There are three types of filters to consider. The most important one is the polarizing filter, or the PL filter. This gives control over reflections from glass, water, other shiny and semi- reflective (but not as reflective as a mirror) surfaces, as well as from light scattered from the sky. And then there are neutralContinue reading “Do We Need Filters Anymore?”

These close-up lenses are often called diopters, or plus diopters, because their strength isContinue reading “How to Get Very High Magnification”

Many problems can be found in the design of wide-angle lenses with large apertures. First of all are aberrations. Distortion is common, and correcting and editing images becomes more and more difficult as the focal length decreases. So how do lens designers make a lens that will not distort a image nearly as much inContinue reading “Wide-Angle Lenses, Fisheye Lenses, and Panoramas”
