I worked on the television series CSI: Las Vegas as a prop maker working with an amazing team of artists and crafts people where I helped to make, build, and fabricate many, many hundreds of miniature props and pieces. Everything had to be made in duplicate because the actors had to handle the actual miniature props which were built at 1/4″ = 1′-0″ scale, but there also had to be a duplicate model of the one the actors handled which was for actual filming so a camera could travel through the miniature set. Those larger models were built at 1″ = 1′-0″. A much larger model, to say the least.
