Can the view point or angle an object is taken at be changed? The answer is: yes. Anytime Photoshop changes the view point of an object, it warps the perspective and completely changes the view of an object. However, why change it?
Sometimes the camera captures the angle of objects inaccurately. This causes lines and flat surfaces to look distorted in comparison to what they actually look like with the naked eye. When distortion occurs, “Perspective Warp” comes into play and fixes the issue. The tool is best used to straighten lines and rotate two dimensional and three dimensional shapes. This tutorial demonstrates how to do so by using Photoshop CS6 and newer versions. This can take anywhere from A computer device should have at least 512 megabytes of video “RAM” for perspective warp to work on 16-bit and 32-bit documents. If this feature is available but cannot be clicked on, it will be mandatory to enable the graphics processor. The graphics processor enables the video card to power or accelerate this feature.
Adjust Perspective by Rotating an Object
1. To get started, duplicate the layer by pressing “Ctrl+J”. Right click on the copied layer and select “Create Smart Object”. This will apply the perspective warp nondestructively.
2. Click on “Edit” > “Preference” >”Performance” on the main menu activate the video card by choosing the “Use Graphics Processor” check box.
3. Click on the document to make gridlines appear. The purpose of these gridlines is to layout the foundation of a new angle. This explains why the tool defaults to “Layout” mode. Move those gridlines along the border of the object by dragging the corners or with the arrows on the keyboard.
4. Make certain the lines are parallel to the lines on the object. More than one grid can be applied to the object and snapped together to make three dimensions. Increase the quantity of grids as needed.
5. In the options bar, change modes from “Layout” to “Warp”. This mode will manipulate the structure of the object.
6. Press the “Shift” key and then hover over each vertical line so that horizontal and vertical lines move together. Each line will turn yellow to indicate a link. Failure to hold vertical and horizontal planes together will cause the object to increase in distortion.
7. Now drag the circled control points to influence the angle of the object and fix the perspective of the image. Pay attention to the angles and proportions so the object warps into a realistic position. When finished, press the “Enter” key.
There is a possibility that the edges of the image may be compromised after this process, causing blank or checkered corners to appear. If this happens, use the basic elements of the “Crop” tool to trim down the image. To open the “Crop” press the C key, pick an appropriate ratio, then pull the image around to straighten if needed. Hit the “Enter” key when done. If that does not completely resolve the issue, use the spot healing tool to fill the missing areas. To use the spot healing brush, create a black layer first. After that, click the band aid icon, select “Sample Layers”, pick a brush size and drag along the blank areas. This should replace the checkered spots with a texture that fits.
