Focal+Length3

__ **Explanation of Concept ** __

Focal length is how far away the lens is from the cameras sensor. You can shoot from many different angles including wide angles which is used a lot when taking pictures of landscape or medium telephoto which is commonly used for taking portraits. If you want to have a main spot in the picture that you want to stand out the lens will be far from the sensor so you will zoom in.
