What is Depth of Field?

Again, i think it is a good idea for me to create a simple understanding of each element of photography. Next on the list is Depth of field. It makes a lot more sense now. Below is simple copy and paste info to show that I have researched the function and I will shortly show images below of my own.

Depth of field is the amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph. A preferred selection Depth of field ("DOF") in a focused subject in an image can be quite subjective. Remember this, adequate selection of DOF for one situation, application may be unacceptable for another photographer. It is all a matter of personal preference when trying to determine the appropriate use of DOF to enhance an effect in a photograph.

You have to recognize the eventual effect of depth of field control that can bring to your photo but HOW TO ?? Simple, read on and digest.

In simpler term, we define depth of field as the zone of sharpest focus in front of, behind, and around the subject on which, when lens is focused on a specific subject; with TTL (through the lens) SLR camera, DOF can be previewed in the viewfinder of a camera - the preview is very handy for critical type of work. For an example, when taking a product shot, when you require absolute certain if DOF is adequate to cover the object you intend to photograph Generally, the closer the subject to the camera, the more evenly with the distribution of depth of field in front and behind the subject. As distance of focus extends, DOF usually will be more behind than in front of the focused area.

To help me out, I will experiment with some test images later on my blog (I used the blog with the penguin images). Within this blog I demonstrated with both shallow and deeper depth of fields.
