Ruddy family photograph (9)
I believe the answer is:
bloodshot
'ruddy' is the definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
'family photograph' is the wordplay.
'family' becomes 'blood' (blood can mean one's family).
'photograph' becomes 'shot' (shot is a kind of photograph).
'blood'+'shot'='BLOODSHOT'
Can you help me to learn more?
(Other definitions for bloodshot that I've seen before include "Reddened, inflamed eye" , "effects of booze?" , "(Of eye) streaked with red" , "(Of eyes) inflamed" , "Of eyes, red from dilated veins" .)
