At dawn, Jen Casad digs for clams on a coastal mudflat in Maine. At dusk, on that same mudflat, with the same low tide, she digs for clams again. In just two static shots, multimedia artist and filmmaker Sharon Lockhart captures not just the hard work of clam digging, but also everything about the environment surrounding it that words could not express.

Through its stillness and simplicity, Double Tide allows us to truly sit with the repetitive, taxing process of coastal labour in its entirety without sacrificing any of its natural beauty. Across the film’s two long takes, the same picturesque backdrop is radically transformed by light and weather conditions, serving as a reminder of Jen’s dependence on an ever-changing environment.
