I may not be so fast, but I agree it is very airy with a nice atmosphere. I get the sense that it is a place in itself rather than a piece of a larger area. Great photo.
The Swiss call it canyon, ok the dimensions are different from US canyons, but it is a cool and rather dark place. I made five or six shots within a radius of 500 meters.
Well, I must say I had some helpers, basically the film (Efke IR), with a "light" red filter (R29) and a compensating developer (MZB) and last but not least a very fine paper.
I was starting to make a choice to have a "bad" day until I saw this. Your work made me remember that there are no bad days just some much better than others. Thank you
