Step 1: Open Your Image and Extend the Canvas

1. Open Photoshop and load your image (File > Open).
2. Select the Crop Tool (C).
3. Drag the crop handles outward to expand the canvas.
   • For precise sizing, enter dimensions in the top toolbar (e.g., 1920×1080 pixels).
4. Click ✓ to confirm.

Pro Tip: Use a solid-colored background (like white) initially for easier editing.

Step 2: Use Content-Aware Fill for Simple Backgrounds

Best for: Solid colors, subtle gradients, or simple textures (e.g., walls, skies).

1. Select the empty area with the Rectangular Marquee Tool (M).
2. Press Shift+Backspace (Windows) or Shift+Delete (Mac).
3. Choose Content-Aware from the dropdown menu.
4. Click OK.

Photoshop auto-fills the space by sampling nearby pixels.

Troubleshooting:

• If edges look messy, refine the selection with Select > Modify > Feather (1-2 pixels).
• For patterns (e.g., grass), skip to Step 4.

Step 3: Clone Stamp Tool for Detailed Textures

Best for: Complex backgrounds (e.g., forests, crowds, brick walls).

1. Select the Clone Stamp Tool (S).
2. Hold Alt (Windows) or Option (Mac) and click to sample a source area.
3. Paint over the empty canvas to replicate the texture.

Pro Settings:

• Brush Hardness: 30-50% for soft edges.
• Opacity: 70-80% to blend naturally.

Example: Extend a forest by cloning trees and foliage.

Step 4: Use Generative Fill for Realistic Results

Best for: Photorealistic extensions (e.g., beaches, skies, streets).

1. Select the empty area with the Lasso Tool (L).
2. Click the Generative Fill button in the taskbar.
3. Leave the prompt blank or describe the scene (e.g., “sandy beach”).
4. Click Generate.

Photoshop AI creates up to 3 variations. Pick the best match.

Pro Tip: For better accuracy, sample part of the background and include it in the selection.

Step 5: Blend Edges Seamlessly

1. Add a Layer Mask to the extended area (click the mask icon in the Layers Panel).
2. Select the Brush Tool (B) with black as the foreground color.
3. Softly paint along harsh edges to blend them.

Advanced Fix:

• Use Filter > Blur > Gaussian Blur (1-2px) to soften mismatched textures.
• Adjust Brightness/Contrast (Image > Adjustments) to match lighting.

Step 6: Correct Perspective Distortion

For architectural or angled backgrounds:

1. Go to Edit > Perspective Warp.
2. Draw grids along the existing background (e.g., walls, roads).
3. Drag anchor points to align the extended area.
4. Click Warp and fine-tune.

Step 7: Save and Export

1. Save as PSD: Retain layers for future edits (File > Save As).
2. Export:
   • Web: File > Export > Save for Web (choose JPG/PNG).
   • Print: File > Export > Export As (TIFF, 300 DPI).

Common Mistakes to Avoid

1. Ignoring Resolution: Extending a low-res image causes pixelation.
2. Overusing Generative Fill: It can create unrealistic artifacts. Always review results.
3. Mismatched Lighting: Use Curves or Color Balance to harmonize tones.
