Photoshop Elements 3 – Filters Many photographers with SLR cameras (digital or film) attach filters, such as the one shown at the right, to the front of their lenses to protect them from dust and scratches. Probably the most commonly used filter for this purpose is the 1A Skylight filter, a warming filter that corrects for bluish light quality of open shade and also absorbs ultra violet rays without affecting exposure. Camera filters also are available for a variety of special effects – a polarizing filter to reduce glare or increase color saturation and contrast, neutral density filters to reduce the intensity of light on bright days, diffusion filters to soften a photo and reduce wrinkles in faces, fog filters to simulate the effects of fog, and many more. Photoshop Elements filters are based on traditional camera filters, but go much farther. You can produce some amazing effects with these filters, which we will explore in this lesson.
