When it comes to taking pictures you will come across different names such as full length pictures, portrait pictures etc. What will determine the quality of your portrait is the kind of lens that you choose to use. In the following paragraphs I will mention a few things to think about when taking a portrait photo.

The type of lens that you choose will also depend on the environment at that particular time that is light conditions, wind etc. You need think about the focal length. The focal length is affected by the size of the film you are using. From personal observation I have noticed that a portrait with 35mm film camera is best taken with a 105m lens and an 80mm requires a 160mm lens. You can see then how the size of the film has an effect on the lens that you choose and the eventual picture that you take.

If you are unsure as to how to make these adjustments in focal length, size of lens and film you can always ask around from fellow photographers who understand the concept better . Sometimes having a practical experience provides a better explanation than theory.

The view of a picture is dependant on how near you are to the subject and not the size of the lens. Basically the size of the lens will not affect the view it will stay the same. The number of objects that appear in the picture is what will change. This is assuming of course you are taking pictures from exactly the same point without changing anything except focal length.

Like I said before to fully appreciate the effect a lens has on a portrait picture would be best understood in a practical set up by experimenting with different size lens until you have grasped the concept well.You will be able to find some great DSLR cameras and lenses at any one of these:
