Photograph a child dressed in a ghost costume, holding a teddy bear in a foggy pumpkin patch during twilight. Use a 50mm f/1.8 lens for a shallow depth of field, with the child and teddy bear in sharp focus while the misty pumpkins blur softly in the background. Capture soft, natural lighting with a hint of an eerie glow in the fog for a whimsical yet spooky feel.
