Based on the Central Coast of California, ExpoImaging designs, manufactures, markets and distributes innovative photographic accessories.  

ExpoImaging is the pioneer in digital white balance filters. It is the manufacturer and exclusive worldwide distributor of Rogue Light Modifiers and ExpoDisc Professional White Balance Filters. ExpoImaging is also the exclusive North American distributor of Nissin Digital Flashes.

ExpoImaging's first product, the ExpoDisc White Balance Filter, was the brainchild of ExpoImaging CEO Erik Sowder's grandfather George Wallace.

ExpoImaging then created the Rogue Photographic Design brand for portable lighting tools.  Rogue FlashBenders shapeable light modifiers were the first products developed under the Rogue brand. The latest Rogue tools include Rogue Round Flash Magnetic light modifiers.
