Openness of projectable photo? (12)

Ross

I believe the answer is:

transparency

This clue is a double definition.

'openness' is the first definition.
(I've seen this before)

'projectable photo?' is the second definition.
(a transparency is a photo viewed with a projector)

'of' is the link.

(Other definitions for transparency that I've seen before include "openness" , "Film slide" , "Photographic slide" .)

I've seen this clue in The Times.
