This week in arts: the (e)merge arts fair, Ai Weiwei, Artisphere’s second anniversary, the D.C. Fine Art Photography Fair, and a discussion on preservation.

Looks like 300,000 square feet won’t suffice for Artomatic, the massive art exhibition that in May is scheduled to open its first event in three years. It will now be held at an even larger building.

Artomatic, the giant free-for-all art fair that has been on hiatus since 2009, is coming back bigger than ever.

The (e)merge art fair explains that it is the first American event to feature “a virtual art fair originating from a physical fair.” But the physicality of the fair is what makes or breaks it, and where (e)merge is most successful is where the artists and galleries make the best use of the Capitol Skyline Hotel.
