Whether you are a seasoned Photoshop user or just starting to explore the capabilities of the software, this article will provide you with the knowledge and techniques to master the art of adding to a Pen selection and elevate your image editing skills.
Selecting a Pen Path
In Photoshop, the Pen tool is a versatile drawing tool that allows you to create precise paths and shapes. When you work with the Pen tool, you create a series of anchor points that define the shape of your path. You can then add or remove anchor points, or adjust their position, to refine the path’s shape.
Selecting a Pen Path
To select a pen path, follow these steps:
| Step | Action |
|---|---|
| 1 | Click on the Pen tool in the Tools panel. |
| 2 | Move the cursor to the desired starting point of the path on the canvas and click or drag to create the first anchor point. |
| 3 | To create additional anchor points, click or drag along the path. To create a straight line segment, click once to create an anchor point. To create a curved line segment, drag the cursor to create a direction line, then click to create the next anchor point. |
| 4 | To close the path, click on the first anchor point or double-click anywhere on the path. |
Once you have created a path, you can select it by clicking on it with the Pen tool selected. You can also select multiple paths by holding down the Shift key and clicking on them.
Adding Corner Points
Corner points are where the direction of the pen path changes abruptly. They are typically created when you click the mouse to add a new point to the path. You can also add corner points by dragging the pen tool along a path and clicking to add points where you want the direction to change.
To add a corner point:
1. Select the Pen tool from the Toolbar.
2. Click on the canvas to add the first point to the path.
3. Drag the Pen tool along the path and click to add additional points.
4. To create a corner point, click and drag the Pen tool away from the path and then release the mouse button. This will create a corner point where the mouse button was released.
The following table summarizes the different types of corner points that you can create:
| Corner Point Type | Description |
|---|---|
| Smooth | The path continues in the same direction as the previous segment. |
| Corner | The path changes direction sharply at the corner point. |
| Bezier | The path curves smoothly at the corner point. |
You can change the type of corner point by clicking on the corner point with the Direct Selection tool and then selecting the desired type from the Options bar.
Using the Add to Selection Tool
Photoshop’s Add to Selection tool, located under the Select menu or by pressing the Shift + A keys, is a versatile tool that enables you to expand or refine your existing selections. Here’s a detailed step-by-step guide to using it effectively:
Step 1: Create an Initial Selection
Begin by making an initial selection using any of Photoshop’s selection tools, such as the Rectangular Marquee Tool or the Lasso Tool. This selection will serve as the starting point for adding additional areas.
Step 2: Activate the Add to Selection Tool
Navigate to the Select menu and choose Add to Selection. Alternatively, press Shift + A to activate the tool.
Step 3: Define the Expansion Area
With the Add to Selection Tool selected, click and drag the cursor over the areas you wish to add to the existing selection. The current selection boundary will expand accordingly. You can adjust the feather radius and anti-aliasing settings in the Options bar if needed.
Step 4: Handle Intersections
When adding new areas to a selection, Photoshop offers three options for handling intersections:
| Option | Effect |
|---|---|
| Add | Expands the selection to include the intersecting areas. |
| Subtract | Removes the intersecting areas from the current selection. |
| Intersect | Limits the selection to the areas that overlap with both the previous and current selections. |
Step 5: Use Multiple Intersections
You can create complex selections by performing multiple Add to Selections with different intersection options. For example, you could subtract an area from a primary selection while adding another area back in.
Step 6: Refinement and Precision
The Add to Selection Tool provides several options for refining and improving the precision of your selection:
- **Feather Radius**: Blurs the edges of the selection to smooth the transition.
- **Anti-aliasing**: Reduces jagged edges by creating a smoother, more gradual transition between pixels.
- **Refine Edge**: Opens a dedicated dialog box for fine-tuning the selection boundaries using advanced options such as Smart Radius and Edge Shift.
Combining Pen Paths
Merging Pen Paths
To merge multiple pen paths into a single path, select the paths you want to combine using the Shift or Ctrl key. Then, right-click and select “Merge Shapes > Merge” from the context menu.
Uniting Pen Paths
Combining paths with “Unite” creates a new path that includes the union of the selected paths. Non-overlapping areas of the paths will be combined, while overlapping areas will intersect or be eliminated depending on the settings in the “Unite Options” dialog box.
Subtracting Pen Paths
Subtracting combines selected paths into a new path by removing the areas where they overlap. To subtract, select the paths, right-click, and choose “Merge Shapes > Subtract Front Shape” or “Subtract Back Shape.”
Intersecting Pen Paths
Intersecting combines paths to create a new path that includes only the areas where they overlap. To intersect, select the paths, right-click, and choose “Merge Shapes > Intersect.”
Excluding Pen Paths
Excluding combines paths to create a new path that includes the areas where they don’t overlap. To exclude, select the paths, right-click, and choose “Merge Shapes > Exclude.”
