Pull Focus, (Longer – Focal Length/Wider – Aperture/Closer – Point of Focus)
To achieve a pull focus you need to create a shallow depth of field. This requires a long focal length (wide iris), allowing in allot of light into the lens. Therefore this is best achieved in darker environments. Facing away from the sun/light source will help. It is also useful to move the camera far away from the subject and zoom in to achieve the shot. To get a sharp focus on the subjects zoom right in to subject 1, focus the camera and mark the f.stop number, then zoom in on subject 2, refocus and mark the f.stop. Then you can zoom out to the frame you want and experiment with the transition and different speeds between f.stop.

Shooting diagonally in plain square space can create more interesting visuals in the background. It gives a more enticing scene with corners and shadows in the background rather then a flat wall. It dives the essence of dimensions in a frame. If an actor is shot against a 2 dimensional image it can often flatten the shot and give it the appearance of being superimposed.
The key source of lighting, is the dominant form of lighting (not necessarily the brightest light in the shot but the one that gives the shot its atmospheric essence). E.g if a shot contains a bright desk lamp that may be a stronger and more intense light then the windows in the background but it is not the key lighting source that determines the mood or aesthetic.
Leaving a camera on the key side of the light will create a softer and more complimentary shot. Placing the camera of the fill side of the shot (with the camera facing the light source) will mean you are shooting on the shaded side. With more shadows can come harsher view, neither is correct or incorrect it depends of the desired effect of the scene.
Eastern European traditional film, long shots, premeditated camera movement and actors blocking. Less cuts. Mor realistic, less jarring, appreciate silence, simplicity, subtle moments and movements. Pre meditated but can be restrictive when it comes to editing, have to use the takes that have been filmed, cant just cut between best segments, pick and choose. Actors will have varying performances in the different scenes
