Ansel Adams Zone System: Modern Practical Mapping from Zone 0 to Zone X
Inheriting the core heritage of tone control from Ansel Adams, the master of landscape photography, the system breaks down 11 tone zones from absolute black (Zone 0) to absolute white (Zone X) to open up the mapping adjustment of modern digital dynamic range.

1. Adams standard definition table of 11 tone zones (Zone 0 to Zone X)
| Exposure partition | Tone name | Corresponding details and texture of real natural objects | Modern digital 8-bit RGB grayscale reference value |
|---|---|---|---|
| Zone 0 | Extreme Pure Black (Pure Black) | The unexposed film base, the absolute black abyss without a trace of light | RGB: 0 - 5 |
| Zone I | Near Black | A slight departure from pure black, a low-light night where details are almost imperceptible to the naked eye | RGB: 6 - 25 |
| Zone II | Very dark and detailed (First Texture) | Deep shadow edges that can vaguely distinguish the material | RGB: 26 - 50 |
| Zone III | Rich Dark Shadows | Dark hair, black suit fabric texture, deep details in dense tree shadows (film metering anchor) | RGB: 51 - 85 |
| Zone IV | Dark Gray | Brown skin, dark cement floor, lush dark green leaves | RGB: 86 - 115 |
| Zone V | 18% Neutral Gray (Middle Gray) | Camera light meter restoration baseline, clear and cloudless Arctic sky, half of the reflectivity of the back of the hand | RGB: 116 - 145 (approximately 128) |
| Zone VI | Brighter light gray (Light Gray) | Caucasian/East Asian healthy light-received facial skin color, concrete pavement in the sun | RGB: 146 - 180 |
| Zone VII | Pale Highlights | Light gray plaster, snow light shadow, white shirt fabric texture | RGB: 181 - 210 |
| Zone VIII | Delicate Highlights | White wedding dress lace reflective micro-details, bright white snow texture in the sun | RGB: 211 - 235 |
| Zone IX | Near White | Dazzling reflections and snowy high-gloss whitening areas that almost lose texture | RGB: 236 - 250 |

2. The two practical steps of the regional exposure method: "fixing and developing"
- Step 1: Place the dark part in Zone III (Placement): In a large scenery scene, use spot metering to measure the dark side of the deepest part of the rock. The camera meter will calculate it as Zone V (18% gray) by default. On this basis, the photographer took the initiative to lower the exposure by two stops (-2 EV), which successfully "placed" the rock accurately in Zone III, ensuring that the dark parts were both textured and deep.
- Step 2: Read the highlights and determine the contrast (Fall & Expansion/Contraction): At this time, use spot metering to aim at the white clouds in the sky. If the white clouds are measured to fall in Zone VIII, it means that the natural light ratio perfectly matches the film latitude (Normal normal development N); if the white clouds fall in Zone "Downshoot" to reduce highlight contrast and achieve perfect dynamic range compression.
