Hard Light:
(4th picture in the list) I love the moment in this photo and the boy's face. I really like how the light is used to highlight his figure and enhance the color.

Soft Light:
I love this picture! I really like how the light is soft enough so that you can see the reflections in the eyes of the seals. The color is enriched by the type of light, especially the seal's pink mouth, and because nothing is too bright you notice the penguins in the background and the other birds in the sky. I totally love the moment here, too.

Diffused Light:
I love the color in this picture and how it all leads the eye directly to the forcus of the picture. The diffused light really enhances the drama of the picture as well.
