Tar spot makes a picture

Over the past weekend, my wife and I visited Montreal. Strolling an elegant, older neighbourhood, I noticed many of the colourful, fallen maple leaves exhibited large circular tar spots, the indicator of a distinctive fungal infection of maples.

As the overall health of the tree is seldom threatened, approaching tar spots as  graphic elements in a fall leaves composition did not seem too callous. I tried to find at least three affected, fallen leaves with each a different colour. I framed the image with a triangular composition that also drew on the rule of thirds for success.
