AP JPEG and the ABC News PDF – Resolved

Our friend Hermitian stepped in it again..

You sure are wasting a lot of time on a dead end NBC. Serves you right for switching your starting JPEG image. Maybe you already know this (and maybe you don’t).

So the bottom line is your workflow doesn’t work. So you have no choice but to back up and use the other larger AP11042717913.pdf image to create the AP NBC News PDF.

Starting with this larger JPEG image one only has to open the JPEG in Adobe Acrobat CC and then save the auto-converted PDF.

It’s really not complicated when you know how to use the high-level Adobe PDF Tools.

The problem is that our friend’s knowledge appears to be limited to high-level Adobe PDF tools, while we researchers have many tool available. Sure, they are open-source and widely distributed…

convert AP110427018673.jpg -density 200×200  -sampling-factor 4:2:2  -quality 77 AP110427018673den.jpg

The resulting file is 200×200 ppi, Image Size : 2698×3234 Y Cb Cr Sub Sampling : YCbCr4:2:2 (2 1) and the quantization tables match.

Another myth bites the dust. The AP JPEG can be tracked all the way to ABC News and Muscatine where the editors used different processes to create a PDF and distribute it. For some reason, our friend Hermitian had been confused into arguing that Applewhite was somehow the author of both documents and that the timeline did not make sense. We now know the rest of the story and it all lines up quite nicely, as expected.

  2. The METADATA from the “AP JPEG” file “Obama_Birth.jpg”.

    And once again, Hermie fails to properly download a file.

    However, it does look like Hermie is starting to discover that the metadata is not a reliable means of determining whether Applewhite created the instant file, that it can indeed be carried over from one file to another when the original is converted into another format or otherwise edited.

  3. Wait what? Hermie’s CreateData on the Obama_Birth.jpg is after the ModifyDate and MetadataDate! How on earth did he manage that fuckup? Did he change the date on his computer?
