There were 9 of us doing the Natural Portraiture one-day course with Michaela through Eastern Suburbs Community College. This feature image was using the diffused light coming in from an inner courtyard and we were taught how to use a grey card to assess our exposure.
The smaller images were using a stronger light, although still natural. The first one is inside but capturing light streaming in an east-facing window and using white cardboard to reflect this natural light back onto the subject: a natural fill light. The last two were taken outside using a reflector disk.
