Prompting Basics

A good prompt is a compact brief. The most reliable results come from describing the subject, the visual treatment, and the context in clear, concrete language.

The prompt bar keeps model, ratio, and generation controls in one place.

A Simple Prompt Formula

Subject + Style + Composition + Lighting + Medium

Example:

"Ceramic tea set on a walnut table, warm studio light, top-down composition, editorial product photo"

Make It Specific

  • Subject - What is the main object or scene?
  • Style - What mood or aesthetic do you want?
  • Composition - Close-up, wide, centered, rule of thirds, top-down, etc.
  • Lighting - Soft daylight, rim light, neon, golden hour.
  • Medium - Photo, illustration, poster, screen print, 3D render.

Iterate Intentionally

  • Change one variable at a time (lighting, style, or composition).
  • Keep notes on what produced the best results.
  • When you land on a strong direction, save it as a reusable prompt.

If you plan to print, consider:

  • Clear subject separation for clean edges.
  • Simple backgrounds if the product has bleed or margins.
  • Aspect ratio that matches the intended product shape.
