Nacreous clouds

After lurking on this forum for many years, I decided that it was time to start posting myself, so here is the first one!

This was a beautiful event, nearly two years ago. I just went out for a short hike, but very quickly became aware of some strange clouds above me. The whole experience took several hours, during which the clouds changed appearance continuously. I totally forgot about the cold, until I got home and had a really hard time handling my apartment keys with frozen fingers! Awesome! I really hope this was not the last time I got to witness nacreous clouds.

Sweden, februari 2011. 105 mm (35 mm equivalent), 1/8 sec, f/11, iso 100.

Beautiful! The sky is surreal and looks like timed exposure of a river. And the elegant detail ..sharp and stoic...of the silouette is a bold contrast against the motion of sky. Look...this is setting a high bar! Tough to follow...but we'll be watching!!

I will add my welcome to NPN. This is a very dramatic and powerful sky. I would be tempted to crop more off the bottom. Crop it up close to the trees. There is a lot of negative space on the bottom.

Welcome, Roel. I had to Google "nacreous clouds" to find out what they were. Interesting phenomenon. These seem lower, but there is some iridescence here and the shapes seem typical. The silhouettes are a nice addition, though they do get lost a bit in the black frame.

Love the textures of those clouds. The silhouetted tree line is very nice too. Perhaps a small crop from the bottom to remove a bit of black. An amazing sight it must have been.

Thanks for the comments and kind words! I didn't know either what nacreous clouds were, until I saw this and started to search on Google. Maybe I should have described them in my post.... Anyway, nacreous clouds form at really high altitudes (~20 km) and form when temperatures drop below -80 degrees celsius (-112 degrees Fahrenheit). Because they consist of tiny ice crystals, they refract light which result in very colorful clouds. And if that isn't enough, they also turn bright orange, long after the sun has set and the sky has darkened. This is because of their altitude, they still receive light from the sun when we no longer see it.

About the black part, I played around a bit with the picture and cropping does seem to be a good idea. Although it looks a bit worse here because of the black frame.

Tony, the reason these clouds seem lower than normal is because I ignored the higher parts for this picture! There was some nice stuff going on higher in the sky as well.

Those clouds are absolutely stunning Roel, and perfectly set against the silhouetted BG. Congratulations on a tremendous first post, and welcome, wow!! :smile:

First of all, welcome to NPN and to the Landscape gallery - it's great to have you here. Excellent first post. The clouds are phenomenal in both shape and color - exquisite IMO. I'm also impressed by the sharpening - the trees are very crisp but without any hint of over-sharpening. Looking forward to future posts and participation!

Nacreous clouds? Never heard of them before, and living here in Florida (deep south USA), I'm not likely to ever see them! :biggrin:

Welcome to NPN Roel. Fascinating clouds. It looks like flowing water in a stream.
