I am visualising a concept for a short film, but I would like to have an underwater scene where I can actually see at least half the body of a person in the water, shooting from below.
I have learnt that the fish tank methods are good enough for close ups. If I need half the body to be shot underwater, I will need a very huge tank to contain the actor.
I am wondering if there could be more ways to do this provided that I could not really go underwater in the ocean or a pool.
Thank you for incoming suggestions.
