The photos with clearings in the thickness through which the sun's rays enter are inspiring. Ltuya is very well achieved thanks to the low contrast, as you indicate. I liked not only that the luminosity of the rays could be perceived through the darkened branches, but also the sky in the background. I did some on that line long ago, when I had a camera (although not professional). I think I posted one in Steemit at some point. Thanks, @velimir.
