Course: Inpainting & Loss Compensation on Paper


Can you match the colour but not the surface texture? Can you match the surface sheen but not the colour? Do you struggle with both? Do you never know what dyes to use? If you want to acquire a wider range of inpainting techniques, this is your course. Held by knowledgeable professionals, it goes deeper into the tools, materials, techniques and tricks. The goal is to infill and in-paint the most challenging losses with confidence and success.
