Hello, just to let you know this isn't a homework question so.......yea. <u><em>:)</em></u>
Edward Weston used the balance in <em>difference in value</em> to create contrast in the photograph 'shell', taken in 1927. The shell was a medium sized black and white photograph image that featured a nautilus shell balanced within an abalone shell that rested on a semi-reflective surface. The shells are set against a plain, dark background with pale tones that shine against it thus showing the difference in value to create contrast.
