I often end up with odd images that represent nothing much more than items that caught my eye as I walked around.  When I display them together, they don’t represent much more than visual clutter, especially in color.  That is one reason I like to publish them as toned B&W images … to remove the visual clutter of disparate colors.  I don’t have anything against colors, but I also like B&W as well, and I use both depending upon my mood, how I’m grouping them, and what the story is about.
