Remember the game where you had to spot the difference in two images? Take a look at the two images below. Can you spot the difference?
If you noticed a change in the number of windows on the 3rd floor to the left of the porch area, you are right! The critical factor in making such an edit to the image is…Keeping Perspective. That can sometimes become very difficult…unless we are familiar with the Vanishing Point Filter.
This filter allows us to define the plane in which to perform our edits. Once the plane is defined, we can make changes to the image and the filter will apply the changes while maintaining perspective. In this example, by using the vanishing filter, the lines of the siding retain perspective. If we simply did a copy and paste, we could possibly make it work by transforming the pasted element, but that could be very difficult to do. Why not let the Vanishing Point Filter do that kind of work for us? Let’s take a closer look at this filter by walking through the steps to remove the 3rd story window…while retaining perspective.
First, open the image you want to make a change to. We will start with the image below.
To demonstrate using the Vanishing Point filter, we will remove the 3rd floor window as shown in the image on the right at the beginning of this article.
After opening the image in Photoshop, select Vanishing Point filter under the filter menu.
This will open the image inside the Vanishing Point window.
The tools are available down the left side. Our first step is to define the plane. To do so, verify the Create Plane tool is the active tool.
To define the plane, select a plane in the image, and click on the four corner points of the plane. In this example, we will define the plane on the upper left side of the porch area.
A blue bounding box will appear as you define the four corners of the plane. When completed, the bounding box will appear as below:
Now we are aready to edit the image. Our goal is to remove the left window from the 3rd floor. To do this, we will replace the left window with the white siding.
After defining the plan, we’ll select the area we want to replace the window with. (ie. the siding) Select the marquee tool, and click and drag in the image area to select the siding to the left of the window.
Copy this selection (ctrl-c), paste it (ctrl-v), then place the pasted area over the window using the move tool. To move the pasted area (it is pasted right over the selected area), place the cursor inside the selected area (the cursor turns into the move tool), and click and drag the area over the window.
If the area needs to be tweaked a bit to fit over the window, select the transform tool, and pull out/in on any of the handles around the selected area.
Click OK in the top right of the Vanishing Point filter window to accept the changes and close the window.
Here is the edited image:
We only ‘removed’ a window in this sample exercise. You could also add windows, or a door, or…? Next time you need to keep perspective when editing an image, don’t forget the Vanishing Point filter.
