A graduated neutral-density filter, also known as a graduated ND filter, split neutral-density filter, or just a graduated filter, is an optical filter that has a variable light transmission. Typically half of the filter is of neutral density which transitions, either abruptly or gradually, into the other half which is clear. It is used to bring an overly-bright part of a scene into the dynamic range of film or sensor. For example, it can be used to darken a bright sky so that both the sky and subject can be properly exposed. ND filters can come in a variety of shapes and sizes and densities and can be used in all types of photographic applications from still photography, motion photography and scientific applications.

  • Šedý přechodový filtr, známý také jako šedý neutrální přechodový filtr, nebo také jako šedý přechodový ND filtr, je optický filtr ve fotografii, který má proměnlivou propustnost světla. Filtr slouží především k vyrovnání kontrastů scény, například nadměrného jasu příliš světlé oblohy. (cs)
  • Grauverlauffilter oder GND-Filter (aus dem Englischen graduated neutral density filter) sind ND-Filter, die zu einem Ende hin ganz transparent werden. Sie werden häufig in der Landschaftsfotografie eingesetzt, um eine Überbelichtung des Himmels bei korrekter Belichtung des Bodens zu vermeiden. Der Effekt eines GND-Filters kann außer bei HDR-Aufnahmen nur sehr beschränkt durch elektronische Bildbearbeitung simuliert werden, da in überbelichteten Stellen Bildinformationen in der Regel verloren sind.

  • Un filtro a densità neutra graduato o filtro digradante o filtro GND (dall'inglese Graduated Neutral Density), in fotografia, e più in generale, in ottica è un filtro che riduce uniformemente l'intensità della luce in tutte le sue lunghezze d'onda e lo fa in maniera costante in senso orizzontale e digradante in senso verticale. (it)
  • Een grijsverloopfilter is een fotografisch filter. Het is een grijsfilter waarvan de optische dichtheid over een richting (bij gebruik meestal van beneden naar boven) verloopt. Het filter wordt ook wel aangeduid met GND-filter (graduated neutral density filter). (nl)
  • 渐变中灰滤镜（英語：Graduated Neutral Density Filter，简称中灰渐变镜或GND）是常用的物理滤镜中的一种。其作用为在大光比摄影（主要为风光摄影）时弥补相机感光元件（胶片或传感器）原生宽容度不足，使图像的暗部与高光部均合理曝光（详见）。 在胶片时代，GND用于在风光摄影中尽可能还原肉眼所见美景；而到了数码摄影时代，初期传感器产品较小的动态范围可通过GND进行弥补，而数码暗房的出现也使得光比控制有了更多方法，如高动态范围成像（HDR）；但仍然有玩家认为物理GND相较于数字后制方法保留更多的细节，以及更少的噪点。 (zh)

ND filters can come in a variety of shapes and sizes and densities and can be used in all types of photographic applications from still photography, motion photography and scientific applications. Center-spot filters are ND graduated filters that are slightly opaque in the center and are clear at edges. These are used for special effects or to compensate for light falloff that is natural with large optics. (en)
