Single point dominating composition
Here I used depth of field to exclude the background and emphasis the single point of focus, making the flower head and stem dominate the composition.
This image has two points at either side of the composition.
Distinct shape - circle
Whilst taking these photos I experimented with an up close photograph of the flower head and was very pleased with the result. This is a definite circle shape and as such will also be submitting it in my assignment.
