Focal Length of a Lens

In this lab, we test the length of the focal lens. With my camera the mininum is 18mm and its the widest, so we can capture everything but if you want to focus only on the face, you use the telephoto lens (55mm for my camera). 

in  the first picture our subject is doing a kick. for this one i used the 55mm lens. as we can see, her front leg looks a lot bigger than the rest of her body. 

 with this one i used the wide angle lens (18mm). we can see that her whole body is normal size.

here i used the telephoto lens (55 mm). same effect as the first picture but different body part. Her hands look much bigger, even as big as her head.

In this one I used the 18 mm lens (wide angle). We can see everything clearly and the camera is not only focused on the hands but on the whole body.

For this one used the wide lens (18mm). the camera is focused not only on her face but on  everything else.

For this one, i used the 55 mm lens. Her face looks more appealing.
