Thank you Peeter for your words. Yes, I absolutely enjoyed those sandstone caves at sunset time where the low sun could send some rays inside. I assume the paradoxes you mentioned were when I saw a glow in the darkest part of the cave in a place the rays can't penetrate. ( this was not possible to photograph and disappeared in a minute ). I also liked the forest above the caves ( with many mushrooms ) and how the rays came inside between the timbers.

Pini's picture shows once again, that it is possible to paint some light on the stone. Or to find that particular wall where there is still some adhesive light on it. I know Pini is mastering this kind of light capturing more and more - I've seen him working in South-Estonian sandstone caves where he turned my attention to some specific optical paradoxes.
