This link contains an excerpt of my work showcasing digital to analog transformation.
The BlackMagic camera is great for achieving a 16mm look.
From the references below, the first one (ODD COUPLE) is shot on BMCC and transformed to an analog look. The second one (TOOM) was shot on an ARRI Amira in super 16 mode.
From SOLOMUN x JAMIE FOXX to PEDER, all films are shot on ARRI ALEXA cameras in regular mode. So these read more like a 35mm look.
COCA COLA is shot on RED and also transformed into an analog/ digital hybrid.
I strongly believe that you should know how actual analog footage behaves during color grading in order to build a proper 16mm look. Therefore I also added 4 of my favourite analog projects at the bottom.
