Zone 5

Zone 5

In photography, Zone 5 refers to a middle gray tone in Ansel Adams’ Zone System, a technique for controlling exposure and development to achieve desired tonal values in a photograph. The Zone System divides the tonal range of a scene into 11 zones, from Zone 0 (pure black) to Zone 10 (pure white). Zone 5 represents a neutral, 18% gray reflectance, which is the midpoint of the tonal scale and typically corresponds to a correctly exposed average subject, such as a gray card or average skin tones.

Key points about Zone 5
Exposure: It’s the standard reference for light meters, which are calibrated to render a subject as this middle gray tone. For example, if you meter a scene and expose as the meter suggests, the subject will appear as Zone 5 in the final image.
– Tonal Context: Zone 5 serves as the anchor for placing other tones in the image. Photographers use it to decide how to adjust exposure to shift lighter or darker tones to other zones (e.g., placing a highlight in Zone 7 or a shadow in Zone 3).
– Practical Use: When using the Zone System, a photographer might meter a subject they want to appear as middle gray (Zone 5) and then adjust exposure or development to ensure other parts of the scene fall into desired zones for contrast and detail.

In digital photography, Zone 5 still applies as a reference for proper exposure, often used in histograms or exposure metering to ensure a balanced image. For instance, exposing a gray card to fall around the middle of a histogram aligns it with Zone 5.

John 1

1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
4 In him was life; and the life was the light of men.
5 And the light shineth in darkness; and the darkness comprehended it not.
6 There was a man sent from God, whose name was John.
