E-30 with Zuiko Digital ED14-35mm F2.0 SWD
35mm, f/4.0, 1/80s, ISO1000, -0.3ev
I tend to find f4.0 aperture on the E-system to be adequate for close-up portraits. The opening provides enough depth-of-field for both front and rear-focus range, to ensure the whole of the face is in focus while blurring the background.
The lighting was from a single window, with a light white curtain providing soft diffusion of the sunlight. The shadow effect provides depth of expression.
