Because we need to send in 8 photos in total, I though it would be nice to show all effects with artificial light as well as natural light. The same principles of the angle of light, rate of diffusion and hardness apply. But since the light source is all the same, I had to think of when and how to make best use of it. So first of all, shape.
As I had found out with the exercises on artificial light, the shape is best seen when the subject is lit from the back, preferably with hard light. So I thought it would be a good idea to take a photo at noon on the roof of our balcony and show the harsh shadows that are formed at that time of the day. We're very close to the equator, so the shadows are really right under the chair.
I thought I'd give it a try indoors, because even thought the shadows give a good reflection of the form, I think there's too much distraction because of the tiles of the floor and the colour of the chair. We have a big staircase in our house with windows on the bottom and the top of wall that faces the staircase. The light shines through blue/greenish glass, giving a nice light. I thought if I'd place the chair in front of this light, it would show the form in a nice way. Here are some of my trials:
I wanted to find the best way to show the form of the chair, but also depict the feeling that the light from the windows bring to the atmosphere of the staircase. I decided that I didn't want to show the windows directly, to keep the light subtle and also realized after taking the last photo that I wanted to add some of the opening in the wall to balance the chair.
My final choice shows the subtlety of the light coming from below and above and therefor really emphasizing the form of the chair. The window brings a nice balance to the chair and I thought the light switch fits nicely in the theme of the assignment. i will not change the colour balance of this image, because I really like the blue/greenish feel that it has to it, and the colour of the subject is not of importance anyway.
