I took these headshots of Marta Prachar awhile back, but I've just recently gotten around to updating this blog.
Marta was one of the first clients I had where I experimented with some different natural lighting techniques. Originally I was using mostly studio flash with very limited natural light, but after looking at a ton of headshot portfolios and listening to my client feedback, I've decided to change my approach.
One thing you'll notice immediately with natural light shots that you won't get with flash is the large iris and small pupil. A sudden flash doesn't give the eye enough time to react to the sudden burst of light, so the shot records and open pupil. Continuous light, in this case natural window light, gives the pupil time to contract. If one of my clients has anything but a brown/black eyes, the pupil contracts and the iris expands and catches all the light, which gives the eye a lot more color. Depending on the light setup and pose, a reflection of the light source can mask the small amount of pupil that's visible, giving the effect that the eye is more or less one solid color.
