Hi Lucien, welcome to the forum. I can see from your first photograph that you are not in Scotland - those don’t look like rain clouds. An interesting mix of buildings. Nice shot. Where in the world is it?
Welcome, Lucien. Great shots to introduce yourself with. Looking forward to some more.
When you click on edit (below your post) you'll find your attachment with "insert" next to it. Just choose "full image" instead of thumb ... and there you are. When you pull your photo per drag and drop into the empty frame next to your avatar it gets posted in full size.
Welcome to this strange and interesting photographic community, Lucien.
Nice set of images.
Of all of them, this is my favourite. I especially like the clouds and the silhouetted trees. And, yes, the tones and the contrast, as well. I can't help wondering what a large print of this image would look like, on a wall - and how one's perceptions of the print might (probably would) be different from, say, one's perceptions when looking at it on a computer monitor. Either way, it's a great image.
