A carousel post works when every slide feels like part of the same story. Swipe from slide one to slide two and the person, the product, or the mascot should still look like themselves, just in a new moment. When the face changes shape between slides or the jacket turns a different color, viewers notice, and the post starts to look stitched together.

Text-prompt image editing makes this kind of set much easier to produce, but only if you plan it before you start typing prompts. This guide walks through a simple process for a five-slide carousel built around one character.

Step 1: Write the story in five lines first

Before you open any editor, write one sentence per slide. Keep it plain:

  1. Character looks at a messy desk in the morning.
  2. Character clears the desk and sets up a laptop.
  3. Character takes a short coffee break by the window.
  4. Character finishes a task and smiles at the screen.
  5. Character closes the laptop at sunset, desk tidy.

This short script does two jobs. It tells you what changes from slide to slide (pose, action, light, props), and by elimination it tells you what must stay the same (face, hair, clothing, overall style). Write that second list down too. It becomes the checklist you use on every slide.

Step 2: Choose one strong reference image

Pick the single best photo or illustration of your character to start from. Look for:

  • A clear, well-lit view of the face
  • Clothing that is fully visible and easy to describe
  • A simple background that will not confuse later edits

Every slide should be derived from this reference, not from the previous slide. If you chain edits (slide two from slide one, slide three from slide two), small drifts add up, and by slide five the character can look like a cousin rather than the same person.

Step 3: Build a "fixed description" you reuse

Write a short description of the character that you paste into every prompt unchanged. For example:

Same woman as in the reference: shoulder-length dark hair, round glasses, mustard-yellow knit sweater, silver watch on left wrist.

Then add only the slide-specific change after it:

...She is standing by a window holding a white coffee mug, soft morning light from the left.

Keeping the fixed part word-for-word matters. If you write "yellow sweater" on one slide and "golden cardigan" on the next, you are asking for two different garments. Tools such as Nano Banana AI are designed to keep a character consistent across poses and edits, but your prompt wording still needs to be consistent for that to work well.

Step 4: Change one thing at a time

Each slide usually needs a new pose, a new action, and sometimes new lighting. Resist putting all of that into one long prompt. A steadier approach:

  1. Start from the reference and change the pose and action.
  2. Review the result against your fixed checklist.
  3. If needed, run a second, smaller edit for lighting or background.

Smaller prompts make it easier to see which instruction caused a problem. If the glasses disappear, you know it happened in the pose step, and you can repeat just that step with a clearer note such as "keep the round glasses."

Step 5: Plan the light across the sequence

Light is one of the quickest ways to make a carousel feel like a story. In the example script, the day moves from morning to sunset, so the light can shift gently:

  • Slides 1–2: cool, soft morning light
  • Slide 3: bright, neutral daylight
  • Slides 4–5: warmer, lower light toward evening

Describe the light direction as well as its color. "Warm light from the right, low angle" gives a more predictable result than "sunset vibe." Keep the direction consistent within the same room unless the story says the character moved.

Step 6: Keep the frame consistent

Viewers swipe quickly, so a stable layout helps. Decide in advance:

  • Where the character sits in the frame (for example, left third)
  • Roughly how much of them is visible (waist up, full body)
  • Where you will put text overlays, so you leave empty space there

If one slide is a tight close-up and the next is a wide room shot, the jump can feel jarring. Change framing on purpose, for one emphasis slide, rather than by accident.

Step 7: Review all five slides side by side

Once you have a draft of every slide, put them in a row and compare. Check against the fixed list from Step 1:

  • Is the face shape and hair the same on every slide?
  • Are the glasses, sweater color, and watch still there?
  • Does the light change in the order the story needs?
  • Do the props make sense (the laptop appears in slide 2 and stays)?
  • Is there clean space for captions?

Fix any slide that breaks the pattern by going back to the original reference and re-running the edit, not by editing the broken version further.

A quick template

Here is a reusable prompt pattern for each slide:

[Fixed character description, copied exactly]. [Pose and action for this slide]. [Light direction and color]. [Background note, if any]. Keep face, hair, and clothing unchanged.

Final thoughts

A good carousel is mostly planning: a five-line story, one strong reference, a fixed description you never rewrite, and small, focused edits. Text-prompt editing handles the heavy lifting of changing pose and scene, while your checklist keeps the character recognizable from the first swipe to the last. Start with a short sequence like this one, review it side by side, and you will have a repeatable process for future posts.
