Hi

I saw your question on Stackoverflow at 
http://stackoverflow.com/questions/28271240/schema-org-microdata-markup-to-distinguish-between-photos-and-art 
and it look's like user Unor has answered your question comprehensively.

As Unor mentioned in their answer, a new schema for VisualArtwork will 
be released very soon (hopefully just a matter of days) that will enable 
you to mark up photos with http://schema.org/Photograph and art with 
http://schema.org/VisualArtwork.
