This time we have two pre­sen­ta­tions that take us to very dif­fer­ent land­scapes and peri­ods in the his­to­ry of stere­oscopy. Andrew Lau­ren will explore how stereo­scop­ic pho­tog­ra­phy doc­u­ment­ed the open­ing up and devel­op­ment of the Grand Canyon, pre­serv­ing views of a land­scape and its ear­ly vis­i­tors that have long since dis­ap­peared. Gert-Jan Wolk­ers, mean­while, will bring us much clos­er to the present with his per­son­al approach to stereo pho­tog­ra­phy and 3D time­lapse, includ­ing recent work made in the Dutch dunes with com­pact dig­i­tal equipment.
