Neon edge light

Start with the right photo.

Use visible edges and enough dark background for rim lighting to read without washing out the subject.

What to expect

Add electric blue rim lighting while keeping the original scene and readable details.

Keep an eye on

Recognizable identity, silhouette and important visible details. Compare the output to the original before using it.

Make it yours, step by step.

1. Adjust the recipe to describe your subject and preferred background.
2. Copy the complete recipe, then open ChatGPT.
3. Upload your photo in ChatGPT and paste the recipe. The short code alone is not an official command.
4. Inspect identity, text and proportions. Ask for a targeted correction if needed.

Choose the change deliberately.

Separate colored lighting from physical neon tubes. This recipe is useful when the same subject should remain solid while the illumination changes. A neutral patch helps viewers read its original material under the color cast.

Review and refine the result

Look for consistent color on surfaces facing the same light. If everything becomes an outline, request retained surface shading and reduce glow. Try one dominant hue before balancing two competing light colors.

A related direction, and why

/NEONSIGN — Use a tube-sign concept when the silhouette itself should become a constructed luminous line.

Where this effect helps — and its limits.

Useful for a lighting variation. Keep the source scene recognizable; colored light should not replace the subject with an unrelated neon drawing.
