A conservation and examination technique where light is directed across an artwork's surface at a low angle to reveal texture, brushstrokes, and surface irregularities. It helps detect damage, repairs, and painting techniques.
From the verb 'rake' meaning to sweep across, combined with 'light,' developed in 20th-century conservation practice. The term describes how the light literally rakes across the surface, creating shadows that reveal texture.
Raking light can reveal an artist's personality through their brushstrokes – Van Gogh's thick, energetic impasto creates dramatic shadows, while Vermeer's smooth technique shows barely any texture! It's like a lie detector for paintings, exposing hidden repairs, overpainting, and even the artist's emotional state while working.
