To add perspective points in the Vanishing Point filter in Photoshop, you essentially define a perspective plane by setting the four corner nodes that define the plane's grid.
Here's how:
-
Select the Create Plane Tool: Within the Vanishing Point filter dialog box, choose the "Create Plane Tool" (usually the first tool in the toolbar).
-
Define the Corner Nodes: Carefully click on the areas in your image where you want to establish the perspective plane's corners. Aim for visually distinct points that represent the edges or corners of a real-world plane within the image (e.g., the corner of a wall, the edge of a building). The order in which you click the points matters as it defines the orientation of the grid.
-
Adjust the Grid (if needed): After placing the four points, Photoshop automatically generates a grid based on your selections. You can fine-tune the perspective by:
- Dragging the corner nodes to adjust the size and shape of the grid.
- Dragging along the edges of the grid to extend or shrink it.
- Using the "Edit Plane Tool" to further refine the plane's parameters.
Key Considerations for Accuracy:
- Accurate Placement: Precise placement of the corner nodes is crucial for a realistic perspective. Zoom in to ensure accurate placement on key visual elements.
- Planar Surfaces: The Vanishing Point filter works best with flat, planar surfaces.
- Multiple Planes: You can create multiple perspective planes in the same image if you have multiple surfaces with different vanishing points.
By carefully defining these corner nodes, you effectively add perspective points which Photoshop uses to build the perspective grid in the Vanishing Point filter.
