The famous filmmaker Stanley Kubrick owes majority of his cinematic genius through his years of experience as a photographer. Firstly, he shot for magazines such as Look magazine, hence training his eye for visualization. Kubrick's fondness for the camera has led him to be rather incredibly creative with his gear.
It's not the filmmaker's primary job to know camera tech -- this is the cinematographer's job -- but Kubrick was more than educated of it, to a point he would even tinker and modify many lenses,, which would become helpful for his filmmaking.
Here, Joe Dunton of the Frankfurt Museum shows us Kurbrick's beloved lenses and explains their value to the late filmmaker.
