Following is the text of the article.
This one is courtesy of MissTickly from the Obama’s Garden blog and her article, The Audacity of Seal. I don’t know why birthers have to ramble on and on to make a simple point, but let me save you having to click the page down button 28 times and tell you what her article says (my words):
The caption (“State of Hawaii – Department of Health”) on a birth certificate’s embossed seal, when viewed from the raised (embossed) side, should read normally, but on Obama’s it is a mirror image.
OK, did everybody understand that? The rest of the Obama’s Garden article, and particularly stories of threats against their children, doesn’t add much to my one-sentence explanation except to spin an atmosphere of intrigue and to suggest that she’s come upon a bombshell error in the COLB that threatens the Obama administration to its foundations.
he argument hinges on one essential detail: which side of Obama’s Certification of Live Birth is raised. Obama’s Garden helps us figure that out with the following convenient illustration:
That picture makes it crystal clear which is which — or does it? Here is the same image, rotated 180 degrees (turned upside down).
What happened? The raised and lowered portions seem to have been switched, but all I did was show the same picture from a different direction.
The shading information in images that depict surfaces of 3D objects cannot be perceived correctly unless the direction of the illuminating light source is known, and, in the absence of this knowledge, adults interpret such images by assuming that light comes from above.
Let me give you two more examples of FactCheck image number 7, this time viewed from the side:
Even though these are the same photo (just turned), one clearly appears raised and one clearly appears lowered. This last image appears “correctly” to the eye with the seal raised and the text right.
Yes, this controversy
is nothing more than an optical illusion. Obama’s raised seal is raised on the back side of the document (exactly as it is on other certificates) and reads correctly in concert with the registrar’s seal and the date stamp. In all fairness to Miss Tickly, this is a very compelling optical illusion, but an illusion nonetheless.
While the preceding proves the
presence of an optical illusion, I can anticipate an objection from someone who supports Miss Tickly, and that is to point to FactCheck photo # 1.
I can rotate this image any way I want and it still appears embossed. I am still studying this illusion. One thing that may contribute to it is the “open window” that appears in the background which might lead the eye to think that it is the cause of the glare on the paper, but I think it more likely the glare is caused by an overhead ceiling light. I don’t like loose ends.
Here is the seal on the De Costa certificate printed in 2002 first shown normally, and then upside down.
Here’s a photo I found on the Internet that shows how powerful the illusion can be:
