playing with shadows... actually, i was trying to figure out something clever to do with the opaque theme, but nothing was working... so i did this ;p
"opaque" because the chess pieces are opaque... as the light did not pass thru them, they cast a shadow on the paper that was between them and the camera lens...
@marinashemesh tx :) in the interest of full disclosure, i actually did comparatively little processing here (at least by my standards!)... cropped and straightened, tweaked contrast and converted to black and white...
I was thinking about opaque too, but after looking at the definition it is harder than I thought!
Very cool and clever, indeed… ;-)
