    Understanding Focal Length: Wideangle vs Telephoto

    Wide-angle and telephoto focal lengths each give pictures a very different look and feel. Here’s how to make the most of the extremes

     

    What is focal length: adding depth

    20mm

    Adding depth
    A wide-angle lens (above) exaggerates perspective, making the foreground 
and background appear further apart.

    What is focal length: adding depth

    85mm

    A telephoto lens (above) appears to flatten the image, bringing the key elements closer together. Notice that the tree in the foreground is the same size in each shot.

     

    What is focal length: cleaning up the frame

    Cleaning up the frame
    Because long lenses have a narrower angle of view, it’s easier to keep distracting elements out of the picture and create ‘tighter’ shots. Wide-angle lenses take in a much greater expanse, meaning you have 
to check the edges of the frame closely for unwanted elements.

     

    What is focal length: controlling distortion

    Wide-angle

    Controlling distortion
    Used at close range, a wide-angle lens (above) creates a distorted image, which can make portraits look like caricatures.

    What is focal length: controlling distortion

    Shot at a longer focal length

    For more flattering results, stand further away from your subject and zoom in with a longer focal length (above). The narrower view isolates a cleaner background too.
