Creating a selection clipping path in Photoshop involves using the Pen Tool to draw a precise outline around an object, saving it as a path, and then converting that path into a clipping path for masking or exporting. Here's a detailed breakdown of the process:
Steps to Create a Selection Clipping Path
-
Open Your Image in Photoshop: Launch Adobe Photoshop and open the image you want to work with by going to
File > Open. -
Select the Pen Tool: Choose the Pen Tool from the toolbar on the left-hand side. You can press
Pon your keyboard to quickly select it. Make sure the Pen Tool is set to "Path" mode in the options bar at the top. -
Create a New Path: In the "Paths" panel (Window > Paths if it's not visible), click the "Create New Path" icon (it looks like a blank page). This ensures you're starting with a fresh path.
-
Trace the Outline:
- Carefully click and drag with the Pen Tool to create anchor points along the edge of the object you want to isolate.
- For straight lines, simply click to create anchor points.
- For curves, click and drag to create Bézier handles that control the shape of the curve. Adjust the handles until the curve matches the object's edge.
- Zoom in (
Ctrl/Cmd + +) for greater precision.
-
Close the Path: Once you've traced the entire object, click on the first anchor point you created to close the path, forming a complete loop.
-
Save the Path: In the Paths panel, double-click on the path you just created (usually named "Path 1") and give it a descriptive name (e.g., "Object_Clipping_Path"). This is crucial for later identification.
-
Convert the Path to a Clipping Path:
- Go to the Paths panel menu (the small icon with horizontal lines in the upper-right corner of the Paths panel).
- Select "Clipping Path..." from the menu.
- In the Clipping Path dialog box, select the path you named in the previous step from the "Path" dropdown menu.
- Set the "Flatness" value. This controls the complexity of the clipping path when exporting the image. A higher value (e.g., 8-10) can result in a simpler path, which is suitable for many images. A lower value (e.g., 1-3) preserves more detail but can create a more complex file. A value of '0' will create the most accurate clipping path. Experiment to find the best balance between accuracy and file size. Generally, the default value is sufficient.
- Click "OK".
-
Save Your Image: Save your image in a format that supports clipping paths, such as:
- TIFF (.tif): A lossless format that preserves image quality and clipping path information.
- Photoshop EPS (.eps): Suitable for vector graphics and print, and supports clipping paths.
Alternative Methods and Considerations
-
Using the Selection Tools: While the Pen Tool is the most precise, you can create a selection using tools like the Lasso Tool, Magic Wand Tool, or Quick Selection Tool, and then convert that selection into a path (
Window > Paths > Make Work Path from Selection). However, this approach is generally less accurate for complex shapes than directly using the Pen Tool. -
Layer Masks: Clipping paths are related to, but distinct from, layer masks. While layer masks can achieve similar visual effects, clipping paths are often used for exporting images for print or other applications where a vector-based mask is required.
Example
Imagine you have a picture of a product (a bottle) on a white background and you want to isolate the bottle for use in a catalog. You would use the Pen Tool to carefully trace around the bottle, save the path as "Bottle_Clipping_Path", and then convert that path into a clipping path before saving the image as a TIFF file. When you place that TIFF file into a layout program (like InDesign), the white background will be transparent, leaving only the bottle.
