+- ParkPhotoViewSet: CRUD operations, custom actions, permission checking
+- HybridParkAPIView: Intelligent hybrid filtering strategy
+- ParkFilterMetadataAPIView: Filter metadata retrieval
+
+Test patterns follow Django styleguide conventions with:
+- Triple underscore naming: test__<context>__<action>__<expected_outcome>
+- Factory-based test data creation
+- Comprehensive edge case coverage
+- Permission and authorization testing
