ok so i know basically use a tripod have the characters act out the parts then mask and what not, thing is id like to have the camera handheld and also is there any way around masking? i was thinking green screen but would the lighting look off? the scenes that ill need multiple of the same person will be outside probably sunny as well. i wil need to clone multiple zombies, when i say multiple i mean at least 8, any ideas? and yes they will probably over lap eachother in some shots.
