A polarizer might be the most versatile filter around, and it's value extends well beyond deepening a blue sky. In fact, a key polarizer function in the digital age is to minimize the glare on reflective surfaces so that the natural color is revealed. This filter should be in every outdoor photographer's camera bag or photo pack!
It is amazing to watch the evolution of surveillance gadgets that modern technology brings us. Hidden cameras are now tucked away inconspicuously in smoke detectors, motion detectors, stuffed animals, clocks, and countless other innocuous products.
Today, it’s easy for manufacturers to squeeze a great deal of functionality into a tiny package. Integrated circuits have millions of transistors packed onto tiny chips, wristwatches offer a thousand functions, and cell phones can access the Internet and capture still and video images. Of course, those tiny integrated circuits enable the manufacture of most of these devices in the first place.
Until the early 90s photography and computing managed to work together using a scanner to digitize prints. My first electronic still camera, the Canon Xapshot (left), wasn’t digital but it did record 50 images to a 2-inch disk.
