Since 6.30am on Monday morning, the Unseen production team has been working on the build-up of Unseen Photo Fair 2012. From the Gashouder to the Zuiveringshal West, the Westergasfabriek has been transformed into the location of Unseen, a photo fair with a festival flair. Participating galleries at Unseen Photo Fair arrived on Tuesday afternoon to set up their stands. Today, galleries are adding the final touches before the press preview and official opening that will take place tonight. Here, we share a few photographs from the build-up. Be sure to check out our Facebook album for more photographs. We look forward to welcoming everyone tomorrow!
