Haze, ultraviolet, uv, skylight filters
| Light Glossary |
Film, unlike the human eye, is sensitive to some uv which adds blue and reduces visibility on distant landscapes. these filters should not be confused with fog filters, which are supposed to add "fog." a polarizing filter can also cut haze. for b&w films, orange or red filters are effective.

Visibility, английский
- The greatest distance at which it is possible with the unaided eye to recognize a prominent dark object against the horizon sky. at night, it is defined as the greatest distance at which a moderately intense, unfocused light source can be seen on the hori
- Видимость
- [1] visual range. [2] the atmospheric property that determines ability to see and identify objects. [3] in meteorology, the distance at which a standard object can be seen and identified by the unaided human eye.
- Видимость. наибольшее расстояние, на котором можно увидеть и опознать черный предмет соответствующих размеров на фоне дневного неба или в ночных наблюдениях— при общем освещении на уровне нормального дневного света (вмо). при определении ночной видимости можно использо вать вместо чёрного объекта несфокусированный свет задан ной интенсивности. инструментально оценку видимости мож но проводить путем измерения ослабления света при прохож дении им достаточно протяженного отрезка пути. результаты измерения видимости обычно представляют собой средние значения наблюдений, проводимых по всему горизонту.
- A property of a replica that indicates which members of the replica set it can synchronize with and which conflict resolution rules apply. replicas fall into three visibility types: global, local, and anonymous.
- The ability of a bluetooth device to let any other bluetooth device discover and connect with it.
- The ability of one element to see or refer to another. for one element to send a message to another element, the latter must be visible to the former.
- Said of a variable. a variable is visible if its contents can be accessed by its name. a local variable in one function might not be visible from inside another function. vi - the classic text editor on a unix machine. generally available on all unix based operating systems. the modern version of vi is vim.
- Maximum distance at which an object of defined size, brightness and contrast can be seen and recognized.
- Quality or state of being perceivable by the eye. in many outdoor applications, visibility is defined in terms of the distance at which an object can be just perceived by the eye. in indoor applications it usually is defined in terms of the contrast or size of a standard test object, observed under standardized view conditions, having the same threshold as the given object.2,6
- Quality or state of being perceivable by the eye. outdoors, visibility is usually defined in terms of the distance at which an object can be just perceived by the eye. indoors, visibility usually is defined in terms of the contrast or size of a standard test object, observed under standardized view conditions and having the same threshold as the given object (iesna 1984).
- The prominence and positions a website occupies within the organic search results.

Fluorescent filters, английский
Filters designed to compensate for weak red and excessive green wavelengths in typical fluorescent light sources. fld and flb filters can tame some of the more commonly used tube types. tip: for the new pro, tests are advisable.
Light-struck, английский
Film that has been exposed to stray light prior to processing. see: film fog. also, this craft`s equivalent of stage-struck.
