As a professional cameraman for 27 years and a Steadicam Operator for 20, I can say with a fair degree of confidence that Orson Welles didn’t know jack shit about the photographic techniques used in Citizen Kane until a gentleman named Gregg Toland taught them to him. He knew a LOT about theatrical lighting, and some about film set lighting and composition, this is true. He did not bring much in the way of technical advances to this project. Not at all.
Gregg Toland’s Wikipedia cite isn’t bad. It briefly outlines the incredible contributions that this artist made to cinematography, and to Cinema.
From the much-vaunted deep focus photography to complex optical composites to low-angle framing that showed ceilings to elaborate crane work, Mr. Toland was an innovator and a visionary. Not only technically original in his approach and designs, he had a background that gave him a foundation in composition, lighting and the chemistry of film.
If one were to read The Making of Citizen Kane, the degree to which Gregg Toland educated Orson Welles and collabroated with his young protegé is obvious.
Welles was a genius and like many geniuses, a part of his gift was finding the best people and surrounding himself with them. In Gregg Toland, he found a visual mentor and artist whose skills were unparallelled.
I’ve shot stuff on the floor and have sat there looking around wondering how the HELL to light myself out of the corner I’d put myself in by suggesting severe low-angled shots. One things of Toland at these moments.
Deep focus today is much easier to achieve than it was in the era of Citizen Kane. Film emulsion is so much faster and prime lenses are capable of holding a crisp image wide open ( typically T 1.3 or thereabouts on a Cooke or Panavision or Zeiss prime ). Back then, such things were amazing to behold.
Mr. Toland achieved the look by brute force. He lig those sets with a footcandle amount SO much greater than the rule of the day, in order to get the deep focus.
On the other hand, Kubrick got extreme low-light lenses with the capacity for extreme deep focus by doing his homework and being technically brilliant, just as Mr. Toland was. This article on the lenses and cameras highlights the process.
Optics and film stocks had come a long way from 1940 to 1973…
