“You are an idea-driven artist,” my Dad told me. “I am a subject-driven one.” Each year, with the support of my Mum, he took a trip for “material gathering.” Over the course of his life, he amassed innumerable drawings, studies and plein air work, as well as a collection of over 20,000 slides, catalogued by subject and housed in flat sheets above a large light table in the corner of his studio. Like a rainy day bank, the slide library offered a million possibilities for painting subjects, with notations for reference, location, names and dates, if needed. Like a diary of experience, my Dad believed that reference should be personally felt and collected — upholding the authenticity of his authorship and honouring a beloved process and tradition.
