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.

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 {
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 {

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 {

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 {
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 {
