Adapt a Spec Ad Visual to a New Format with Photoshop's Generative Fill and Expand

What This Does

Takes one spec ad visual, a product photo or a client's existing image, and reshapes it to fit a second ad format. A billboard's wide canvas instead of a print page is a common swap, and it happens without a redesign from scratch or a request to the production team.

Before You Start

• Access to Photoshop with Adobe's generative AI features. These draw on a generative credit allowance tied to your Creative Cloud plan, so check helpx.adobe.com or your account page for your current balance before a large expand
• The client's original photo or logo, and the client's permission to use it in a mockup you plan to show them
• The target format's dimensions: a billboard's wide aspect ratio, a specific digital banner size, or whatever the second placement needs

Steps

1. Find the AI feature

Open the spec ad's image in Photoshop. Adobe's generative tools show up as options in the toolbar and in a floating menu that appears once you make a selection or resize the canvas. Look for wording like Generative Fill or Generative Expand near the selection tools. If your version labels things differently, look for an AI or Firefly-branded icon in the same area.

2. Tell it what you need

To resize the ad for a new format, adjust the canvas to the new dimensions first. Then use the expand option to fill the new space. To swap out or extend part of the image itself, a background, say, select the area and describe what should appear there, or leave the description blank and let it match the surrounding image. Generate a few variations and pick the one that reads well at the new size.

3. Review and use the result

Look closely at the generated area for anything that reads as obviously synthetic: odd text, a distorted edge, a repeated pattern. Catch that before it reaches a pitch. Label the mockup clearly as a concept when you show or send it to the client, since a generated background, product, or storefront is not a real photo of theirs. If the original image carried the client's real logo or photo, confirm you have their permission to use it in this new version before it leaves your own file.

Real Example

Scenario: A print spec ad for a furniture store's Labor Day sale already exists as a half-page layout, and the pitch also calls for a wide-format billboard version of the same visual.

What you type/do: Open the print ad's product photo in Photoshop, resize the canvas to the billboard's wide dimensions, and use the expand tool to fill the new width around the existing product shot. Generate two or three variations of the extended background.

What you get: A billboard-shaped version of the same product photo with a plausible extended background, ready for headline text and a concept label for the pitch.

Tips

• Treat every result as a pitch mockup, not a finished ad. The station's production and creative staff still produce anything that actually runs.
• Watch your generative credit balance when adapting several visuals in one sitting. Running out mid-project means waiting on a plan refresh or an upgrade.
• A billboard headline still needs to land in seven words or fewer once you add text. Leave room for it in the expanded canvas.

Tool interfaces change. If a button has moved, look for similar AI/magic/smart options in the same menu area.
