You've probably spent hours tweaking AI prompts, only to get portraits that look flat, poorly lit, or just plain amateur. The lighting looks off, the shadows fall in all the wrong places, and you're left wondering why your generated images don't have that professional polish you see everywhere else. It's frustrating when you know exactly what you want but can't seem to communicate it to the AI.
These 12 expertly crafted prompts give you the exact lighting terminology and technical details that AI image generators understand best. Each prompt targets a specific professional lighting technique, from classic Rembrandt lighting to cinematic low-key setups, complete with angle specifications and style descriptions that produce consistently stunning results. Instead of generic portraits, you'll generate images with intentional lighting that rivals professional photography studios.
