Last year, Taschen released a book of Helmut Newton Polaroids. As did many photographers, Newton used Polaroids to test a shot before shooting actual film. His widow, photographer June Newton (a/k/a Alice Springs) edited the book.
I fondly remember using the Polaroid 110A and 110B converted with Polaroid backs for test shots ... and then the dinky 600 just for fun ... and then the Spectra with which I must have taken hundreds upon hundreds of shots, none of which were test Polaroids, but instead just for the thrill of instant gratification and spontaneity.
