Details - Objects, Pinhole camera:

Photographing objects or details of objects shows me some important characterizations of the pinhole camera. 

The pinhole has a very wide angle view which allows us to come very close to the subject thereby deforming lines and shapes. 

The depth of field is infinite because there is no lens (glass), so both details which are very close and far away are evenly sharp. That characteristic gives us the impression that a small object which is near the pinhole looks huge and without proportion compared to a subject which is in the background. 

For example, a small toy car can look like a real car parked in front of a real house which is in the background of the image.
