Reflecting on an Image
"It's all done with mirrors" is a popular saying among professional magicians. These days, digital photography artists are using mirrors, of sorts, to create magical effects on their computer monitors. In a mirror image, one side of a frame is perfectly mirrored (reflected) on the opposite side of the frame—side to side or top to bottom. Here's how to do it.
Start with a visually strong picture. Actually, you have to start with a vision—an idea of how a subject will look when mirrored, or reflected, against itself. For this lesson, I'll use a picture I took in the desert of Rajasthan, India (Figure 3.101).
My first step was to select the entire image. I chose Select > All (press Command-A: Mac or Ctrl-A: Win) and then Edit > Copy (press Command-C: Mac or Ctrl-C: Win). That placed the image in my computer's memory.
Next, I chose File > New (press Command-N: Mac or Ctrl-N: Win) and clicked OK. A new, empty file exactly the same size as the original image was created. (Your image may look larger or smaller due to the percentage at which you're viewing your original picture. The viewing percentage is shown at the bottom left of the document window.) I chose Edit > Paste (press Command-V: Mac or Ctrl-V: Win) to paste my original picture into the new document (Figure 3.102).
While working with the newly created document, I went to Image > Rotate Canvas > Flip Vertically to create the reflection portion of what would be my final image (Figure 3.103).
I went back to my original image and chose Image > Canvas Size to open the Canvas Size dialog box. To create the reflection, I doubled the height of the Canvas; to make things easy, I rounded up the height from 4.288 inches to 9 inches (Figures 3.104 and 3.105). Here you can see that the Canvas size is a little more than doubled in height (Figure 3.106).
I made sure I was viewing both images at the same magnification percentage. I clicked the upside-down image and dragged it into the newly created white space in the original image until the images were aligned (Figure 3.107). Next, I used the Crop tool (press C: Mac or Win) to crop out the white space at the bottom of the image (Figure 3.108). The upside-down image was on its own layer (Figure 3.109). That made the next step easy. With the top layer (the upside-down image) activated (shown in blue here and activated by clicking it), I went to Filter > Distort > Ocean Ripple (Figure 3.110) and played around with the Ripple Size and Ripple Magnitude sliders until I was pleased with the result.
Here's the final image—a perfect reflection (Figure 3.111).
Of course, you need to work with an original picture that will make a nice reflection image. On the next page are two more examples that use the reflection technique—one a tightly cropped vertical shot and one created horizontally (Figures 3.112 and 3.113).
