...[Regarding the above articles,] evidence is available which shows that the cover photo on the HELP! album (both the US and UK versions) was *not* intended to spell HELP, nor any other message, in semaphore. Furthermore, simple research shows that the cover photo as a whole is *not* a mirror-image of the original photo, although some of the Beatles' individual images are reversed.
The photographer who conceived of and executed the photo, Robert Freeman, confirms that no semaphore message was intended. Freeman writes:
...I had the idea of semaphore spelling out the letters HELP. But when we came to do the shot the arrangement of the arms with those letters didn't look good. So we decided to improvise and ended up with the best graphic positioning of the arms. (Freeman, Robert _The Beatles_, Barnes & Noble, NY, p. 62)
This improvisation of arm positions probably explains the Beatles' "bad form", as described in an article above. The intention behind the arm positions was good "graphic positioning", not good semaphore. Thus, some liberties probably were taken in arm positions, and adherence to "good form" semaphore was a secondary priority (or possibly not of any concern whatsoever).
