Focal Point

The focal point is the part of the photo the eye is most drawn too, the following link will take you to a website that describes the use of focal point in photography: http://www.worldstart.com/using-focal-points-in-photography/

This photo uses a shallow depth of field, making the raindrop sharp, and drawing attention to it, therefore making it the focal point.

The next photo uses leading lines, this is when objects in the photo draw lines towads the subject or focal point.

Depth of Field

Depth of Field is an important factor in photography, the following link will take you to a website that describes depth of field in quite complex language: http://www.cambridgeincolour.com/tutorials/depth-of-field.htm this is good because it helps you understand how it works and how to use it.

This photo is a good example of a shallow depth of field because the objects in the foreground are sharp and the background is out of focus, it was taken by Tedric Garrison. Furthermore the following photo has a large depth of field because everything as far as you can see is in focus.
