Conservez une fiche de référence et contrôlez les visages, vêtements, couleurs et accessoires à chaque nouvelle case.
Getting one attractive character image is easier than keeping the same face and outfit over a complete comic. Gemini's image documentation supports reference-image workflows, but consistent output still needs controlled prompts and visual QA.

Eight-panel continuity review sheet
Use these example checks against C01's original character reference. Mark passes only after inspecting actual generated panels.
| Checkpoint | Locked reference detail | What to compare |
|---|---|---|
| 01–02 · Introduction | Bronze round glasses, asymmetric black fringe | Same eye and hair silhouette |
| 03–04 · Action | Orange patch on LEFT sleeve | Avoid mirrored or missing patch |
| 05–06 · Night scene | Dark-green jacket remains green | Lighting does not change fabric identity |
| 07–08 · Close-up | Small mole below RIGHT eye | Facial anchors still visible |
This is an acceptance rubric, not a claim that a Gemini run passed eight panels.
Guide étape par étape
Follow the sequence using an original or authorized project. The workshop above is an editorial plan, not output falsely attributed to a model.
Step 1
Create a locked character sheet
Draw front, side and three-quarter views. Include exact clothing colors, silhouette, freckles, eyewear and a palette. Use artwork you own.
Step 2
Assign immutable IDs
Name characters C01, C02 and so on. Reuse the same reference images instead of replacing them with later AI outputs after every panel.
Step 3
Control variables between frames
Keep visual identity constant while changing only location, expression, pose and camera angle. Hold art style and lighting vocabulary steady.
Step 4
Review a grid of eight panels
Compare eyes, face width, hairstyle, jacket markings, accessory placement and palette across all eight outputs.
Step 5
Repair just the broken panel
Use the correct original reference and a constrained regeneration/edit. Avoid rewriting the entire issue when one frame diverges.
Prompts à copier
Replace placeholder details with your own original story and reference assets. Paste into a compatible model or workflow; available tools and results differ.
1. Reference-locked comic panel
Character C01 is based on my attached original reference sheet. Preserve their asymmetrical short black hair, round bronze glasses, dark-green jacket with one orange patch on left sleeve, and small mole under right eye. Draw C01 reading a map in a train station. Change only pose, expression and background; no costume redesign or new accessories.
2. Continuity audit prompt
Compare these eight comic panels of character C01 to the reference. For each panel mark face, hair, outfit, palette and props as pass / needs correction. Quote the concrete mismatch; do not claim pixel-perfect identity.
Failure → Cause → Fix
Résoudre les problèmes de création de BD
Specific failure patterns matter more than a generic 'try again'. These fixes target the output you can inspect.
1. The jacket becomes nearly black at night
Cause probable Lighting overrode the garment palette.
Que faire Specify neutral base color and dark-scene lighting separately.
2. Accessories flip sides
Cause probable Mirror/inversion is common when pose changes.
Que faire Call out left/right from the character's perspective and use marked references.
3. After eight panels, the character looks different
Cause probable Generated intermediate art replaced the original ground truth.
Que faire Keep one canonical reference, repair each divergence before continuation.

Questions fréquentes
Why do colors drift between panels?
Lighting and broad prompts can change interpretation; fix named palette colors and ask to preserve costume colors independent of scene lighting.
Does Gemini guarantee a consistent character?
No. Google documents reference workflows and improvements, not an unconditional multi-panel guarantee.
What if one image is wrong?
Repair the offending panel against the original reference instead of using a drifted output as the new standard.
