Lab 4 - Lens Depth Distortion

Telephoto

105mm

- Camera approx. 5 meter from the table

- Subjects ears are more pronounced

- Main table and wall distortion is eliminated

- Bag and table look realistic in size but small compared to the WA shot

Wide Angle
24mm

- Camera approx. 1 meters from table

- WA type of distortion can be seen on the table, making it look wider and the bag is also slightly distorted(Looks slightly bigger compared to Telephoto)

- Subject looks slightly smaller

- Table looks almost square because of distortion




Telephoto
105mm

- Camera approx. 5 meter from the subjects

- Subjects ears are more pronounced

- Subjects body are proportionate

- Stool looks slightly bigger









Wide Angle
24mm

 - Camera approx. 1 meters from table

- The background can be fully seen(Seamless is not taking up the whole background)

- Subjects body look slightly longer(Especially the middle subject)

- Stool looks more realistically sized compared to the telephoto shot



 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?

• The background is almost completly covered by the seamless when shooting with the Telephoto compared to the WA lens which the viewer can see more of the background.

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

• The subjects seem a lot closer to the background when shooting with the Telephoto lens compared to the WA lens which shows almost the exact distance the subjects were from the 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)?

• For the WA lens, the subjects bodies are slightly longer and wider compared to the Telephoto. The background is made smaller with the Telephoto lens and seems closer to the subjects compared to the WA lens which gives an almost exact distance of the background to the subjects.

  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?

• Step back a couple of meters and use a Telephoto lens to take the shot but keep about the same settings in your camera. The subject will stay somewhat the same but the background will be a lot smaller and the edges of the seamless shouldn't show.
