Understanding Circular Polarizers: Enhance Your Photography with Creative Control

Circular polarizers are essential tools for photographers, enhancing images by managing reflections and boosting color saturation. They help brighten or darken skies, reduce glare from water and glass, and enhance detail in flora. While they offer artistic control and the ability to salvage subpar shots, using a polarizer comes with trade-offs, such as decreased exposure and limitations on lens specifications. Learn how to effectively mount and utilize these filters to maximize your photography while embracing the nuances of polarizing effects.

Presentation Transcript

  1. Circular Polarizers An explanation of what they do, why you should use one, what you gain and lose in the process, and how to handle them.

  2. What do they do? • Brighten or darken the sky in your images • Decrease reflection intensity on glass and water surfaces (but not on metal) • Enhance color saturation on flora

  3. Why should you use one? • To enhance the impact of images • To increase color saturation • To make white clouds stand out against a blue sky • To intensify rainbows! • To see below the water’s surface

  4. What do you gain? • Artistic/creative control • Increased contrast in the image • Ability to salvage a bad image • See what the human eye can’t • You will develop an understanding of and appreciation for reflections

  5. What do you lose? • 1.5 – 2.0 f/stops of exposure, due to the darkening effect of the polarizer • Forces slower shutter speeds, or larger aperture settings • Can’t use lens wider than 28mm • Can’t be used for panoramic shots, due to inconsistent sky darkness

  6. Mounted on SLR lens or handheld loosely • Can be mounted on the front of interchangeable lenses • Can be handheld in front of the lens on point & shoot cameras
