Grow a community of followers and collectors with interactive virtual exhibitions

On first impressions, a virtual tour of an artist's exhibition is simply a representation of art mounted in an exhibition. But it is much more. Visitors know about an exhibition from word of mouth, advertising or perhaps a festival promotion. Those who know the artist will already be "in the loop." Add a virtual exhibition to extend the reach to many more potential viewers using numerous channels. How do virtual exhibitions attract more visitors, increase the number of followers and boost the number of collectors?
