The title is a bit of an exaggeration, it wasn't raining the day this photograph was made. We were near the point where the Squamish River meets Howe Sound looking for Eagles. On the opposite side of the river from our position were the steep sides of the Tantalus Mountain Range. This range rises to nearly 2,000m (that's over a mile) from the sea level of Howe Sound. The clouds were mingling with the trees on the slope.
The picture was made with a 80 -200 mm lens at f2.8 at 1/30, handheld. It was the shortest lens we happened to be carrying with us and the clouds were moving too fast to consider removing a long telephoto lens we had sitting on the tripod. The picture is just a little bit soft (you might not be able to see it in the web images), but it adds to its feeling.
