Low budget movie needs more preproduction as we are trying to lock in all the details before we go in to shoot

If you are using a wide-angle lens or a long lens , if you fill in the frame they both have the same depth of field

Note :

if using video : Green is better color

Red screen is better for glass

Blue screen is great as it is spectrally high.
