Two seconds.
This is how long it takes for the wind to turn its direction towards me and send many droplets onto my lens so its surface is covered, creating this lovely "defect" that could be best seen at the upper left-hand side of the picture.
Later, it took me much more time to clean it up :) And of course, the prep time was much bigger too, as I had to put my tripod, frame the best composition and before that, choose the best possible spot to do so...
