form

Form used in photography.

In all of these images there is a shadow, therefore all the photographs must have objects in them that are 3D in order for a shadow to form.

In this image you can see a clear outline of a airplane that is made from the light of the sun and reflected as a shadow onto the building. The shadow is shown on a lighter building. this makes the shadow seem darker and easier to see.

This photograph shows two different shadows- one of the goal post and the other of the cat. The way this shadow is reflected it looks like a mirror reflection.

The photo of the arched buildings shows clean use of the sun to create the shadow, reflected onto the ground.

This image shows the building from a certain angle so you can see that the building is 3D.

The tire has been reflected as a shadow onto the ground because of the sun light. If a shadow is made then the object must be 3D or a shadow would not form. Therefore i know that the bike must be a 3D object.

This photo shows the shadow of the giraffe on a brick wall. When looking at the image the giraffe seems to be flat against the wall but the shadow makes the giraffe look 3D and therefore we can see that it is not flat. 

The stair case shadow has been reflected onto the wall from the sun light. This creates the effect of the stairs being 3D rather than looking 2D.
