Real and implied circles.
Well, circles are noticeable by their absence, its not until you begin to look around for them that you realise that there are few real circles about. Here are some of the examples of circles that I found.
Implied circles;
So far I have come across few if any circles. This is the closest example that I have found.
I do think it is interesting that the course notes mention that a circle imposes structure on an image, more than say a rectangle or a triangle. I wonder if that is why with the last two photos I find the pictures hard to resolve? When I originally took them I was thinking of the circle framing the main subject. However when I look at them now I find that the circle has itself almost become the subject and my eye finds it hard to travel past the circle. Perhaps if I had constructed the image with the circle not being so prominent it would be easier.
