Fix a Blown-Out Sky Without a Reshoot: Step-by-Step Guide

We’ve all been there: you finally nail the perfect shot, but the sky is completely blown out. Pure white, no detail.

Normally, you’d think the only solution is a reshoot… but not anymore. With a little AI magic and a few smart editing steps, you can rebuild that sky in minutes and keep your project moving.

In this post, I’ll show you exactly how to recover sky detail and blend it seamlessly into your footage using Nano Banana and Premiere Pro.

Step 1: Grab a Reference Frame

Scrub through your footage until you find a frame where the blown-out area is clearly visible.

Export that frame as a PNG.

This single frame will be the base that Nano Banana uses to reconstruct the missing sky detail.

Step 2: Rebuild the Sky with AI

Head over to Nano Banana and upload your PNG.

Here’s a simple prompt you can use (tuned for best results):

> Prompt:

Recover sky details: reduce blown highlights, reconstruct clouds and texture, preserve original perspective and lighting, do not alter foreground subjects, output a photorealistic high-resolution PNG that blends naturally with the original frame.

Download your repaired plate once Nano Banana does its magic.

Step 3: Composite in Premiere Pro

Now it’s time to blend the repaired sky back into your video.

1. Place the repaired plate on a track above your original clip.

2. Use the Opacity Pen tool to draw a mask around the sky.

3. Feather the mask generously — start around 40px and adjust as needed.

4. Lower the repaired plate’s opacity to about 90%.

5. Use Lumetri to make final color tweaks and ensure everything blends seamlessly.

Why This Works

Nano Banana isn’t just fixing colors — it’s rebuilding missing texture and detail in the highlights. By combining that reconstructed sky with simple compositing techniques, you create a natural, believable result without reshooting a single frame.
