Eminent person came face to face with the monarch — photographer's got it? (5,5)

I believe the answer is:

light meter

'photographer's got it?' is the definition.
(device used by a photographer)

'eminent person came face to face with the monarch' is the wordplay.
'eminent person' becomes 'light' (as in the 'leading lights' of a field).
'came face to face with' becomes 'met'.
'the monarch' becomes 'er' (abbreviation for Elizabeth Regina, British Queen).
'light'+'met'+'er'='LIGHT METER'

I've seen this clue in The Guardian.
