Lens Depth Distortions

Telephoto

70mm 
  
- camera approx. 1 meter from stool

- Stool is not stretched

- Background is not distorted

-The with of the photo is a lot narrower then the WA lens.

-As for distance, with the telephoto the background is a lot closer to the object.

-For the telephoto, the object contracts and does not really enlarge.

Wide Angle

28mm

- camera approx. .4 meter from horse

- stool is obviously distorted & stretched

- Background is obviously distorted

-The with of this photo is a lot wider and we see a lot more of the background.

-For the background distance, it is a lot further with the wide angle

-For the wide angle, the object expands and enlarges a lot in the bottom

Telephoto

70mm

- camera approx. 1 meter from subject

- subject is not stretched

- Background is not distorted

-The with of the photo is a lot narrower then the WA lens.

-As for distance, with the telephoto the background is a lot closer to the subject then with the wide shot.

-For the telephoto, the subject  looks a lot more normal than the wide angle lens

Wide Angle

28mm

- camera approx. .4 meter from horse

- stool is obviously distorted & stretched

- Background is obviously distorted 

-The with of this photo is a lot wider and we see a lot more of the background.

-For the background distance, it is a lot further with the wide angle.

-For the wide angle, the subject gets distorted compare to the telephoto shots. 

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?

So for this scenario I would get a telephoto lens to shoot the subject so that the background would fill the frame and we would not se the edges of the backdrop
