Focal Length Lab

TELEPHOTO

75MM
Their shoulders seem a lot more broad
Their facial features are widened too
Camera approx. 4m from subjects
The subjects seem a lot closer to the background, distorting the distance in the image. Sean's (LEFT) ear has become more prominent in the photo.

WIDE
18MM
We can see past the seamless in the background.
Camera approx. 2 from subjects
There is a greater distance between the subjects and the background. Their bodies do not have any apparent distortion







TELEPHOTO
75MM
We cannot see past the seamless in the background
the legs of the chairs appear to be more compressed and closer together. There is not as much distance between the legs closest to the camera and the legs furthest from it.
Camera approx. 4m from subject


WIDE
18MM
We can see past the seamless in the background
There is a greater visual distance between the legs of the stool and the chair. The subjects do not seem as close to the background, we can see that there is some distance there. There is also more three dimensionality to the table because we can see it go back into the picture.
Camera approx. 4m from subject









 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?

ANSWER: You can move closer and reduce your focal length at the same time
