The central or innermost part, the ‘heart’ of anything.
‘the little plot of ground in the very core of a capital’
This word means the essence of what you need to be in front of the camera – the seed. The source, the beginning, the base from which you let us see you. We can also call it our centre. This ‘core’ has to be developed first before one adds accents, character work, motion capture technique etc.