Merge Options
| Option | Description |
|---|---|
| Fill Rule | Determines how overlapping areas are handled (Non-Zero Winding, Even-Odd Winding) |
| Anti-alias | Smooths the edges of the merged paths |
| Tolerance | Adjusts the level of tolerance for merging paths |
Excluding Areas from a Pen Selection
To exclude specific areas from your Pen selection, follow these steps:
- Activate the Subtract from Selection Mode: Hold down the Option (Mac) / Alt (Windows) key to enable this mode.
- Draw Over the Areas to Exclude: Using the Pen tool, draw over the areas you want to remove from the selection.
- Release the Option/Alt Key: Once you have drawn over all the areas to exclude, release the Option/Alt key to return to the normal Pen tool mode.
- Continue Creating Your Selection: You can now continue drawing the outline of your selection around the excluded areas.
- Refine Your Selection (Optional): Use the Direct Selection tool (A) to adjust individual anchor points or segments of the selection as needed.
- Make the Selection: Once you are satisfied with the excluded areas and the overall shape of your selection, click the “Make Selection” button in the Options bar.
- Invert the Selection (Optional): If you want to select everything outside of the excluded areas, go to Select > Inverse (Shift+Ctrl/Cmd+I) to invert the selection.
- Modify the Selection Border (Optional): In the Options bar, under the “Pen Tool” settings, adjust the “Border” value to control the width of the selection border.
By following these steps, you can easily exclude specific areas from your Pen selection, giving you greater control over the selection process.
| Keyboard Shortcut | Action |
|---|---|
| Option (Mac) / Alt (Windows) + Click | Activate Subtract from Selection Mode |
| Option (Mac) / Alt (Windows) + Release | Return to normal Pen tool mode |
| Shift+Ctrl/Cmd+I | Invert the selection |
Rasterizing a Pen Path
Rasterizing a pen path converts the vector shape into a raster image, which consists of pixels. This allows you to edit and manipulate the shape using the standard editing tools in Photoshop, such as brushes, erasers, and filters. Rasterizing a pen path is a permanent action, and the vector path information will be lost.
Steps to Rasterize a Pen Path:
- Select the pen path you want to rasterize.
- In the Layers panel, right-click on the path layer and select "Rasterize Layer."
- In the Rasterize Layer dialog box, set the following options:
- Resolution: Specify the resolution of the rasterized image in pixels per inch (ppi). A higher resolution will produce a sharper image, but it will also increase the file size.
- Anti-aliased: Enable this option to smooth the edges of the rasterized image and reduce pixelation.
- Scale: Select "Use Path Size" to create a rasterized image that matches the size of the path. You can also specify a custom scale factor.
- Click "OK" to rasterize the pen path.
Benefits of Rasterizing a Pen Path:
- Allows you to edit the path using pixel-based tools.
- Can improve the appearance of the path in some cases, such as when using brushes or filters.
- Makes the path resistant to scaling and distortion.
Considerations when Rasterizing a Pen Path:
- Rasterizing a pen path is a permanent action.
- The vector path information will be lost, so you will no longer be able to edit the path as a vector object.
- Rasterizing a large path can significantly increase the file size.
Creating a Vector Mask from a Pen Selection
Method
-
With the Pen Tool selected, create a shape around the area you want to add to the selection.
-
Once the shape is complete, right-click (Win) or Control-click (Mac) on it and choose "Make Selection" from the menu.
-
In the "Make Selection" dialog box, adjust the settings as follows:
- Feather: 0px (to create a hard edge)
- Anti-alias: Checked
- Invert: Unchecked
-
Click "OK" to apply the selection.
-
With the selection active, return to the Pen Tool ("P") and click on the Add to Selection icon in the options bar.
-
Draw another shape to add to the selection.
-
Repeat steps 3-6 as necessary to add multiple shapes to the selection.
-
To subtract shapes from the selection, hold down the Alt (Win) or Option (Mac) key while drawing with the Pen Tool.
-
To intersect shapes with the selection, hold down both the Shift and Alt (Win) or Option (Mac) keys while drawing with the Pen Tool.
-
Adjusting the Pen Tool Settings for Enhanced Precision
To achieve even greater precision when creating a vector mask from a pen selection, consider the following settings in the Pen Tool options bar:
- Pen Pressure: Enables pressure-sensitive drawing for more natural curves and smoother transitions.
- Smoothing: Reduces jitters and smooths out the path created by the Pen Tool, especially useful for creating flowing lines.
- Fidelity: Sets the threshold for curve interpolation, higher values produce smoother curves with fewer anchor points.
- Angle: Controls the angle tolerance for curves, higher values result in straighter lines and sharper angles.
- Snap to Other Paths: Automatically aligns your path to existing vector shapes or pixels in the image, ensuring accurate alignment and eliminating guesswork.
