I believe that blogging has changed how we view the progression of our educational milestones. Books, as we knew them, documented our personal explorations spread over an extended period of time and are then compressed between the front and back covers. When recalling a sequence of events that lead to that light bulb moment, it is easy to skip the inevitable trials and errors and go straight to the epiphany. On the other hand, a blog entry is often created in the moment of inspiration, and can be revised quickly and with relative ease. As a result, my blog, like my life, is subject to change as today's ideas and beliefs transform themselves into tomorrow's axioms and facts.
My photographic experiments often include lighting faces that are wearing glasses. This is particularly convenient, since I've been a qualified model since the mid 1950's. In a nutshell, butterfly lighting works well in this situation. By keeping the Key Light (the one that casts the shadow) and the fill light (the one that puts detail into the shadows) well off the axis, there is less light to reflect back from the center of your subject's eyeglasses. You may see the hint of glare at the top edge of my glasses, but this blends in with my eyelids and is therefore less noticeable. Keep in mind that this glare is actually the reflection of the ceiling, illuminated by my on-camera bounce.

Post Script: The flash tube in the right image IS correctly covered. The bright portion that you see to the left of the gaffer tape blinder is decorative, and not part of the flash tube.
Big Catchlights: In an earlier post, I used some Tupperware and a cookie sheet to bounce light on to a hardwood floor. Looking back, it would have been faster to simple place the SB-30 on the ground facing the subject, and placing a Zumbrella, or similar shoot-through umbrella, between it and my subject's face. I still get the low angle necessary to eliminate glasses-glare and a much larger light source, but gain a measure of speed and simplicity in the setup.
Reminder To Self: This technique only works for head shots, since the full and three-quarter length portraits will result in overexposure below your subject's waist.
My father had always told me to avoid multiple catchlights. This stands for reason: In a natural environment, there should be only one light source: The Sun. This portrait reflects this philosophy, as only a single catchlight can be seen in each eye. I continue to follow his advice, and will consider this "light under an umbrella" a useful technique for providing both catchlights and shadow detail, especially when my subjects are wearing glasses.
