Super PhotoCut Pro is an intelligent image cutout and background processing software designed specifically for macOS. It utilizes advanced AI algorithms to help users quickly and accurately separate subjects from complex backgrounds, making it suitable for e-commerce, graphic design, photography post-processing, and many other scenarios. Its core advantages lie in intuitive operation, fast processing speed, and good retention of details such as hair and transparent objects.

I. Detailed Explanation of the Core Interface and Workspace

After launching the software, the main interface is mainly divided into the following functional areas:

Top Menu Bar and Toolbar: Includes file operations (new, open, save), view controls, selection tools (smart selection brush, erase brush, keep brush, eraser, etc.), processing buttons, and background setting options.
Left Preview and Tool Panel: Usually displays the original image. Below the selection tools, there are sliders for adjusting parameters such as brush size, hardness, and opacity.
Central Main Canvas: This is the core work area, used to display the image currently being edited. During the cutout process, selections and mask states are displayed with colored highlights (usually red/blue) or a transparent checkerboard background.
Right Properties/Background Panel:
- Background Editing: Provides solid color, gradient, and pattern fills, or import new images as backgrounds.
- Edge Refinement: Includes fine-tuning sliders for edge smoothing, feathering, shrink/expand, and more.
- Layers & History: Some versions support basic layer management and record operation steps for undo.

II. Complete Workflow from Creation to Export

Step 1: Create or Open a Project

Method 1: Create a New Project Click the menu bar File > Open Image... or use the shortcut ⌘Cmd + O. Select the image file you need to cut out from Finder and open it.

Method 2: Drag to Create Simply drag an image file from Finder onto the main software window or the Dock icon to open it quickly.

Step 2: Perform Smart Cutout

Mark Foreground and Background:
- Select the “Smart Select Brush” from the left toolbar (usually an icon with a brush tip and a + sign).
- Roughly paint over the interior of the subject, and the software will highlight the foreground it recognizes (the part to keep) in red.
- Switch to or select the “Erase Brush” (usually an icon with a brush tip and a – sign).
- Paint over the unwanted background areas, and the software will highlight the background to be removed in blue.
Automatic Processing: After marking a few strokes, the software usually calculates and displays a preliminary cutout result automatically (the background becomes transparent or a checkerboard pattern). If it doesn’t process automatically, click the “Process” button above the canvas.
Fine-tuning and Correction:
- Use the “Keep Brush” and “Eraser” to fine-tune areas where the automatic cutout is inaccurate.
- Zoom in on the canvas (⌘Cmd + +) for detailed retouching.
- Adjust the brush size on the left side (shortcuts: [ to decrease, ] to increase) to suit different areas.

Step 3: Edge Optimization and Detail Enhancement

Find the “Edge Optimization” or similar option group in the right panel:

Smooth: Eliminates jagged edges on the selection boundary, making transitions more natural.
Feather: Softens the edges to create a gradual fade effect; values are typically 1–5 pixels.
Contract/Expand: Shrinks or expands the selection boundary inward or outward, used to fix white edges or fill in gaps.
Smart Edge (if available): Performs enhanced calculations for complex edges such as hair and semi-transparent yarn.

As you adjust the parameters, the main canvas previews the effect in real time.

Step 4: Add or Change the Background

In the right panel, switch to the “Background” or “Background Edit” tab:

Solid Color Background: Click the color swatch and pick any color from the color picker.
Gradient/Pattern Background: Select the corresponding option and configure the colors and style.
Image Background: Click the “Add Image” or “Import” button and select a new image as the background. The new background layer will automatically be placed below the subject.
Adjust the Background: Select the background layer and use the transform tool (⌘Cmd + T) to scale and move it.

Step 5: Save and Export the Final Work

Click the menu bar File > Save or Export....

Save Project (⌘Cmd + S): Save as the software’s native format (e.g., .scp) so you can continue editing later.
Export Image (⌘Cmd + E or ⇧Shift + ⌘Cmd + S):
- In the pop-up window, choose the save location and file format (PNG is recommended to preserve a transparent background, or JPG for a non-transparent background).
- Set the image quality (for JPG) and resolution.
- After confirming, click “Export”.

III. Advanced Tips for Common Features

Quickly Invert Selection: If you have mistakenly marked the foreground and background, there is no need to erase and redraw. In the menu bar, find Select > Invert Selection (or use the shortcut ⇧Shift + ⌘Cmd + I) to swap the foreground and background markings.
Use the “Keep Brush” for Semi-Transparent Areas: For semi-transparent objects such as wedding veils, glass cups, and water splashes, use the “Keep Brush” at a lower opacity (adjustable in the left panel) and gently paint over them to better preserve their transparent texture.
Batch Processing Tips: Although the software is mainly designed for single-image processing, you can use “File” > “Batch Processing” (if available) or create a workflow using macOS “Automator” to quickly apply the same cutout settings to multiple images.
Flexible Rollback with History: Make good use of the “History” panel on the right. Clicking any step allows you to quickly revert to that state without affecting subsequent steps (more flexible than repeated undo).

IV. Common Problems and Solutions

Symptom	Possible Cause	Solution
After cutting out, there is residual noise or a white edge around the subject	1. Low color contrast between the original background and the subject, causing blurred AI recognition. 2. Improper edge feathering or contraction settings.	1. Use the “Erase Brush” to carefully clean the edge area, and appropriately contract the edge by 1-2 pixels. 2. Enable “Remove Noise Edge” or “Color Cleanup” in edge optimization (if available).
Fine details such as hair are cut off, making the result look stiff	The AI algorithm may misclassify fine hair as background.	1. Use a very fine “Keep Brush” (zoom in on the canvas) to carefully trace the hair edges. 2. Significantly increase the “Smart Edge” or “Hair Detail” optimization strength.
The software suddenly becomes slow or lags	1. The resolution of the image being processed is too high. 2. Too much software cache.	1. For web use, first reduce the long edge of the image to within 2000 pixels in software such as Photoshop before importing. 2. Try restarting the software. Check whether there is an option to clear the cache in “Preferences”.
Unable to export PNG images with a transparent background	1. PNG format was not selected during export. 2. The current canvas has a non-transparent background layer.	1. Be sure to select “PNG” format when exporting. 2. Before exporting, set the background to “None” or “Transparent” in the background panel on the right.
Keyboard shortcuts do not work	They may conflict with system or other application shortcuts.	1. Check whether there are custom options in the software’s “Preferences” or “Shortcuts” settings. 2. Temporarily close other software that may have global shortcuts (such as input methods and translation software).
