Our friend Hermitian has made some fascinating claims about the Muscatine PDF, such as that it was created by Applewhite (because that’s what the author tag states) or that it was created before the AP released its own PDF. A careful analysis rejects such scenarios and provides us with a more logical and supportable workflow. Let’s first share what we know: Scott Applewhite was present at the briefing and the President’s statements on April 27, 2011 as supported by the set of photographs he took that day. One of the assets, marked DCSA103 or ID 110427018673, was sent to the AP office where it was imported into a PDF and made available to the public. The same assets were also provide to subscribers to the AP photo streams. The Muscatine Editor picked up the JPEG and imported it into Photoshow, cropped the image, resampled it, and removed the bluish hue and saved it as an PDF forgetting to clear the ‘Preserve Photoshop Editing capabilities and Embed Page Thumbnails. All the times line up quite nicely: Note that the times are in daylight time: So -4:00 = EDT and -5:00 = CDT
- 8:53EDT – Applewhite creates the image (1)
- 9:28EDT – The AP PDF is created (2)
- 10:00EDT – Muscatine editor imports JPEG into Photoshop and creates a PDF (3)
(1) IPTC tag
Time Created : 08:53:21+00:00
(2) PDF metadata
Modify Date : 2011:04:27 09:29:01-04:00 Create Date : 2011:04:27 09:28:48-04:00
(3) PDF Metadata
Create Date : 2011:04:27 09:00:38-05:00 (10:00:38 EDT) Metadata Date : 2011:04:27 09:01:39-05:00
So what happened? The Muscatine Journal obtained the AP JPEG and imported it into a Photoshop CS2 application. They cropped it, adjusted the color balance to correct for the bluish hue, and resampled it. The embedded tags clearly reveal the original source (DCSA103), as does the time tag…
Importing the AP JPEG into Photoshop and saving it as a PDF shows Applewhite as the Author, which is what confused Hermitian into arguing that Applewhite had somehow created the document.
When saving the PDF, the Muscatine editor forgot to turn off the option to remove the editing capabilities of Photoshop, which explains why the PDF is so large. When opening the PDF in Photoshop, you recover the 200x200ppi document, which was downsampled to 120×120 PPI in the PDF. And all lines up quite nicely. What apparently confused Hermitian is the author tag in the Muscatine PDF.
Of course, a quick experiment would have resolved this. So we have a consistent and logical workflow that contradicts Hermitian’s claims. So what is a scientist to do but to conclude the hypothesis to be falsified?

Update: There are three images in the Muscatine PDF, a thumbnail, a 120 ppi DCTDecode encoded JPEG and a 200 ppi image (1739×2071)
