Join ideaLAB at the Denver Public Library and History Colorado for a Photo Mash-up Family Workshop! Participants will start at History Colorado’s library and research center to choose a historic downtown Denver photo from their archives for your project. Next, you’ll hit the streets to photograph the same spots featured in the photos. Finally, the group will meet up at ideaLAB to mash the historic and current photos together in Photoshop. Registration required: Email [email protected] by Sept 11 to RSVP your family.
