Recommended workflow
- 01
Prepare the input
Choose reference images you have permission to use. For Night Flash Portrait in a Yellow Sports Car Trunk, prioritize a clear subject and avoid unrelated people or private details in the frame.
- 02
Lock the visual plan
Confirm subject count, framing, scene, and lighting before adding finishing language. Resolve conflicts such as close-up versus full-body composition.
- 03
Adapt for one model
Start with Midjourney. Keep a baseline generation and document the exact model version, references, aspect ratio, and visible settings.
- 04
Revise from evidence
Name the visible failure, change one instruction block, and compare it against the baseline. Keep only revisions that improve the intended criterion.
Model adaptation notes
Midjourney
Translate the core fields into concise natural language and add current version-specific reference or aspect controls in Midjourney itself.
Gemini
Provide the JSON with clearly labeled reference images. Restate any ignored constraint in plain language without duplicating the whole prompt.
ChatGPT Image
Keep the JSON structure, attach references in the same conversation, and use follow-up edits for one local correction at a time.
Stable Diffusion
Move observable failures into the interface’s negative prompt field and document the checkpoint, sampler, guidance, and resolution used.
Flux
Preserve the semantic hierarchy but favor coherent natural language; weighting and negative-prompt behavior depend on the host workflow.
A compatibility label means the visual intent can be adapted; it does not promise identical output across providers, versions, or settings.
Prompt-specific quality checklist
- The woman's long ash-brown textured wolf-cut hair must exactly match the uploaded reference image in color, length, texture, density, hairline, layering, natural volume, and overall hairstyle characteristics.
- Her face and hair must remain fully recognizable as the same woman while naturally adapting to the requested pose, perspective, lighting, and composition.
- Include a transparent storage box inside the trunk.
- Include a yellow bottle or a black tube attached to the side panel inside the trunk.
- The bright yellow sports car trunk should occupy most of the composition.
- The atmosphere should resemble an authentic candid analog snapshot rather than a staged fashion shoot.
Failures to check before publishing
- changed face
- altered facial proportions
- wrong hairstyle
- wrong hair color
- wrong hair texture
- different haircut
- cartoon
Why the editable controls matter
Gender
Required identity direction for the reference subject.
People count
Default is a single uploaded reference person.
Identity or subject drift
Reduce competing style language, improve the reference, and separate stable traits from pose, gaze, and expression.
Composition breaks
Check whether crop, shot distance, aspect ratio, subject count, and required objects can all be satisfied in one frame.
Artificial lighting or texture
Name a motivated light source and believable material behavior before adding grain, grading, sharpness, or resolution terms.
