Think sunglasses for your lenses. By removing reflections, you reveal the color, texture and detail beneath. So, leaves are greener, skies are bluer, and the beautiful rocks at the bottom of that secret mountain lake are revealed. CRPL’s are also great for removing reflections from car windows, and painted surfaces. Depending on the lighting conditions the effect can be dramatic or subtle but it never hurts to pop it on and give it a try. Circular polarizers are easy to use too. Once attached to your lens simply rotate the outer ring of the filter while looking through your viewfinder or screen until you achieve the right amount of reflection control. When the colors and detail look right, take the picture.
