How to prepare images

Whether it’s stock photos, 3D assets, or Gen AI, the way you edit and compose them is the same. So let’s jump right into preparing the images.

While I don’t recommend using Generative AI to make creative decisions, I do use Adobe Firefly’s Generative Fill tool when I want to enlarge images and remove unwanted objects.

How to Expand Images with Generative Fill in Photoshop

Using this image as an example, I’ll show you how to use Photoshop’s generative fill.

1. Select the Rectangular Marquee tool

Click and drag to select the empty part of the canvas and some of the existing sky. You will notice that the floating context bar below the image changes because we have an active selection.

2. Click on Generative Fill

If you want, you can fill in a prompt that tells you what to generate, but in this case we just want to fill the gap and expand the sky, so we don’t need to do that.

3. Click on “Generate”

Photoshop uses the existing pixels to fill in and generate the three variations shown in the image. Properties panel. Since this is a simple sky, the variations are more or less the same, so just pick one and voila! The sky is filled in.
