Leave nothing to the imagination

To “leave nothing to the imagination” means to show or describe all of the parts or details of something. The electronic media (in the 9-11 Museum), though, “doesn’t leave anything to the imagination.” The electronic media in the museum reveals many details of the attacks and aftermath. This expression is often used to describe situations that are crude or obscene. The movie’s surgery scenes “leave nothing to the imagination,” or the surgery scenes show graphic imagery during surgeries.
