In my work I am dealing with *.CR2 raw images taken by a Canon DSLR in raw mode.
When I read about the format here, I was surprised to find that it has 4 TIFF IFDs which contain a) Original Size JPEG Image b) Thumbnail JPEG image c) Uncompressed RGB data d) Lossless JPEG image.

My impression until now was any camera captured RAW image file would have Raw Bayer Data i.e. R,Gr,B,Gb kind of bayer data, and some EXIF data about camera capture settings etc.

But after reading this CR2 specification I am slightly confused as to how can it have a RGB data or even surprisingly JPEG data. This seems to be the data after demosaicing(obtaining the missing R/G/B pixel data for the original sensor Bayer pattern). If thats the case I would not consider *.CR2 as "truly raw" data. It has done demosaicing before dumping the socalled raw file.

Am I missing something?

Does any other Camera Raw formats(e.g. Nikon - *.NEF, Kodac - *.kdc, Pentax - *.ptx/pef,...) have real raw bayer data without any processing done?


Question: Privacy of Gmail for business?
Answer: If you're not encrypting your email, then you really can't be said to have any expectation of email privacy, so the flap about whether or not they scan your emails makes little sense to me. That email is scanned at every step of its journey, by various virus and spam scanners.

Google claims various rights regarding your content in their TOS, but the inherent copyrights, etc. stay with you. I've worked with Fortune 500 companies whose email was put through Google specifically because they could be relied on to keep it (it vastly simplifies SOX compliance, for example).

But if you're really worried about privacy, email is not the best medium.
