Lab 4 : Lens Depth Distortion

Lens Depth Distortion

Telephoto

55 mm

- Camera approx. 3 meters away from the objects

- We can see on the picture that there is no distortion

- Everything looks more flat/compacted

Wide Angle

18 mm

- Camera approx. 1 meter away from the objects

- We can see that the objects on the table are distorted and stretched.
- The table, seamless, wall & ceiling also look a bit distorted
- We see too much of the background in the picture

Wide Angle

18 mm

- Camera approx. 1 meter away from the subjects

- We can see that the lockers go really farther behind (they look stretched)
- Subjects are distorted and they look as tall as the lockers

Telephoto

55 mm

- Camera approx. 4 meters away from the subjects

- Subjects look no longer distorted and stretched

- Lockers no longer go really far behind them

- Image looks flatter

  The Take Away ( i.e. what you learned from this)

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

It becomes more compacted, you're not gonna see as much things in your frame.

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

With the telephoto, the background seems to be closer to the subject and with the wide angle, it seems to be farther away.

          - what happens to the subjects themselves in terms of expansion & contraction (for

            the width) as well as compaction and enlargement (for front to back)?

The subjects become flatter and compressed.

When they are shot with the WA, they are distorted.

  Scenario: imagine that you're shooting a model (full body) against a seamless. Your

  framing of the model is what you want but the edges (and beyond) of the seamless are

  visible in your frame. You don't want to move the model back towards the seamless and  

  you don't want to have to retouch out the seamless edges. Applying what you learned

  from this exercise today, what's the solution using just your camera & lens? 

I would use the telephoto and then just back off till my subject fills my camera's frame.
