Sculpting with Light

Light is the strongest single lever in any Nano Banana architecture prompt. Because the model understands real-world physics, you should use directional language.

• Do: Use precise directional instructions like "Soft key light from upper left at 45 degrees, subtle rim light from behind right".
• Do: Define the mood via the time of day, like "blue hour, deep blue sky just after sunset, every window glowing warm from inside".
• Don't: Use contradictory lighting sources. Combining "warm morning sunlight streaming through windows" with "moody dark ambient lighting" will confuse the engine. Real rooms have one dominant light source—choose either natural or artificial to lead.
• Don't: Just say "good lighting." The model cannot act on subjective filler.
