Exercise 22. Real and Implied triangles

The exercise requires to produce two set of triangular compositions, one set 'real' triangles the other set 'implied' triangles.

Set 1.  Real triangles, three parts:


Part . 1

Fig 1. 

  f/5.6     1/320sec    Shutter priority     105mm      ISO 100

Home coming - Oman sail

The sail which is itself a triangle.

Fig 2.

Manual mode   1/400 sec     f/5.3     ISO 125    70mm

   

Adornment.

This head wear is clearly constructed of 4 real triangles. This triangle is a 'stable' as it is sitting on its base.  

Part 2.  A triangle by perspective 

Fig 3. 

f/8.0     1/200 sec    ISO 100    18mm 

This image is intended to show the triangle is created by perspective converging towards the top of the frame.

Part 3.  Inverted Triangle 

Fig 4. 

Aperture priority   1/30 sec    f/14.0    ISO 200   80mm 

   

'Reflective'

This photograph shows an inverted triangle created by perspective, this was not an easy one for me to achieve and I am not totally happy with the outcome.  The inverted triangle that I see is created by the silhouette of the tree on the grass bank, captured just before sunset.  

For the second part of this exercise, I have to produce three images showing implied triangles.  


Part 1- still life, apex at top

Fig 5.

f/16.0    1/30 sec     35mm    ISO 100   Tripod Utilised 

'Barriques de vin anciennes' 

The 6 barrels stacked in such a way to create the implied triangle in this photograph, with the apex crowning the 5 lower barrels.

Part 2 - still life, inverted, apex at bottom

Fig 6. 

f/9.0     1/30 sec     35mm     ISO 200     Tripod utilised.

The huge decorated lanterns hanging at various heights create a stunning implied triangle in the open space.

Part 3 - group picture 

Fig 7.

f/2.8    ISO 200    1/60sec    Flash used 

'New friend'

The heads of the three friends create the outer line of the implied triangle.

Fig 8. 

f/8.0    1/125  sec     ISO 100   37mm    

'Passing the time of day'

An image I captured in Nepal,  5 Nepalese shop workers passing the time of day, two very distinct implied triangles in this photograph, the group to the right being one, and the apex of the second implied triangle being the lady standing above all others. 

My thoughts on this exercise

• The triangle is a geometric shape that appears often in life and are easily recognisable.
• They can be created when connecting together imaginary lines between three points
• When used correctly the apex of the triangle can lead the eye through a photograph.
• It is the simplest of all polygons and the implied triangle is as strong in an image as a real triangle.
