There are a multitude of ways to build up your own Cinematic Reference Library. I’ve talked about created your own cinema library. I’ve been using Evan E. Richards website for years. My VFX/concept artist friend, Adam J. Ely recommended it to me long, long ago. It’s been a phenomenal resource and has been a trusty go-to tool for me. Whenever I’m looking for inspiration or to do composition/lighting studies.
There is now a newer website called SHOTDECK. It’s in Beta mode now but you can email them to be added to their website. It has an amazing catalogue of films and search parameters. I first heard of it from Jan Urschel. Here is a link to his free youtube link talking about it in more detail.
Both sites are great for you to search out key cinematographers and top visionary films.
Here’s a little run thru using both.
