Empress Eugénie and Napoleon III are dressed to go out in this photograph.
Disderi invented the carte de visite (cdv).
From Wikipedia; blotches and spots had to be removed from throughout the image with Photoshop.
Empress Eugénie wears a jacket contoured to the dress beneath instead of a paletot. She also wears a bonnet, headwear that was becoming passé. The dress may be the one shown in the preceding images - it appears to have five flounces, four of which can be seen in this image.
