The Human-AI-Human Handoff: "The Sandwich"

One of the biggest misconceptions about AI Art is that it's a "one-click" process. In a professional environment, relying solely on a text prompt is a recipe for mediocrity. The industry standard workflow is known as the Sandwich Workflow.
1. The Base (Human Input)
Before you even open Midjourney or Stable Diffusion, you should have a plan. A rough sketch, a composition layout in Photoshop, or a "Skeletal Map" using ControlNet ensures that the AI generates exactly the structure you need, rather than hallucinating a random composition.
2. The Filling (AI Generation)
This is where the magic happens. The AI takes your human constraints and fills in the texture, lighting, and rendering details. It does the "heavy lifting" of rendering millions of pixels, but it follows *your* direction.
3. The Topping (Human Polish)
AI is terrible at specifics: hands, text, logos, and specific brand colors. This is where you, the human, step back in. Using Photoshop, Generative Fill, and vector tools, you correct artifacts, composite layers, and finalize the piece.
Key Takeaway: The AI is not the artist; it is the brush. The Human provides the intent (Sketch) and the critique (Polish).
