Well, the lower the number the wider field of view and the higher the number, the narrower the field. This is customarily referred to as "zoom". When you are using a wide angle focal length, you are capturing a wide area of view that extends like a cone from the lens. This is helpful if you are up close to something big, or if you are wanting to exaggerate a foreground element.
A normal focal length would be in the area of 50mm. This is considered the closest to what we see with our eyes. The relationships between objects is familiar when you are in the normal range.
On the longer end of the spectrum, you will find the telephoto focal lengths. This is where you reach out and touch something. You get optically closer to the subject, and you also compress the background. Background opbjects will appear larger in relation to foreground elements compared to how they appear with your eyes.
I will probably be doing a tips and tricks on this ery topic in the next couple of weeks. If you subscribe to my journal Photo Trek (http://phototrek.446Photography.com) you will be made aware of when I do this tutorial.
