I think three different computer forensic experts have deemed them photo shopped and forgeries!!!
All such claims are meaningless since the Hawaiian State Department of Health has verified that they have Obama's birth certificate on file.
The only remaining question about the birth certificate that is relevant to Obama taking office is whether the original vault copy shows the birth hospital and doctor's signature or whether it was an alternate type of birth certificate that was allowed between 1959 and 1972. Only if it is the latter type would there still be a legitimate question about where Obama was born.
As to the authenticity of the modern certified copy of the BC displayed by the Obama campaign.
1. There is no question that he could legitimately produce such a document.
2. The "experts" critiquing it are are self-described experts.
3. All of the complaints about the appearance of the document can be explained as the result of the scanning process.
4. The photographs of the same document from various angles by factcheck.org show it to be a real document with the state seal. (The conspiracy theories about factcheck with regard to this are tinfoil stuff.)
