2D ART
In the 18th century 'candle silhouettes' were a popular form of portraiture because they could be drawn in one sitting and were therefor affordable. A single candle was used to cast a shadow of the sitter's profile in silhouette.
I used this method of single source light to sketch the silhouettes of some writers and artists I met at the Vermont Studio Center.
The God Janus is depicted with two faces to look to the future and to the past simultaneously.
