The Cymbidium Orchid image is a reprocess of a 2016 light box image, with a background texture added at the behest of a client. The Cymbidium grows outdoors in our garden (as a transplanted Easterner these many years, this still strikes me as notable!).
The Sidewalk image was photographed straight down using my iPhone 12 in Akureyri, the second largest “city” in Iceland, with a population of about 12,000.
Both are examples of images that in my opinion would not work without color (discussed in More about seeing in Black & White).
