Jayanti Seiler is not shy about expressing her feelings for animals. But when she meets the subjects of her project “Of One and the Other,” she keeps those feelings to herself. She has explored the contradictions of the human-animal relationship, photographing them at circuses, shelters and even taxidermists. She started with birds of prey but soon expanded to include other animals. Ms. Seiler, 38, has always been an animal lover, so after she volunteered at a Florida wildlife rehabilitation center, she was inspired to chronicle the complex relationships she witnessed.
