The obvious, brief-glance comment would be to moan about he centred composition ... but of course this is not centred. The cleanliness of the aircraft, and the dissipation of the contrail into a murky brown that speaks of pollution, especially against the deepest blue suffusion of the sky brings the political to this image; some suggestion of the battle of the giant airlines against the perception of their trade as damaging to our world - everything must be shiny bright, but leaves a trail of waste and poisons. The bluntness of the placing of the plane in frame adds to this effect beautifully, disrupting that almost complete darkness. 9
Simple photo but not so simple to take and render. I like the nearly black sky and the high contrast with the subject. The sky especially is exceptionally and I like the way it gradients from midnight blue to black at the edges. Maybe it's just my monitor but it's very subtle. Among my top pics. Hope it does well.
