Not wanting to be shot (6-3)
I believe the answer is:
camera-shy
'not wanting to be shot' is the definition.
(camera-shy means unwilling to be shot on film)
'be shot' is the wordplay.
'be' becomes 'camera' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'shot' becomes 'shy' (both can mean an act of throwing something).
'camera'+'shy'='CAMERA-SHY'
Can you help me to learn more?
(Other definitions for camera-shy that I've seen before include "Reluctant to be photographed" , "Chaser may be apprehensive of having photo taken - bashful?" , "Afraid of the lens" , "Unwilling to be photographed" .)
