Reader takes Histogram Idea even further
Reader Josh Millard wins the Reader of the Week Award. He took my idea of embedding an image in a histogram even further. While I was only able to hide a histogram-picture in a gradient, Josh has figured out how to take all those pixels from the gradient and create a photorealistic grayscale image.
His first proof-of-concept was, rather inexplicably, a grayscale photo of a drainpipe that hides the skyline of Miami in its histogram. Then he created a photo of Miami that hides the skyline of Miami. And finally he used my original example to hide the skyline of New York City in the original source image of the skyline of New York City. So this picture:
…has this histogram:
Josh is a genius. You can see the other examples of Josh’s work, as well as a link to his script that handles all the magic, at Josh’s blog.
