For this exercise we are required to taking photographs of triangular compositions
Real Triangles....
This was quite an obvious triangle to spot but what I like about this was that the triangle of the roof pitch was sitting on top of a square building which was nicely isolated from other buildings, and the triangle element of the roof is almost bordered in black in contrast to the white "equilateral" triangle against the light colouring of the sky. I've framed this image with the door on a vertical third. I preferred the obviousness "in your face" of the triangle in this image compared to the slightly less obvious "isosceles" triangle formed by the tower of this church in Lydney in the image below:
For this image in addition to emphasising the dark "triangle" of the church tower against the light sky I also like the horizontal layering of the darker clouds, the lighter sky and the dark foreground.
Make a triangle by perspective converging towards the top of the frame
I've taken this image in landscape understanding that this would allow more of the railway lines to be included in the image and understanding that I would need to crop less from the top of the image which I wasn't able to completely eliminate when composing the image. Here I've captured the pair of railway lines each forming 2 "curved" triangles within the larger triangle of the outer railway lines where perspective of distance has them converging at the top of the frame forming the peak of the triangle(s). The white line of the platform edge helps to add a lead in line to the image and together create an implied sense of movement as the eye follows the white line and the railway tracks toward the top of the frame.
Make an inverted triangle by perspective converging towards the bottom of the frame
I found this a particularly difficult task and too be honest I feel the quality of my image has suffered as I've over compensated to find an inverted triangle.Finding two strong tree trunks and through the positioning of the camera I've created an inverted triangle where the position of the camera creates the converging peak of the inverted triangle at the bottom of the frame. The curved diagonal tree trunks within the frame create a sense of dynamic movement in what is really a very static image. The different colour of the tree trunks compared with the others help the viewer to pick out the triangle shape....I hope!
Implied Triangles
Still life arrangements of five or 6 objects. Well it could have been easy to cheat here by having both normal and inverted triangle in the same image being also economic with the number of items reduce to one. Here I've created implied triangles at the top with scissor blades and bottom with scissor handles. I've put the scissors in the bottom of the frame to avoid it looking as if it's floating in the middle
Implied Triangle with Apex at the Top
Some kitchen utensils laid out not quite haphazardly on a black t-shirt. I've created an implied triangle here with the left and right hand edges starting almost in the corners to help create diagonal sand therefore slightly energetic lines. If you look hard along one of the edges you may glimpse a metal man....depending on your imagination
Implied Inverted Triangle with Apex at the Top
Very simple image of knives and forks appearing as if on a table cloth but is fact a black shirt slightly ruffled so that the undulations give some additional interest in the image with the different shades of black and the shadows.
Three People in a Group Picture
The exercise was to create an image of 3 people in a group and create an implied triangle where either their faces or bodies create a triangle.
In the image below I have created 2 triangles in between the 3 children using the body shapes / arms. You'll also see in the background an additional triangle of the buildings roof
This image helps demonstrate the triangles between the children
Exercise Learning's
a) Implied triangles can be easy to create in images because they require 3 points and like quadrangles there are many about in every day life naturally
b) Perspective using converging lines can also be created from items such as tall buildings, roads, and as I've used above railway lines which in this image are visible but in other images can be implied
c) Triangles can be created very easily using points in a view by amend camera plane or angle very slightly to take 3 points of interest and create this interlinking of the points to create a triangle shape
d) Triangles / Implied triangles will invariably have two diagonals and these can be used to help create movement or energy within an image
e) the apex of a triangle can help direct the viewer to a point of focus or perhaps simply helping to move the eye through the image so its completely explored
