Generative Fill only works in Photoshop beta, at the time of this writing. Here’s how to get it:

Installing Photoshop Beta

Go to your Creative Cloud. Make sure you have a valid Creative Cloud account and sign in.

Go to updates, choose check for updates. This will ping the server, make sure you get the very latest version.

Then go under beta apps. I’ve already installed mine, but you’ll see an install like this. Click install. If you have previously installed the beta, click update here and you should be on Photoshop version 24.6.0. Make sure you have a current subscription. If you have CS6, this won’t work. I’m sorry.

Let’s start with something not as crazy, and we’re going to go down the rabbit hole from here.

Extending a Photo, uncropping

How many times have you shot a photograph and then afterwards you realize, Hey, I wish I’d gone a little bit wider.

Grab the crop tool. Let’s drag it out, make it a little bit bigger.

Make a selection with the rectangular marquee tool.

Press Generative Fill.

Hit Generate.

Adobe sensei uses AI to build the rest of this image, as if I had shot it wider. Pretty amazing stuff.

Changing Object and generating clothing

Another quick example.

With the Lasso tool, make a quick selection.

Hit Generative Fill, and this time, type into the field.  Red T shirt and bingo.

Replacing a background

Let’s replace the background. We’re going to grab a Lasso tool and we’re going to make a rough selection around that background. I’m making a really rough selection just to show you how well this works. In fact, you don’t want it too tight. You want to give it some room.

Now, we’re going to hit Generate a fill. And why don’t we put in city? Hit Generate.

And we actually get three options in the Properties panel.

Each time we regenerate or change the prompt, it creates three more images. Choose the one you want to use.

Advanced Clothing change

This is the image I started with. Let’s give her some jeans instead of the skirt.

Make a selection with the lasso tool. (Watch this tip to see how important selections are, and how to make the right type of selections for better results in Generative Fill)

Hit Generative Fill, type in jeans. Let’s look at variations.

To view the variations, We can either view the thumbnails in the info panel. or click the arrows in the toolbar. See this tutorial on mixing variations

These are brand new images that never existed before. Let me show you. Why don’t we change this jacket to a plaid shirt?

Make a selection with the lasso tool

Type in plaid shirt. And look at that.

Some of the results you get here are not always perfect.

We could change this to something else, say a tank top. This one is looking pretty realistic. I mean, look at the arms and the shirt. Look how it’s even made the area for the sleeves and everything.

It has given us some extra hair. These are certainly, lots of bugs to fix and improvements to be made. If history of other Generative Models like Mid Journey  are anything to go by, these  improvements will happen very fast.

Extend a street

Let’s look at one more example.

So let’s grab our crop tool, let’s extend this.

Now, we want to extend the street, so let’s grab the Rectangular Marquee tool,

Choose Generative Fill in the toolbar. Remember, if you just want to extend and you don’t want to add anything, don’t fill out any prompts here and just hit Generate

.And look at that. That’s pretty amazing if you ask me.

Where do the images come from?

So where are these images coming from? These images have never existed before. They’re actually being generated by the AI.

What the AI is doing is it’s actually looking at the image and analyzing and knowing what it is. Now, Adobe didn’t just start with this last week. Adobe has actually been developing Adobe sensei for 10 years. So it’s actually had a little bit of training already on all the selections and different things that we’ve been doing throughout the years with the sensei tools. Firefly (name of the generative part of Sensei) Is looking at all the photographs inside of Adobe stock, and then it’s taking what it’s learning, and then it’s recreating these images or these parts of images from nothing. So it’s creating images that never existed before. Adobe have said they are going to find a way to compensate the contributors of Adobe stock. We will see what they decide to do.

I’m going to do a series on here where I’m going to go more in-depth and I’m going to show you more of the features and more things you can do.

  1. Fantastic Colin but as a camera club member how will we know if images are created or taken in club competitions?

  2. It looks sort of convincing, but I have to say, on a closer look, the problems stand out. No shadows on the dogs for instance which would actually place them in the location. You pointed out the flaws with the limbs on the female model. And the satellite dish looked simply fake – the lighting bore no relation to the background. I found the same thing was true with the colorize filter as well – that the filter never does find the edges of clothing, thus, a jacket will start blue, and then devolve into browns and umbers because the AI mistakes changes in shade and tone for object edges. It apparently has no way to tell what different items of clothing really are and how the bodies underneath them distort the cloth. Plus, whoever designed the colorize filter only offers a variety of faded “retro” choices, which is annoying and rather silly. So I will hold my breath with the AI fill-in feature. Fascinating, but flawed.

  3. Forget the issue of club competitions. Imagine the ramifications of AI generating pictures that can be used to blackmail someone. If you can change a jacket to a shirt can you have AI remove the shirt completely and create nude photographs of someone famous or otherwise. The statement, that who will you believe them or your own eyes is going to be rendored moot as you can no longer believe your own eyes.
