow you to view prints or see screen images to determine the impact of the filter.
3. Notice the change in sky and the appearance of the rocks. Try taking pictures through a window and use the filter to minimize the glass reflections.
