AP JPEG and the Muscatine PDF – Resolved

The ‘pièce de résistance‘… Color adjusted inside Photoshop… While our poor friend was way off in his speculations about the AP JPEG, I was actually working diligently, one my sidekick Kevin had sent me the jpeg, to repeat the experiment that Hermitian should have done before making poorly supported accusations. Compare this with the Muscatine version (on the right). Not bad for a quick adjustment…

Muscatine PDF and the AP JPEG – Part 2

Remember Hermitian’s hypothesis that somehow, not only was the Muscatine PDF created before ABC news created its PDF (Hermitian had without evidence concluded that Applewhite was somehow the author), but was also created by Applewhite. As I have shown now, a simple workflow again explains the data much better.

Ok, I did the following

  1. Import the JPEG into Adobe Photoshop
  2. Change image resolution to 200ppi
  3. Crop image (rough crop)
  4. Save as PDF – downsample JPEG to 120ppi, high quality, preserve editing and fast load, PDF 1.3 compatible, embedded thumbnail
  5. Extract JPEG

The resulting pdf was 5.8 MB (5,812,654 bytes) and 8.7 × 10.28 inches versus 5.9 MB (5,892,754 bytes) and 8.7 × 10.36 inches for the Muscatine PDF. Not bad since I do not have CS2 photoshop…

Both jpegs are now YCbCr4:2:0 encoded…

Things get more interesting. Matching Quantization tables for the extracted JPEG. I’d say another Hermitian Myth laid to rest. The best 20 minutes of my time so far 🙂

Tracking the AP JPEG – Introduction

My trusted side kick and fellow contributor, Kevin Vicklund has shared with me his DCSA103 JPEG. The image is 300 ppi versus 200 ppi for the ABC PDF document and 120 ppi for the Muscatine Journal PDF. Hermitian had claimed that Applewhite was the ‘author’ of these PDF’s because his name showed up as the ‘author’ but as I will show, this happens automatically as part of a simple workflow. While our friend is still struggling, I have, in the spirit of scientific inquiry, looked at the actual data.

AP110427018673.jpg was obtained by our friend Kevin from APImages and holds various surprises: First of all the JPEG is not subsampled and secondly, the resolution is 300ppi. As shown elsewhere, the image was created at 8:53AM on April 27, 2011, soon after the press conference had started.

The Muscatine experiment – aka shooting fish in a barrel

Let’s compare the metadata in the Muscatine PDF with the metadata of the AP JPEG imported into Photoshop and saved as a PDF? There is are two one missing entryies: Urgency and DateCreated, I will be repeating the experiment. Ah, somehow I missed DateCreated… It is clear however that the metadata is extremely similar… Anyone having access to CS2? I assumed that Hermitian had done this experiment, after I explained it some time ago.

There are two differences: the time is embedded in addition to the date and there is no urgency tag.

Kevin Vicklund to the rescue

Yes. Urgency: 5

The METADATA from the Muscatine Journal is identical to the METADATA produced by importing the AP JPEG into Photoshop CS2 and saving as a PDF, allowing for current date and time.


(photoshop:Urgency) has been deprecated in 2005. (Need to confirmed)

DateCreated: Use this field to record the date (and optionally, the time) the photograph was created, not the date when youscanned or edited the image.

Another myth bites the dust, I love it.. You’re the best Hermitian, you inspire people to push their research…

Hermitian and Applewhite’s JPEG

Hermitian: Talk about missing the workflow !  The Applewhite original was not a JPEG but rather a PDF.  Remember the totally missing camera METADATA in the Applewhite PDF ?  No !!!  I didn’t think that you would remember.  I don’t recall that you ever posted any camera METADATA from a JPEG that Applewhite created with his camera.

Actual, his original was a jpg which was turned into a PDF. The jpg can be extracted from the PDF, which I did, and I showed you the relevant metadata. Have you been asleep? As to me never posting the metadata, again you are wrong…
