This is a picture of a woman called Zoe which was taken on the Island of Capri probably in the late 1950s. As far as I can see, she seems to be opening her Lightmeter case, which is attached via a strap to her camera, so I assume she is about to take a picture of the view in front of her.
The only information on this medium format 6x4.5 colour slide are the two words 'Zoe' and 'Capri' so I can't give an accurate location or date, but to my eyes the dress and shape of the subject's glasses certainly suggests the 1950s.
