The Secret of Lenses by Lou Jones Famous portrait photographer Yousuf Karsh once quipped, “Look and think before opening the shutter. The heart and mind are the true lens of the camera.” To that point, our talent and energy create good photographs. And while the camera is the repository of details and data, lenses actually shape the way those images look. Choosing a camera is technical, utilitarian and economic. Choosing the right lens is art. As our tools grow more sophisticated, it is easier for us to fashion more interesting photographs. The differences between amateur point and shoot, prosumer, mirrorless, cell phones and DSLRs cameras are constantly being reduced, but lens choices are ever expanding: autofocus, vibration reduction, variable aperture, etc. Besides improving our capabilities, lenses have character and personality. You change lenses for simple reasons. If you want to see more, you mount a wide angle lens. The “glass” actually captures more than you can see with your naked eye. If you are trying to shoot a friend on the opposite ledge of the Grand Canyon and you cannot approach closer, you need a telephoto. It produces a much narrower angle than your eyes. In practice using depth-of-field can dramatically alter the appearance of an image. A wide aperture can be employed to throw a distracting background out of focus and enhance a delicate portrait. While a small aperture will put everybody in focus for a big group photo. Your eyes can’t do that. Artistically, different focal lengths have unique looks. Here I will share the secret lore that is never revealed: lenses “see” differently, i.e. they have personalities. And with a trained eye that character can be exploited by your imagination, to your benefit. 8 | PicsArt Monthly
