Prompt structure that works

For Flux Kontext Pro, the prompts that perform best follow a predictable structure:

• Subject first: lead with the main thing in the frame ("vintage Roland synthesizer", "musician in a rain-soaked alley")
• Style and lighting next: how it should look ("photorealistic", "35mm film grain", "soft purple bokeh", "golden hour")
• Composition and aspect: framing cues ("close-up", "wide shot", "16:9", "magazine-quality")
• Mood and atmosphere last: the emotional pull ("moody", "cinematic", "dreamlike")
