It isn’t about parking tickets.
Several of my past photos contain yellow lines; I have a knack for stitching them into the composition. The yellow adds a vibrant touch, and the angles ‘cut’ into the photo. Not to mention that it is in harmony with the greens and magenta, on an otherwise dull asphalt road.
I have been abusing F/2.0 so much that I wonder if it can be considered cheating. Abuse away!
