Photo taken with an iPhone 7 Plus.
When I took this photo I didn't notice the man walking into the frame. My daughters were harassing me about playing on the playground, and the sun, which was glaring in my eyes, kept me from seeing the detail on the screen through my polarized sunglasses.
The two dots on the water are buoys and the blue dot in the sky was lens flare from the sun, unintentionally lined up with the contrail, making it look like it was flying through the sky.
A pretty impression composition considering it was almost entirely accidental and not edited in any way.
