From that site: "The raw output from the digital scan of a 70mm Hasselblad frame, is a huge 1.3GB, 16-bit TIFF file. At approximately 11,000 pixels square, a single image would require a 12-foot x 12-foot computer monitor to display the whole image at standard resolution. "

The Flikr images must be jpg conversions of the original TIFFs, certainly in an attempt to reduce file sizes. I'm not sure where the 11,000 comes from. The JPGs are 4400x4600. Perhaps the original TIFFs were 11,000x11,000 pix.

11,000 pixels / 72DPI = 152 inches = 12' 6". Math checks out.

Yep! I wonder if it is possible to get the original TIFF files from NASA?

I've commented[1] above that the high-res scans were done by ASU, for example the cover of the book is this scan: http://tothemoon.ser.asu.edu/gallery/Apollo/9/Hasselblad%205...

And on that page there's a download button for several version, with the raw image (the link has a .TIF extension) being 1.3 GB big...
