Working primarily in feature films, Markus studied under Barry Ackroyd, BSC, Brandon Trost, Tak Fujimoto, ASC, Dean Semler, ASC, and Matthew Leonetti, ASC. He focused on the intricacies of filmmaking during his time with these DPs and developed an appreciation for the look of film and the art of cinematography.

Through his recent works – DETROIT (Annapurna), EXTREMELY WICKED, SHOCKINGLY EVIL AND VILE (Voltage), DIARY OF A TEENAGE GIRL (Sony Classics), THE BIG SHORT (Paramount), and THE DISASTER ARTIST (New Line), Markus learned how to take advantage of low light levels inspired by practical lighting and how to use multiple digital formats in film. The minimalist approach employed during these shoots provided actors with the freedom to improvise, a key component in his own cinematography.

Markus is a graduate of Brown University.
