- Little background

- About 6 meters away from subject

Wide angle: 17mm

- A lot of background on the sides

- More background

- About a meter away from subject

Telephoto : 55mm

- Little amount of background

- Subjects look close between them

- Flatness

- Body ratio distortion 

- about 2 meters away from subject

The Take Away 

          - what happens to the width of the background when you go from WA to tele?

WA : wide amount of background + distortion

Tele : small amount of background

          - what happens to the distance between the background  & subject "  "  "  " "  "  "?

WA : more distance between subject and background 

Tele : less distance between the subject and background

          - what happens to the subjects themselves in terms of expansion & contraction (for the width) as well as compaction and enlargement (for front to back)?

WA : body proportion distorted (close to camera : bigger / further away from camera : smaller)

Tele : body ratio respected 

  Scenario: 

go further away and use a telephoto lens
