Structure

A MOSS Image prompt, piece by piece

Write in this order and keep each part concrete. Physical detail works better than mood words.

  1. 01

    Subject

    The main subject and its key details: material, colour, expression, product features.

  2. 02

    Composition

    Framing and angle: close-up, flat lay, three-quarter view, rule of thirds, negative space.

  3. 03

    Setting and light

    Background, environment and lighting: studio softbox, golden hour, neon.

  4. 04

    Style

    Photo, illustration, 3D render or painting — plus lens or medium details.
