I am looking for the title of a short story I read many years ago in a collection of RB stories that included the Skeleton. The story was about a high-fashion model photographer in a Central American (?) country who encounters a native who insists on being paid for being the backdrop for the model. Thanks!

Appears to me "Sun and Shadow" (originally collected in THE GOLDEN APPLES OF THE SUN, 1953 then) in THE VINTAGE BRADBURY(1965), which includes "The Skeleton."
Hope this helps.
Cheers,

Actually, the native wasn't wanting payment, he was simply morally outraged at his neighborhood being used as a backdrop to depict "local color." The name of the story is "Sun and Shadow" and it has appeared in prose and play form and as an episode of "Ray Bradbury Theater."
