Example prompt: Create a practical product size comparison photo of a compact portable bluetooth speaker shown alongside common objects for scale reference. The speaker (approximately 3 inches tall) is positioned in the center with common reference objects carefully arranged around it - a standard US quarter coin, an iPhone 14, a credit card, and a standard coffee mug. All objects are positioned on a clean white surface with a subtle grid pattern that provides additional scale reference. The lighting is bright and even to ensure all size relationships are clearly visible without distracting shadows. The perspective is directly from above (top-down view) to prevent perspective distortion that would interfere with accurate size perception. Include a small ruler along one edge of the frame showing both inches and centimeters. Capture with informational photography techniques including distortion-free perspective, consistent arrangement for clear comparison, and visual alignment cues. Render in a clean, objective photographic style with perfect clarity, neutral color treatment, and accurate proportional relationships, ideal for helping online shoppers understand the product's actual size.
