Abstract
A photography lightbank is extendable axially and radially to a larger size by an extension ring, which is removably attachable to the distal (front) end of the lightbank shroud. Extension rod connectors are configured for attachment of extension rods, which support the extension ring in outstretched configuration, to the distal ends of the primary support rods that support the lightbank shroud, while releasable fasteners attach the proximal end of the extension ring to the distal end of the shroud.
