I was recently challenged with one of those Facebook photo challenges. This particular one was to post a black and white image of your daily life, no people, no explanations for 7 days. It turned out to be rather fun. It also got me to dust off my copy of Silver Efex Pro as well as Tonality to do the black and white conversions.
Certainly not photographic masterpieces by a long shot but I did learn that much of my daily life is centered around dogs.
