File Manipulation Notes

For several reasons, the original scans do not print or even read particularly well so I created display files in JPG and PDF formats. The directory tree preserves the original scan files and intermediate files created during manipulation to create the "corrected" display formats. That should permit reprinting the pages if, for example, museum display copies degrade over time. That should also permit anyone else to review or redo the file manipulations if they choose. The notes below are intended to aid any such effort.

Scanning Limitations and Irregularities

The original scans at the National Archives were full color scans on my HP Scanjet 5470C scanner attached to a notebook computer.

The glass scan area on that scanner is 8 5/8 by 11 ¾ inches but the log pages are about 10 by 16 inches. The scanner width was just barely adequate to capture the handwritten log entries with blank margins omitted. In a few cases, I lost a single character at the margin but I’ve seen no such cases where I think there’s any ambiguity about the missing character.

The 11 ¾ height was inadequate to capture an entire page in a single scan, so I took two overlapping scans of each page.

The log pages were stapled together into monthly binders and archive rules prohibited separating them. That required spreading the bound pages onto the scan glass and resulted in many scans not being squarely aligned.

The color scan captured yellowing that exists on many of the original pages.

File Manipulations

All file manipulations were done on Windows 2000 Pro Service Pack 3.

All files have a common {filename} format of {YYYYMMDDP} where:

 

YYYY

Year

 
 

MM

Month

 
 

DD

Day

("00" on monthly cover pages)

Original Scans

The original scans to PDF were done with HP Precisionscan Pro 3.13, with Output Type "True Color" and the Save As PDF option.

The resulting images were saved in subdirectory Original Scans as {filename}.pdf.

Extraction

The original PDF scans were displayed in Adobe Reader 6.01 and individual page images extracted with Select Image and Copy. The clipboard was pasted into Microsoft Photo Editor 3.0 with Paste As New Image. The result was a true color, medium compression JPG at 96 pixels/inch with a variable size of about 9 by 12 inches.

The resulting new images were saved individually in subdirectory Working Files as {filename}a.jpg and {filename}b.jpg.

Alignment

If the images in {filename}a.jpg and {filename}b.jpg did not appear to line up well, then either or both were opened in Adobe Photoshop 6.01 and rotated with Rotate Canvas and the Arbitrary option. Rotations were always 1 degree or less, usually 0.25 to 0.50 degrees.

The resulting images were re-saved in place in subdirectory Working Files as {filename}a.jpg and {filename}b.jpg.

Combination

The intermediate files {filename}a.jpg and {filename}b.jpg were opened (or still open) in Microsoft Photo Editor 3.0 and each image re-extracted with Select All and Copy. The clipboard was pasted into a new image in Adobe Photoshop 6.01, created as transparent RGB at 96 pixels/inch with a size of 10 by 18 inches. The {filename}b.jpg image was pasted first and moved to the bottom of the canvas. The {filename}a.jpg image was pasted second and moved to overlay and align with the top of the {filename}b.jpg image. Excess canvas was removed Rectangular Marquee Tool and Image Crop.

Line Avoidance/Removal

During the combination, a visible line could usually be avoided by moving the bottom selection line for the {filename}a.jpg image (in Microsoft Photo Editor 3.0) up to a trivial white space area. If significant visible line remained, it was painted out in Adobe Photoshop 6.01 with the Paintbrush Tool using a color captured from immediately adjacent space using the Eyedropper Tool.

Yellowing Removal

As a last step before saving the result from Adobe Photoshop 6.01, a New Adjustment Layer, Hue/Saturation, was created and Yellows were adjusted to 100% Lightness to remove all yellowing without any effect on black or blue printing and handwriting in the image.

The resulting image was saved, with layers, in subdirectory Working Files as {filename}.psd.

The final image was saved in subdirectory Display JPG as {filename}.jpg at medium compression.

The three working files, {filename}a.jpg, {filename}b.jpg, and {filename}.psd were archived in subdirectory Working Files as {filename}.zip.

Alternative PDF format

The final image {filename}.jpg was opened (or still open) in Microsoft Photo Editor 3.0 and "printed" to a PDF using Adobe PDFWriter (PDF Driver 4.05).

The image was saved in subdirectory Display PDF as {filename}.pdf.

Alternative Thumbnail Format

The thumbnails were created from Display JPG using Web Picture Creator 1.30.

The images were saved in subdirectory Display Thumbs as thumb_{filename}.jpg

Footnote regarding deck log pages for POW dates 1967-10-22 and 1967-10-23:

The four log pages for 1967-10-22 and 1967-10-23 were scanned and the images manipulated somewhat differently than the other log pages. At the archives, Patti found those pages at the very last minute after I'd already packed up our equipment. Those pages were scanned on a copier at the archives and printed on paper at 80 percent reduction.

To get machine-readable images, I later re-scanned the paper copies to PDF. JPG's were extracted from those PDF's in a method similar to that described above [Adobe Reader 6.01 Select Image and Copy, then Microsoft Photo Editor 3.0 Paste As New Image ].

The resulting images were saved in subdirectory Working Files as {filename}.jpg

Those JPG's had a much higher pixel density that other log images and shadows from the original copier had left large, irregular black areas along one side or the other. They were opened in Adobe Photoshop 6.01 and the Image Size reduced to 33 percent (from about 2500 by 3500 pixels to about 850 by 1200). The images were rotated (by more than 2 degrees in one case). The irregular shadows were removed with the Eyedropper, Paint Bucket, and Paintbrush Tools and the result cropped with the Rectangular Marquee Tool and Image Crop

The final images were saved in subdirectory Display JPG as {filename}.jpg at medium compression.

The working files, {filename}.jpg, were archived in subdirectory Working Files as {filename}.zip.

Footnote regarding web content:

In order to create log page images and thumbnails that were smaller and more web-friendly, I created an alternate set of images from Display JPG using Web Picture Creator 1.30 at about a 50% image reduction.

The resulting images were saved in subdirectory Web Content as {filename}.jpg and thumb_{filename}.jpg
