This exercise was aimed at showing the difference in shadow and light when you move a diffused light around a subject.
The diffusion material used must be larger than the subject.
I chose to photograph a person. The plain background is a white wall behind the subject. The only limitation I really suffered was a lack of space. There is some natural light in the room however without any studio lighting the subject would appear dark.
In this image I have placed the light behind the subject and as happens often when we photograph a subject into the sun we see the silhouette, the shape however not the features or texture of our subject.
With this shot I have placed the light directly in front of the subject. It gives a kind of cut out cardboard effect. There is no sense of the three dimensionality of our subject. The light does not give too much texture however more than if we back lit the subject.
Side light has given us a much better sense of texture and dimension. One side of our subject is illuminated and the other in shadow and would need some fill. However I can see texture the lines on the face the details of the eyes much better and the shape of a head is evident.
Backlit and to one side gives us a sense of dimension and form on one side however the side in shade still appears flat. This effect could be used for certain subjects to create a type of highlight behind the hair and then some fill on the other side.
In this image the light is directly above the subject. This has created unwanted shadows under the neck and eyes. It leaves us without too much detail of the texture of the face. By the subject inclining his head I have managed to have a good light on the forefront and nose.
This light is above and slightly to the right. To me there seems to be a sense of dimension however there is too much shadow still on the subject. There is a lack of texture.
Here the light is above and to the front.
Here the subject is well lit. We lose some sense of texture and depth but overall we have some shadow and texture which give us the sense of a persons face with shape and texture. It is slightly more flattering some lines are removed without appearing false. This is my favourite I Can see some shadow which gives me a sense of depth. There is some texture in the beard and the lines of the face. The nose we can see some three dimensional effect. The eyes are lit well. There is shadow under the chin however it is not completely obscured.
This is an improvement on having the light directly behind or directly above to the right. There is a better sense of dimension and a sense of texture on the right side of the subject. It is something that could be used for a particular style of image perhaps if we wanted one side of the face to be obscured and still give a sense of dimension and texture. In this image I can see a good sense of three dimensionality.
