As intended, the Year of Square exercise motivates me to make pictures every day, and re-habituates me to pay attention to light. Seeing that the full-screen, blank browser page on my computer presented a comparatively large, reasonably bright light source, I snapped this self-portrait using the built-in iMac camera. This shows me an angle for lighting hats that would not have occurred to me otherwise. In effect, the screen is a big, rectangular, soft light source directly below the lens axis (See how the shadows are above the lit portions of the hat?). I’m glad I made this sketch with the camera at hand, as it gives me ideas for other portraits.
