Photoshop Generative Fill Done Right: Steps, Prompts and Fixes

Clients now expect fast photo fixes: a product shot with the background extended for a banner, a wire removed from a shop photo, an empty table filled for a menu card. Studios in Delhi expect a new designer to do this in minutes, not hours. One Delhi job post this week asked a fresher to make product mockups and AI product images with Photoshop, Illustrator, ChatGPT and Gemini^[4].

The catch is quality. A careless fill looks fine on a phone and falls apart on a printed banner. Knowing where the tool is weak is what separates a trained designer from someone pressing a button.

1. 1
   Open the image

   Choose File > Open and pick your photo^[1].

2. 2
   Select the area

   Use a selection tool such as the Lasso or the Selection Brush to mark what you want to change^[1]. Leave a little room around the object so the new pixels blend.

3. 3
   Click Generative Fill

   It appears in the Contextual Task Bar once you have a selection^[1].

4. 4
   Pick a model

   Use the model picker in the Contextual Task Bar. Adobe lists its Firefly models (Firefly Fill & Expand, Firefly Image 5, Firefly Image 1) and partner models such as FLUX and Gemini^[1].

5. 5
   Write a prompt or leave it blank

   Describe what to add in plain words, or leave the box empty to let Photoshop fill the selection from the surrounding pixels^[1].

6. 6
   Generate and choose

   Click Generate and pick the best variation in the Properties panel^[1]. Each Generate creates a new Generative Layer^[2].

Short, concrete prompts work best. Describe the thing, not the whole picture. Photoshop already sees the rest of the image.

• No selection: the Generative Fill button appears in the Contextual Task Bar after you select an area^[1].
• No internet: generative AI features in Photoshop need an internet connection^[2].
• Plan or region: they are available to Photoshop subscribers and trial users wherever Adobe provides services but not to users in China^[2].
• Credits: each generation uses generative credits. You can see your balance in the Account menu in Photoshop^[2][3].
• Old version: update Photoshop from the Creative Cloud app. Adobe also retires older partner models from time to time, so a model you used last month may disappear from the picker^[1].
• Soft result: Adobe's FAQ says the Firefly model returns output of 1024 x 1024 pixels^[2], so a very large selection can look soft. Fill smaller areas or try Enhance Detail.

1. 1
   Zoom to 100%

   Check edges, hands, faces, text and repeating patterns. AI often adds extra fingers or melted letters.

2. 2
   Fix with masks

   Paint on the Generative Layer's mask to blend edges. Use Clone Stamp or Spot Healing for small faults.

3. 3
   Match light and colour

   Add a Curves or Hue/Saturation adjustment layer clipped to the new area so it matches the photo.

4. 4
   Save as PSD

   Keep every Generative Layer editable^[2]. Export JPG or PNG only for delivery.

• Product banner set: one square product photo extended into a 1200 x 628 web banner, a 1080 x 1920 story and a wide shop-front print, each finished by hand.
• Clean-up before and after: five real-estate or shop photos with wires, clutter and signs removed, shown side by side.
• Menu card: food photos with backgrounds extended and props added, laid out in InDesign or Illustrator.

Worked example (hypothetical): a sweet shop owner sends a phone photo of one gift box on a cluttered counter. You remove the clutter with a blank-prompt fill, extend the canvas for a Diwali banner, add "marigold flowers around the box" in a small selection, fix the edges with a mask and match the colour with Curves. Twenty minutes, one banner and a matching Instagram post. For more on design work for shops, see graphic design for small business owners.

Generative Fill is one tool. In June 2026 Adobe opened an AI assistant (public beta) in Photoshop that carries out described changes across a composite, such as replacing a background, resizing assets for different platforms and tidying layers^[5]. Designers now use both, with chat tools like ChatGPT or Gemini for ideas.

What the human still decides: the idea, what stays real in a product photo, whether a result is honest to show a customer and whether it will print well. CABA's courses now teach AI and agentic AI workflows inside the curriculum, with the designer checking every pixel before delivery. For the wider picture, read graphic design with AI.

Generative Fill is easy to start and hard to finish well. In a 1-to-1 class the trainer looks at your result at 100% and shows you the edge, shadow or colour you missed, on your own project. That habit of checking is what clients pay for.
