From Wikimedia; this was a difficult image to prepare. There were numerous spots of various sizes throughout the image as well as large cracks (fixed) and smaller ones (sometimes fixed) to work on with Photoshop. The background was also fixed with Photoshop. Before that, I filled in the shadows and increase the exposure.
The Wikipédia.fr article about this painting has some biographical information about the Countess.
Countess Daru wears a floral headdress and a parure of semi-precious stones with a typical Napoléonic dress for her 1810 David portrait.
