Working with combinations gives you a variety of looks. The film industry responds quickly to advances in technology. Companies such as Kodak are constantly improving and introducing new products that allow me to be more creative in any of the conditions in which I shoot. In the past I didn't like to force process because of the increased grain. Then the grain structure became so good, forcing didn't bother me.
Lenses are also of a quality that never existed before.
The Cookes and Primos are famous for their color consistency throughout the range of lenses. The color timing is consistent. The result is a better look and a more realistic rendition. Advances in digital technology allow me to construct images that wouldn't have possible or practical just a few years ago. Digital advances have given filmmakers the ability to create movies without boundaries between technologies.
