remove the misunderstanding: there is no brighter and darker in an exposure triangle. the entire point is that if any one point in your triangle correponds to a correct metering, you can move to any other part and your metering will still be correct: 04:05, 31 August 2017: 512 × 461 (165 KB) WClarke: add 800 ISO and changed aperture values
NFPA 704 safety squares on containers of ethyl alcohol and acetone. "NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association.
The Additive system of Photographic EXposure proposed in the 1960 ASA standard for monochrome film speed, ASA PH2.5-1960, extended the concept of exposure value to all quantities in the exposure equation by taking base-2 logarithms, reducing application of the equation to simple addition and subtraction. In terms of exposure value, the left ...

An early application of exposure compensation was the Zone System developed by Ansel Adams and Fred Archer. [3] Although the Zone System has sometimes been regarded as complex, the basic concept is quite simple: render dark objects as dark and light objects as light, according to the photographer's visualization.
Exposure is a combination of the length of time and the illuminance at the photosensitive material. Exposure time is controlled in a camera by shutter speed, and the illuminance depends on the lens aperture and the scene luminance. Slower shutter speeds (exposing the medium for a longer period of time), greater lens apertures (admitting more ...
Implementing job rotation or work-rest schedules to limit individual exposure. Establishing a preventive maintenance program to ensure equipment is functioning properly. Scheduling high-exposure tasks during off-peak times when fewer workers are present. Restricting access to hazardous areas. Assigning tasks only to qualified personnel.
Occupational exposure banding has been used by the pharmaceutical sector and by some major chemical companies over the past several decades to establish exposure control limits or ranges for new or existing chemicals that do not have formal OELs. [2] Furthermore, occupational exposure banding has become an important component of the Hierarchy ...
