After moment, cry echoes: one's involved in shooting (5,4)
I believe the answer is:
flash bulb
'one's involved in shooting' is the definition.
I can't tell whether this definition defines the answer.
'after moment cry echoes' is the wordplay.
'after moment' becomes 'flash' (I've seen this before. I am not sure about the 'after' bit.).
'cry' becomes 'blub' (I've seen this before).
'echoes' is a reversal indicator (I've seen 'echoing' mean this (echo can mean to reflect or bounce back)).
'blub' reversed gives 'bulb'.
'flash'+'bulb'='FLASH-BULB'
Can you help me to learn more?
(Other definitions for flash bulb that I've seen before include "Old camera attachment" , "Source of light for photo" , "Photographic light source" , "this will suddenly lighten you" , "Photographic accessory" .)
