No, not my thinking!! Photos!
Let me explain. In our family room, on the wall opposite the kitchen door, we have a group of black and white photos. A used to be into b&w photography in a big way, and had his own darkroom. Times change.Now all our photography is digital, we each have a camera and get a lot of fun from it, though our photographic "styles" are very different! At the moment we are in the process of replacing the photos on the wall (something we do periodically) and so are picking out a few photos, converting them to greyscale, enhancing them and printing them.
