This book compiles the complete array of slides Frido Troost (1960-2013) utilized during his lectures at the Gerrit Rietveld Academie. Troost, who was an art historian, pioneered the collection of diverse photographic forms. His shop, the 'Institute for Concrete Matter,' showcased a broad spectrum of photographic art, ranging from daguerreotypes to albumen prints and from stereoscopic images to family albums.
The visuals in this publication are derived from a variety of sources including paintings, advertisements, erotica, art pieces, and portraits. They assemble into a new collection that mirrors Troost's associative visual approach. The slides are organized into blocks of nine, echoing the non-hierarchical structure Troost employed in his teaching, which encourages viewers to freely connect the images. This eclectic compilation spans a significant swath of photographic history.
