Metameor?

 

"Metameor" was written on the slide, as best as I can judge...but that turns up zilch on Google.

The image - might shows the Ksar Ouled Soltane, a fortified granary located in southern Tunisia. 

Historical Purpose: Built by the Amazigh people in the 15th century, these structures served as fortified storage spaces called ghorfas for grain and dates. 

Pop Culture: It gained international fame as a filming location for the slave quarters of Mos Espa in Star Wars: The Phantom Menace. 

The slide's odd colour cast - unknown. Possible a slight light-leak.

The woman - You've guessed it, unknown. But she seems to be carrying a Swann Hellenic (WF & RK SWAN LTD LONDON) travel bag.

Bonus Fact - Ksar Ouled Soltane is located in the town of Soltane, which is south of Tataouine. Hmm, sounds familiar. 

Bonus -
