The next stage was compositing the keyed blue screen footage into the scene. Again for this I was using After Effects.
I began with the background of the room interior, I duplicated the footage multiple time so that I could beak it down into separate elements, this would help me create a sense of depth. From there I was able to composite in the live action footage.
After I separated the mirror into different layer I applied a radial blur to the background layer.
Next was compositing the footage. I brought the footage in as a pre-comp and adjusted the positioning of the layer in z depth, and keyframed the position to track appropriately with the background footage.
After placing the initial layer, I then began colour correcting the footage.
I would adjust this later on as I still had to apply a Caustics layer to create the ripples, and would be able to adjust the colour tones of that layer.
