Painter mentally capturing burial (9)

I believe the answer is:

interment

'burial' is the definition.
(I know that burial can be written as interment)

'painter mentally capturing' is the wordplay.
'capturing' indicates the answer is hidden within the clue (some letters captured or held by the clue).
'INTERMENT' can be found hidden inside 'painter mentally'.

(Other definitions for interment that I've seen before include "planting" , "Procedure governing body" , "Burial" .)

I've seen this clue in The Telegraph.
