ant man shrinking effect

orangepeel Posts: 87 Just Starting Out

just wanted to ask how I would be able to pull off the ant man bathroom shrinking effect, with the camera move and such. Should I take a plate of the camera moving down into the bath tub, and then greenscreen my actor and track it to something in the scene in one whole sequence? or should I try and replicate the white flash that happens when antman presses those buttons on his thumbs, and maybe cut a tripod shot where actor is trying to press buttons with the greenscreen footage (with the moving camera plate) when he shrinks. Any ideas would be appreciated!
