I ran across this while watching some youtube videos on cinematography just for fun:
They use a still camera to storyboard which is pretty common now but I suppose you could just as well photograph your hand drawn storyboards if you wanted so you could email all that to you crew. I don't know what the screen writing program looks like. I venture to speculate it's probably fairly standard though. If you have no budget, or no money or just just don't want to pay for anything you don't HAVE to pay for, IE if you're a producer, it could be a bit of good luck to have access to proper screenwriting and story boarding software!
