Photography
"f/8 and be there" is an expression popularly used by photographers to indicate the importance of taking the opportunity for a picture rather than being too concerned about using the best technique. Often attributed to the noir-style New York City photographer Weegee, it has come to represent a philosophy in which, on occasion, action is more important than reflection.
