Cinematography Cheat Sheet
The core ideas of Cinematography distilled into a single, scannable reference — perfect for review or quick lookup.
Quick Reference
Exposure Triangle
The interrelationship between aperture (f-stop), shutter speed (shutter angle), and ISO (sensor sensitivity or film speed) that determines the overall brightness and look of an image. Adjusting one element requires compensating with the others to maintain proper exposure.
Depth of Field
The range of distance within a scene that appears acceptably sharp in the image. It is controlled primarily by aperture, focal length, and the distance between the camera and the subject. A shallow depth of field isolates a subject from the background, while a deep depth of field keeps foreground and background elements in focus.
Color Temperature
A measurement in degrees Kelvin that describes the hue of a light source, ranging from warm (lower Kelvin, around 2700K for tungsten) to cool (higher Kelvin, around 5600K for daylight and above for overcast sky). Cinematographers use white balance settings and colored gels to control the color cast of a scene.
Three-Point Lighting
A foundational lighting setup using three light sources: a key light as the primary illumination, a fill light to soften shadows created by the key, and a back light (or rim light) to separate the subject from the background. Variations of this setup form the basis of most cinematic lighting designs.
Focal Length
The distance in millimeters between the optical center of a lens and the camera's sensor or film plane when focused at infinity. Shorter focal lengths (wide-angle) capture broader fields of view with exaggerated perspective, while longer focal lengths (telephoto) compress space and narrow the field of view.
Camera Movement
The deliberate physical motion of the camera during a shot, including panning, tilting, dollying, tracking, craning, and handheld movement. Each type of movement carries different emotional and narrative connotations and can guide the audience's attention or create a sense of energy, unease, or elegance.
Aspect Ratio
The proportional relationship between the width and height of the image frame. Common cinematic ratios include 1.85:1 (standard widescreen), 2.39:1 (anamorphic scope), and 1.33:1 (the classic Academy ratio). The choice of aspect ratio affects composition, the visual weight of the frame, and the audience's sense of space.
High Dynamic Range (HDR)
An imaging approach that captures and reproduces a wider range of luminance levels between the darkest shadows and brightest highlights than standard dynamic range imaging. In cinema, HDR acquisition and display allow cinematographers to preserve detail in both extremes of exposure simultaneously.
Mise-en-Scene
A French term meaning 'placing on stage,' referring to everything that appears within the frame: set design, lighting, costume, actor blocking, and composition. While broader than cinematography alone, the DP works closely with the director and production designer to ensure all visual elements are cohesively captured.
Color Grading
The post-production process of adjusting and enhancing the color, contrast, and overall look of footage to achieve a desired aesthetic. Modern digital color grading tools like DaVinci Resolve allow precise control over every aspect of the image, from global color shifts to targeted adjustments on specific regions.
