In order to experiment with natural lighting during the portrait project, I used an open window to produce the lighting for a photo-shoot. The following images show examples of subjects faces being illuminated with the use of just natural lighting from a window.
The above 2 images simply use natural lighting, and nothing else. the use of natural lighting in this instance allows for a soft illumination of the subjects face, allowing shadows to be cast across the face, but without them being too sharp or dark. This produces a more natural image, and allows the subject to be portrayed as they naturally are in reality.
For the above 2 images, I experimented with changing the background color of the image. This was done using a large black piece of card. I feel like this draws more attention to the face of the subject, and defined the shapes of the subject, separating them more from the background. I feel like the addition of a black background allows for the photograph to be given more dimensions, and feel more 3D.
Overall, the use of natural lighting in photography was a success, as I was able to create images that show the drastic contrasts between natural and studio lighting. Although natural lighting creates a more natural, soft light that portrays the subject in an (often) more flattering way, the lack of control that comes with using natural lighting can cause lighting issues (e.g the above 3 images are slightly darker, as they were taken when the sky was more overcast, thus the light was blocked.)
