Steamy piece of photography? (3)
I believe the answer is:
hot
'steamy' is the definition.
(thesaurus)
'of photography?' is the wordplay.
'of' indicates a hidden word.
'HOT' is hidden within 'photography'.
'piece' is the link.
(Other definitions for hot that I've seen before include "Flaming - spicy" , "Sultry in psychotic way" , "Sultry or angry" , "Very popular" , "Stolen - sought after" .)
