Lens Depth Distortion

      Wide Angle 

• 18 mm (28 mm equivalent) 2-3 meters from the people 
• Lockers are stretched and give an allusion of leading to somewhere
• Distortion of the floor, lockers and background.  
• Subjects are taller from the distortion.

    Telephoto

• 55 mm (80 mm equivalent) 2-3 meters from the people
• Lockers are compressed.
• Less distortion of the floor, lockers and background.  
• The subjects seem smaller from the lack of distortion.  

Wide Angle

• 18 mm (28 mm equivalent) 2 meters from the object
• The background is far from the object and the space behind the object is wide and spacious.  
• Distortion of the floor, object and background.  
• Objects are bigger, taller and more stretched.  

Telephoto

• 55 mm (80 mm equivalent) 2 meters from the object
• Background and objects are close and compressed. 
• Less distortion from the background, floor and objects.  
• Objects are smaller and compressed.  

When you go from a wide angle lens to a telephoto lens, the width of the background is smaller and has less distance.  It also comes closer to the object which creates a compression and a lack of distance.  When the subject is expanded and enlarged, it looks taller and longer.  An object that's contracted and compacted looks smaller.
