Remember, this website is called “Guess” the Lighting. Therefore, all lighting, camera, lens, grip, f-stop, shutter speed, etc. information may not hold up in a court of law. Any guesses as to what the featured photographers were wearing, drinking or pondering while creating the shots are not necessarily subject to any reality other than my own. Suggestions of marital problems, hangovers, jet lag, disease or any other contributing factors should, likewise, be taken with the proverbial grain of salt.
There is a lot of guesswork in guessing.
