Who said if you pose you will forget posing and t here is fact?

The quote "If you pose, you will forget posing, and there is fact" is attributed to the American artist and photographer Robert Rauschenberg. He is known for his innovative approach to art and his emphasis on the importance of authenticity in artistic expression. Rauschenberg's work often blurred the lines between different mediums, reflecting his belief in the power of genuine experience over mere representation.
