Supreme Court rules against Warhol Foundation in copyright case.

The US Supreme Court has ruled that Andy Warhol infringed on photographer Lynn Goldsmith's copyright when he created a series of silk screen images based on a photograph Goldsmith shot of the late musician Prince in 1981. The case pits an artist's freedom to riff on existing works of art against the protection of an artist from copyright infringement. The ruling is likely to have a big impact on cases involving the "sampling" of existing artworks in the future.
