A blended background has entered the edges of the main subject. What should be done next time to prevent this?

Correct answer: Keep moisture lower near the subject boundary and use small controlled strokes

The governing concept is edge control during wet blending. Excess water, a heavy paint load, or pausing at the boundary allows pigment to pool and travel into the subject. Keeping the area near the edge less wet and using short, controlled strokes limits capillary spreading while preserving a clean contour. Option A is correct. More water, pre-wetting the subject, or depositing extra paint would increase bleeding and pooling.
