Don't just say "dog"; say "a golden retriever puppy running through a field of wildflowers, golden hour sunlight, bokeh background". The more descriptive you are, the better the AI can align with your vision.

• Adding Context and Intent: Think about the *purpose* of your image. If it's for a book cover, mention that – it subtly influences the AI's stylistic choices. Google's experts recommend "thinking like a photographer". Specify camera angles (e.g., "wide-angle shot," "macro close-up"), lighting conditions ("soft morning light," "dramatic chiaroscuro"), and overall mood ("serene," "energetic," "mysterious").

• Iterative Refinement: Your first prompt rarely yields perfection. Use conversational editing to your advantage. Generate an image, then tell the AI what you like and what needs adjustment. This back-and-forth is key to achieving precise results.

• Positive Framing: Focus on what you *want* to see, rather than what you *don't*. Instead of "no cars," try "an empty street with historic buildings". Positive affirmations help guide the AI more effectively.
