You can do this too, and satisfy yourself that the work we do here is honest and credible. Any scientific experiment, to be valid, must be repeatable. I post not only the comparison results, but the photos used in the comparison. All you need do is download those photographs, and load them individually into Microsoft Paint.
In Paint, you can only work with one photo at a time. One you have one up, Paint has a “Resize” button to adjust the photo until the pupils of the eyes are at the correct distance. You are asked to enter a horizontal percentage adjustment. I use one inch as the standard pupil distance, and to get to that increase or decrease the photo size in increments until I am satisfied I am at exactly one inch distance between pupils. In this photo of Chris Farley, the eyes are big, so it is easy to adjust center-pupils to one inch each by trial and error, maybe adding 10 percent, subtracting one percent, etc. etc., until the distance is exactly one inch on your screen.
Then do the same for your comparison photo, in this case, Michael Moore. You have to save the Farley photo and upload the Moore photo and then perform the same procedure.
Once certain that the eyes are both exactly the same distance apart, a comparison can be run. Paint allows you to copy all or part of a photo. Click the “Select” key to be sure you are in the right mode, and while holding down the left mouse key drag it until you have enough of the face for a comparison. Then release the mouse key, right click, and choose “Copy.”
You can now recall the original photo, in this case Farley. Once you have it on your screen, right click and “Paste.” The half-face you just copied will appear. You can drag it with the mouse to line it up, and make fine adjustments with the arrow keys. You must be sure, to be true to the procedure, that the pupils are one inch apart, now the distance between Farley and Moore’s pupils.
All that done, it is apparent from this composite that we have a negative result. Farley and Moore are two different people. The lips, nose and ears do not line up. This is generally the result. Only occasionally do we manage to uncover a zombie, as happened with Maury Povich below. Many times the results are intriguingly close, but I do not fudge them. It is either a hit or a miss, in this case, a miss. Work is complete.
Note: I use PhotoShop to lighten and level the eyes in photographs, which is why you see dotted frames around Farley and Moore. I realize most people do not have that program, but Paint is usually enough to do the job. You merely need to select photos of people in the same pose for comparison. Free and copyrighted images abound on the Internet, but Getty Images, guaranteed free, is always a safe bet. Also, the Microsoft Snipping Tool is an invaluable aid.
