ON1 Resize AI 2022.5 is a professional-grade image lossless enlargement software designed specifically for macOS. Its core is based on the industry-leading Genuine Fractals technology and incorporates artificial intelligence (AI)-driven algorithms, aiming to enlarge digital photos to massive sizes while maintaining impressive clarity, detail, and image quality. It can run as a standalone application or be seamlessly integrated as a plugin into Adobe Photoshop and Lightroom. This article will provide you with a detailed operation guide, from the core interface to the complete workflow.
I. Detailed Explanation of the Core Interface and Workspace
After launching ON1 Resize AI, you will see a main interface with a clear layout and well-defined functional areas. The main workspace can be divided into the following parts:
- Top Menu Bar: Contains all advanced commands, such as File, Edit, View, Adjust, and Help.
- Left Panel Area:
- Folder Browser (Browse): Used to navigate and select image folders on local disks.
- Preview Navigator (Navigator): Displays a thumbnail of the entire image; the area within the red box represents the portion currently displayed in the main preview area, and can be dragged to quickly reposition.
- Presets Panel (Presets): Provides a large number of predefined output size and sharpening presets, such as “Poster Size,” “Canvas Print,” “Commercial Advertising,” etc., which can be applied with one click.
- Central Preview Area: The core area of the software, displayed by default in “Split View.” The left side shows the “original” image, and the right side shows the “processed” image with enlargement and adjustment effects applied. You can switch to single view mode via the View menu.
- Right Panel Area: All core adjustment functions are centralized here.
- Adjust: Contains two core modules: “AI Enlarge” and “Sharpen.”
- AI Enlarge Panel: Set the target size here (dimensions, resolution, units) and select the AI enlargement algorithm (such as “Perfect Resize” or “AI Mode”).
- Sharpen Panel: Provides “Standard Sharpen” and “Output Sharpen” options to restore or enhance details after enlargement.
- Metadata: View and edit image information such as EXIF data.
- Bottom Status Bar & Toolbar: Displays information such as the current image’s zoom ratio and pixel dimensions. The toolbar provides practical tools such as the “Pan Tool,” “Zoom Tool,” and “Split View Comparison Tool.”
II. Complete Workflow: From Opening to Exporting
1. Create/Open a Project
Method 1: Open via “File Browser”
- In the left panel, click the “Browse” tab.
- Navigate to the folder where your image is located.
- Double-click the target image thumbnail, or drag it to the central preview area.
Method 2: Open via the menu bar
- Click the menu bar “File” > “Open…”.
- Or use the shortcut
Command (⌘) + O. - In the system dialog, select the image file and click “Open”.
2. Set enlargement parameters and AI processing
- In the right panel, make sure the “AI Enlarge” subpanel under the “Adjust” tab is selected.
- In the “Size” section, set your target output dimensions.
- You can enter specific width and height values (units can be pixels, inches, centimeters, etc.).
- Or scale by percentage (e.g., 200%, 400%).
- Check “Lock aspect ratio” to maintain the original image proportions.
- In the “Resolution” field, enter the target print resolution (usually 300 PPI).
- In the “Method” drop-down menu, select an AI enlargement algorithm. It is recommended to try “AI Model”, which has better detail reconstruction capabilities for different types of images (such as people, landscapes, and architecture).
Tip: The software processes in real time and displays the result in the “After” preview on the right. You can use the zoom tool (shortcut Z) to zoom in and examine detail differences at 100% view.
3. Apply Sharpening and Fine-Tune
- In the right panel, click the “Sharpen” sub-panel.
- Typically, applying moderate sharpening after upscaling can compensate for detail. Adjust the “Amount”, “Radius”, and “Detail” sliders.
- Use the “Masking” slider (hold the
Option (⌥)key while dragging to preview the mask area; white indicates where sharpening is applied) to control the areas where sharpening is applied, avoiding noise in smooth areas (such as the sky).
4. Export the Final Image
- After completing all adjustments, click the menu bar “File” > “Export…”.
- Or use the shortcut
Command (⌘) + E. - In the export dialog that appears:
- Set the Export To location for the output file.
- Specify the file Format, such as TIFF, JPEG, or PNG. For high-quality printing, the lossless TIFF format is recommended.
- Configure format-related options (such as JPEG quality and TIFF compression).
- You can rename the file and set the color space.
- Click the “Export” button in the lower right corner of the dialog box to save the final image.
III. Advanced Tips for Common Features
1. Batch Processing
In the “Browse” panel, hold down the Command (⌘) key and click to select multiple images, then right-click and choose “Add to Batch List.” In the batch processing bar activated at the bottom, set uniform output dimensions, sharpening parameters, and export settings, then click “Run” to process all images at once, greatly improving work efficiency.
2. Integrated Workflow with Photoshop/Lightroom
When used as a plug-in, after opening an image in Photoshop, click “Filter” > “ON1” > “Resize AI 2022.5”. After making adjustments, click the “Apply” button in the lower right corner of the interface. The processed image will be returned to Photoshop as a new smart object layer, maintaining flexibility for further editing.
3. Use Presets to Quickly Apply Common Dimensions
For commonly used standard output dimensions (such as 8×10 inches, 16×20 inches), there is no need to enter them manually. In the “Presets” panel on the left, find the preset under the corresponding category (such as “Standard Photo Sizes”) and double-click to apply all dimensions and recommended sharpening settings with one click.
IV. Common Problems and Solutions
Problem 1: After processing, halos or artifacts appear at the edges of the image.
Solution: This may be caused by excessive sharpening. Return to the “Sharpening” panel and reduce the “Amount” and “Radius” values. More importantly, increase the “Masking” value so that sharpening is only applied to edges and textured areas.
Problem 2: After enlarging, unnatural textures or noise appear on skin or smooth areas.
Solution: Try switching between different “Methods” in the “AI Enlarge” panel. For portraits, you can try the “Perfect Resolution” algorithm. Also, in the sharpening step, make sure to use sufficient masking to protect smooth areas.
Problem 3: The software processes slowly, especially with large images.
Solution: AI enlargement is a computationally intensive task. Please make sure to close other large applications. You can check whether GPU acceleration is enabled (if your Mac has a discrete graphics card) in the menu bar under “ON1 Resize AI” > “Preferences” > “Performance”. Appropriately lowering the preview resolution (switch in the toolbar below the preview area) can also improve interaction smoothness.
