Trade show for users showing off numerous revelations (9)

Ross

I believe the answer is:

exposures

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

'revelations' is the definition.
(exposure is a kind of revelation)

'trade show for users showing off numerous' is the wordplay.
I cannot really understand how this works, but
'show' could be 'expo' (I've seen this before) and 'expo' is found within the answer.
an anagram of 'users' is 'sures' which is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for exposures that I've seen before include "Revelations (of scandals, etc)" , "Snaps" .)
