Compostion / Depth of Field

This post will show how the eye works looking at an image.

Composition
Same subject in the shot but viewed from different angles.

wikipedia:'composition is the placement or arrangement of visual elements or ingredients in a work of art, as distinct from the subject of a work. It can also be thought of as the organization of the elements of art according to the principles of art .'

It makes your eyes follow

This is very much like reading panels in comic books

The image is gold+dredge+3. I was given this image as well as many others by Dan.

I have high lighted where the eye follows the light around the image, starting from the lightest part around to the darker edges.

Depth of field

wikipedia: in optics, particularly as it relates to film and photography, depth of field (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.

The best way I can describe this is the way your eye focuses on certain objects in contrast to the background which can be out of focus to the viewer.
