What does the term 'Alla Prima' mean in painting?

The term 'Alla Prima' refers to a painting technique where layers of wet paint are applied directly onto wet paint without waiting for the previous layers to dry. This method allows artists to create more spontaneous and immediate work, as it encourages a direct approach to capturing the subject. It is often associated with impressionist and plein air painting, where the goal is to capture the moment and the effects of light and color quickly. This technique contrasts with methods that require drying periods, such as layering oil paints or using colored washes, which focus more on the buildup of texture and detail over time. Therefore, 'Alla Prima' aptly describes a method that embraces immediacy in the painting process.
