OK, I've decided to bite the bullet and post an image for critique. Black and white is not something I do very often so it would be interesting to see what you good folk think of this one.
I edited this in Lightroom by tweaking the colour sliders in the Greyscale section until I got something I liked the look of. I've also increased the contrast slightly.
The image was taken at about 2.30pm on a very bright day just over a week ago. I was trying out a Canon EF 24-105mm f/4L IS lens that I had hired. Taken at 45mm, 1/80 at f/11, ISO 200.
I want to purchase either this or the EF 24-70mm f/2.8L (which I've also rented a few weeks ago) for portraits, but I was trying to assess its capabilities for landscapes as well, as I've been having certain doubts about my existing arsenal of Sigma lenses.
