Sees red and steamy photo (8)

Ross

I believe the answer is:

snapshot

I'm a little stuck... Click here to teach me more about this clue!

'photo' is the definition.
(I know that snapshot is a type of photo)

'sees red and steamy' is the wordplay.
'sees red' becomes 'snaps' (I can't explain this - if you can you should believe this answer much more).
'and' means one lot of letters go next to another.
'steamy' becomes 'hot' (both can mean erotic).
'snaps'+'hot'='SNAPSHOT'

Can you help me to learn more?

(Other definitions for snapshot that I've seen before include "Bit of camerawork" , "pic" , "still taken quickly" , "Informal photograph" , "Informal photo" .)

I've seen this clue in The Telegraph.
