Familiar name for a photo finish (4)

Ross

I believe the answer is:

matt

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

'finish' is the definition.
(I have seen 'Dull finish' mean 'matt' so perhaps 'finish' could also mean 'matt')

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for matt that I've seen before include "book" , "Without a shine, dull" , "Dull, lustreless" , "- Lucas (Little Britain)" , "Lacking a shine" .)
