This is the 2nd of two shots, this example from the book showing stronger sharpening.
The previous one (see 'previous' at top or bottom right) is of a softer sharpening
at a setting of only '25' rather than '150'...

This was in connection with the review and my comment about the current Kindle Edition image screenshots, at the
book's Customer Reviews pages.

The screenshot was a png file and I saved it via Irfanview as a jpg, at 95%.
