How to Create a Mockup in Photoshop – Day 26

Create a Mockup That Inherits the Photograph’s Own Light

When you create a mockup you are asking a flat graphic to pretend it exists inside a photograph, and there are only two ways it gives itself away: the perspective is wrong, or the lighting is. Perspective is the easy half — a Smart Object and a free transform settle it in about a minute.

Lighting is where most mockups fail, and the fix is smarter than painting shadows by hand. The billboard, the poster, the shop sign already has highlights, shadows and grime in the original photograph. Rather than inventing that lighting, you borrow it back with Apply Image and let it fall onto your design.

The Three Phases

Clear the Existing Graphic

The Remove Tool with Generative AI wipes the surface you’re going to fill, so you’re placing your design on a clean plate rather than trying to cover something.

Place It as a Smart Object

Smart Objects are what make a mockup worth building: the design stays editable forever, and the perspective transform is non-destructive.

Borrow the Original Lighting Back

Apply Image copies the photograph’s own light onto a layer clipped to your design. This is the step that turns a flat rectangle into something that looks photographed.

Clear the Surface First

1. Select the Remove Tool and Check Your Settings

   Generative AI on, “Remove after each stroke” unchecked, “Create new layer” checked. That last one keeps the removal off your background so you can undo it later without starting over.

2. Paint Over Whatever Is Already There

   Existing text, a poster, a logo — brush across all of it, then click the checkmark and let it generate once. Doing it in a single pass rather than stroke by stroke gives the model the whole area to reason about.

3. Rough Out the Shape With the Polygonal Lasso

   Approximate the billboard or panel you’re filling. This is only a guide for size — it doesn’t need to be exact.

   

4. Fill a New Layer With White, Then Draw a True Rectangle Over It

   Use the Rectangular Marquee. This matters: your design has to start as a perfect rectangle, because you’re going to distort it into perspective deliberately. Starting from an already-skewed shape means compounding two distortions.

5. Delete the Rough Layer and Convert the Rectangle to a Smart Object

   Layer > Smart Objects > Convert to Smart Object.

6. Free Transform and Drag the Corners Independently

   Cmd/Ctrl + T, then hold Cmd/Ctrl while dragging each corner. That modifier is what unlocks corner-by-corner distortion, and it’s how you match the perspective of the wall or sign in the photograph.

   

Borrow the Lighting Instead of Painting It

7. Hide the Smart Object for a Moment

   You need to see the original surface underneath, because that’s what you’re about to copy.

8. Add a New Layer and Run Image > Apply Image

   This bakes a flattened copy of the visible photograph — including every highlight, shadow and stain on that surface — onto the new layer.

   

9. Clip That Layer to Your Smart Object

   Hold Alt/Option and click between the two layers. The borrowed lighting now applies only to your design and nowhere else.

10. Set the Clipped Layer to Soft Light

    Make the Smart Object visible again. Soft Light keeps the tonal variation and drops the flat colour, so the photograph’s light lands on your graphic without repainting it.

11. Fine-Tune With Levels

    Cmd/Ctrl + L on the clipped layer to push the borrowed shadows and highlights harder or pull them back. This is the dial that decides how weathered the surface looks.

Where Mockups Give Themselves Away

Five failures account for almost every mockup that doesn’t convince, and none of them are about the design itself.

The Graphic Is Perfectly Clean

Real surfaces are never evenly lit. If your design has no variation across it at all, the Apply Image step was skipped or the opacity is too low.

The Perspective Is Nearly Right

Nearly is worse than obviously wrong — it reads as uncanny. Match the corners to real lines in the photograph, not to your eye.

It Was Placed as a Flat Layer

No Smart Object means every revision starts over, and every transform degrades the pixels.

The Old Graphic Is Still Showing Through

Covering isn’t removing. Clear the surface properly first, or the ghost of the original text will sit under yours.

The Edges Are Too Sharp

A printed graphic on a real surface picks up the same slight softness as everything else in the frame.

Why the Smart Object Is the Whole Point

Double-click the Smart Object’s thumbnail and it opens in its own window as a flat, undistorted document. Edit the design there, save, and the mockup updates with the perspective and the borrowed lighting already applied.

That’s what separates a mockup from a one-off composite. A client asks for a different colour, a bigger logo, a new strapline — and you change it in the 2D file rather than rebuilding the perspective every time. Create a mockup properly once and it becomes a template you can point at any design for the rest of the project. Replacing a sign is the same technique on a smaller surface.

Build One Mockup Today

Find a photograph with a flat surface in it — a billboard, a shop window, a laptop screen. Clear it with the Remove Tool, draw a true rectangle, convert to a Smart Object and Cmd/Ctrl-drag the corners into perspective. Then hide it, Apply Image, clip, set to Soft Light and bring it back.
