The basic idea behind the CTRL+A pictures is that both images are always present and visible in the original image. Using our checkerboard analogy, all of the black squares would contain pixels from the main image, and all of the red squares would contain pixels from the "hidden" image. However, the "hidden" image is barely able to be seen, if at all. So why is that? The reason is the choice of color levels. The image is subdued by altering its color levels to make it blend in with the main image. When highlighted, all the pixels from the main image are covered up, leaving only the pixels from the "hidden" image to be seen.
