Lighting a wall of small paintings is best accomplished by?

Washing light is considered the most effective method for lighting a wall of small paintings as it provides a broad, even distribution of light across the surface. This technique ensures that each painting is adequately illuminated without harsh shadows or hotspots, creating a uniform visual experience. A wash of light can enhance the colors and details of the artwork, making it stand out while also maintaining a subtlety that complements the overall display.

When considering other techniques, grazing light focuses on highlighting texture by casting light at a low angle across the surface, which may not be suitable for multiple small paintings where a uniform brightness is desired. Modeling with light and shadow creates contrast and depth, which can be effective for three-dimensional objects or single pieces but may not adequately serve a collection of paintings where consistency in lighting is important. Focal light concentrates illumination on specific points, making it ideal for singular artworks or features but potentially ineffective for an entire wall of art where a softer, more encompassing approach is required.
