Roy Kerckhoffs Art in Carlsbad's Aviara district produces hand-colored black-and-white photographs of California's coastline and architectural landmarks from a home studio at 6397 Ebb Tide Street in the 92011 ZIP code. A Dutch-born artist who holds a PhD in bio-engineering from UC San Diego, Kerckhoffs transitioned from scientific research to full-time art in 2014, applying photo oils, acrylics, watercolors, and pastels to his monochromatic prints in a technique that mirrors early twentieth-century hand-tinting — an artisan precision shared by the scale-model craftsmen exhibited at the KHARA Collective on Carlsbad Village Drive. His coastal portfolio focuses on lifeguard towers, wooden beach staircases, and weathered infrastructure from Carlsbad State Beach south through Cardiff-by-the-Sea, with limited-edition prints framed in reclaimed barnwood. Permanent installations include all guest rooms at Cape Rey Hilton Resort on Ponto Road, meeting-room triptychs at Carlsbad by the Sea Resort, and wall collections at a UC San Diego residency building. The Bodie ghost-town series and composite reef photography complement the coastal work, echoing the industrial-meets-organic aesthetic explored in the precision-machining exhibits at Craftsmanship Museum on Faraday Avenue. Each original hand-colored photograph involves selective oil application using cotton swabs, fine brushes, and sponges over archival inkjet prints, with size-limited editions capped between eighteen and thirty prints per image dimension.
