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.

Update:

(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…

The Muscatine Journal, embedded thumbnail

Update: Thumbnail image added

thumb

Our friend Hermitian is still struggling with the work flow relating to the Muscatine Journal PDF. While the ‘author’, ‘title’ and subject tag may have caused some confusion as to the true author, I have shown how a simple importing of the jpeg provided by AP creates J Scott Applewhite as the author.

Now Hermitian is excited that he has found an embedded thumbnail in the file. Again, as I will show, the simple workflow explains all this. See the ’embed page thumbnail’ part 🙂

CS6 PS SettingsHermitian: To the contrary, for NBC’s claim to be true, the Muscatine technician would have had to strip all the METADATA from “ap_obama_certificate_dm_110427.pdf” and then with Photoshop CS2 create entirely new METADATA for “4db82608b486f.pdf”. Thus he would have to type in the lines which credit the AP, Scott Applewhite, the AP caption writer and all the references to Washington DC and NOT enter a single line which identifies the Muscatine Journal, himself and the city and state of Muscatine Iowa. And the lines that credit the AP, Applewhite, the caption writer, and Washington DC all begin with the label /</photoshop: embedded within the METADATA.

I just did the experiment Hermitian. You should have done so as well 🙂 Diligence…

Hermitian is still unfamiliar with the metadata of the AP JPEG. He foolishly extract the metadata from the PDF but forgets that the embedded JPEG contains a lot of metadata…

For example

AP MetadataOh and the metadata… Really Hermitian…

Experiment – Muscatine PDF and Author

I opened the AP jpeg in Photoshop (CS5) and saved as PDF… The results are interesting as Hermitian had made so much about J Scott Applewhite being the ‘author’, but the same happens when you open the jpeg ad save as PDF. It even mentions the Image Conversion Plugin and the Subject – This handout image provided by the White House shows a copy of the long form of President Barack Obama’s birth certificate from Hawaii \(AP Photo/J. Scott Applewhite\) and title Obama. So that little mystery has been resolved. What remains are the time stamps and the

Without access to CS2 Photoshop, retracing the exact steps and studying the metadata will be complicated. But as I had already expected the Author information has been resolved.

Muscatine PDF with embedded ‘PSD’

Hermitian: Now maybe you Obots could explain how the PDF that produces the final images does not contain the final images but yet the final images just pop out when the file is opened in a bunch of different PDF editing programs? And please also explain why that same-sized final image sometimes pops out at 120 PPI x 120 PPI and some times it pops out at 200 PPI x 200 PPI whereas the two images that are detectable within the PDF are both 72 PPI x 72 PPI resolution?

Hermitian: W = 24.153 in. ; H = 28.764 in. (or W = 1739 P ; H = 2071 P). The smaller image is a certificate image with near-White background. The page size is W = 14.486 in.; H = 17.264 in. (or W = 1739 P ; H = 1243 P).

First of all, Hermitian has made a slight error here. the W of the second image is 1043 not 1739.
