Focus on seven key points for good lighting composition: focal point, shape, form, depth, separation, contrast, and palette. Decide what you want viewers to see first and use lighting to highlight it. You can do this by emphasizing strong shapes and silhouettes for clarity, lighting your subjects to show their form and three-dimensionality, using techniques like Rembrandt lighting, creating depth with atmospheric effects like fog, and separating subjects from backgrounds using backlighting or rim lights. These techniques help viewers quickly understand your images.
