Exercise: Real and Implied Triangles

In this exercise I am to produce 6 photographs; 3 of real triangles and 3 of implied triangles. Real triangles are where there are distinct 'lines' or contrasting tones that form the shape of a triangle. Implied triangles are where points or smaller shapes come together to for the shape of a triangle. 

A real triangle

A painted give way sign in the road.

Triangle by perspective, with the apex at the top.

Both the apparent narrowing of the path, and the trees appearing to close in further in the distance, give the impression of a triangle.

Inverted triangle by perspective. (apex at the bottom).

The shape of this Labrador's head, particularly because of the sightly pricked ears, forms an inverted triangle when viewed top down.

A still life arrangement in the form of a triangle, with an apex at the top.

I didn't want to make this too obviously a triangle so I just made a bit of a haphazard attempt at balancing the books against the central one.

Still life inverted triangle - apex at the bottom.

I have attempted to create an inverted triangle by having a downward perspective on items which get wider the further back they are  in the scene. I did think of removing the dried wheat as it was slightly ambiguous but looking at it again the stalks do actually fan out and create their own triangular shape.

Three faces forming an implied triangle.

I thought it might be interesting to use two mannequins in a shop window to form two corners of the triangle and then wait for a passer-by to move in between them.
