After taking the preceding image, I changed the point of view slightly and replaced the 450mm lens by a 600mm. The ground glass was so dark by then that I had to focus on the small patches of the sky through the branches. My spotmeter could not read any more, so I closed to f16 and exposed for twenty minutes, till it was dark. By chance, there was not the slightest breeze in the foliages, whereas I had to force my own breathing!
