How to Upscale Images with Preserve Details 2.0

Preserve Details 2.0 is an advanced, machine-learning-assisted interpolation algorithm in Adobe Photoshop designed to upscale images without losing edge sharpness or critical texture. This guide explains how to enable the feature, apply it using the Image Size tool, and fine-tune its noise reduction slider to achieve optimal enlargement results for low-resolution graphics and photographs.

Enabling the Feature

In most modern versions of Adobe Photoshop, Preserve Details 2.0 is enabled by default. If it does not appear in your options, enable it through preferences:

  1. Open Photoshop and navigate to Edit > Preferences > Technology Previews (on macOS, Photoshop > Preferences > Technology Previews).
  2. Check the box for Enable Preserve Details 2.0 Upscale.
  3. Click OK and restart Photoshop if prompted.

Step-by-Step Guide to Upscaling

Once enabled, you can upscale your image using the standard image resizing menu.

  1. Open the Image: Launch Photoshop and open the image you want to enlarge.
  2. Access the Image Size Menu: Navigate to the top menu bar and select Image > Image Size, or use the keyboard shortcut Ctrl + Alt + I (Windows) or Cmd + Option + I (macOS).
  3. Set New Dimensions: Choose your preferred measurement unit (Pixels, Inches, or Percent) and enter your desired target size or resolution. Ensure the chain-link icon between Width and Height is selected to maintain the aspect ratio.
  4. Choose Resampling Method: Click the Resample dropdown menu and select Preserve Details 2.0.
  5. Adjust Noise Reduction: A Reduce Noise slider will appear below the resample selection.
    • Low Values (0%–30%): Preserves maximum texture, fine lines, and original grain, but may exaggerate digital noise or compression artifacts.
    • High Values (70%–100%): Smooths out digital noise, but risks making surfaces look plastic or overly soft.
    • Balanced Approach: Use the preview window on the left side of the dialog to zoom in on complex areas (such as eyes, hair, or textured fabrics) and set the slider between 40% and 60% for standard photographs.
  6. Apply the Changes: Click OK to process the image. The algorithm will generate the additional pixels using deep-learning prediction to keep boundaries and textures crisp.
