Starts to photograph old lovers kissing at dance (5)
I believe the answer is:
polka
'dance' is the definition.
(polka is a kind of dance)
'starts to photograph old lovers kissing at' is the wordplay.
'starts to' indicates taking the first letters.
The first letters of 'photograph old lovers kissing at' is 'POLKA'.
(Other definitions for polka that I've seen before include "Lively dance, originally from Bohemia" , "Dot may be associated with this" , "Folk dance" , "Czech dance" , "Lively dance of Bohemian origin" .)
