One of those not in the picture is accused of this? Not wanting to be shot!

I believe the answer is:

camera-shy

I'm a little stuck... Click here to teach me more about this clue!

'not wanting to be shot' is the definition.

I don't understand how the rest of the clue works.

(Other definitions for camera-shy that I've seen before include "Unwilling to be photographed" , "Chaser may be apprehensive of having photo taken - bashful?" , "Reluctant to be photographed" , "Afraid of the lens" .)

I've seen this clue in the Irish Times.
