As photographers know, they often are asked what they are doing. Duh. With camera and tripod in hand, why would someone need to ask? But sometimes you have to state the obvious. Hence, one photographer has developed a line of clothing
that declares "Photographer Working" in several languages. The designer, a commercial photographer, came up with this idea after many years of shooting when he constantly would have to field questions about who he was and what he was doing. Unfortunately, it makes sense, even when some don't demonstrate any.
