Portrait

The first photo is a portrait shot from the waist up. The model is looking natural (because I made her laugh).
The picture below is a closer shot of just her shoulders and her head which is posed.

Here is a close-up shot of her tongue stud which is an interesting feature to pick out because it is metallic and contrasts her natural skin.

Depth of Field

These are some basic shots experimenting with depth of field. The objects are purposefully laid out to emphasise the differences in focus.

Here I have used crayons to experiment with the depth of the photos. I particularlylike the second one as it is a clear shot which is composed well.
