Becca Bland is promoting a non-photography day for 17 July. I can appreciate the point she is promoting. Many people spend an entire holiday behind the lens of a camera or video recorder. Maybe they can watch it later to find out out if they had a good time.
I don’t think that having a specific day is appropriate though. Each day has a specific meaning for individuals and different needs for capturing the moment. You can’t ask somebody not to take photos on their wedding day or in a place they may only visit once.
I think she is right though, the hasty reach for the camera can disrupt the moment, particularly a landscape or the feeling of an event.
