What characters play a part in this story’s conflict? Which ones are just onlookers?

There are many characters in "Blues Ain’t No Mockin Bird,” but only some of them are central to the story’s conflict, while the rest are onlookers and observers. Granny and Granddaddy are most central to the conflict, as they are at odds with Camera and Smilin over whether the latter two have the right to photograph the couple's property and its inhabitants for the county without permission. These characters come up against one another’s interests throughout the story, through to its ultimate climax and resolution, when the men finally leave the property. The other characters—the children who live with Granny and Granddaddy, as well as their neighbors—are the onlookers in the story; much of the meaning and interpretation of the central characters’ conflict is teased out and explained through the observations of these characters.
