Stern lit scenes filmed at the Park Plaza Hotel using dimmable HMI and tungsten lights rigged within balloon lights. This setup allowed him to "dial in" the color he wanted, as the blend of tones from the tungsten fixtures, wooden walls and natural daylight made it difficult to illuminate the scenes using HMIs or daylight exclusively. Stern said the period setting had little effect overall on his lighting choices because the look was mostly applied in the production design and during digital intermediate (DI), the post-production digital manipulation of color and lighting. Technicolor Digital Intermediates carried out the DI. Stern supervised most of the work via e-mailed reference images as he was in Russia shooting another film at the time. He was present at the laboratory for the application of the finishing touches.
