Haida 100x150mm Red-Diamond Reverse Grad ND0.9 Filter

Haida Gray Graduated Filter ND 0.9 Reverse Grad for 100mm Filter Holder

Gray graduated filter für Haida M10mm system - can be used on almost any lens.

The 100mm system is considered the standard system für plug-in filters.
It is equally suitable for SLR cameras but also for mirrorless cameras.

With a compatible filter holder and the matching adapter ring, the filter can then be used on almost any of your lens. It just needs für each lens a matching adapter ring.

To achieve an even exposure on subjects with strong differences in brightness (e.g. land - sky), a gray graduated filter is used.

A gray graduated filter is constructed into two areas, a clear zone and a neutral gray zone. The gray zone reduces the amount of light entering the lens. The clear zone allows light to pass through unobstructed.
This makes it possible to expose the image evenly. Example: Sunset on a mountain range, the sky is very bright and the mountain dark. The gray filter zone is used to darken the brighter part of the image and then set the appropriate exposure for the darker part of the image. This ensures that the image is correctly exposed over the entire image area.

Available in different shades of gray and with different hard gradient boundaries.
Haida gray graduated filters are available from us in a wide range of variants. There are different Ausführungen with different dark gray areas. Differentiated in the gray levels and in the Verläufen thisers gray levels.

Filters with hard gradients, i.e. with a very abrupt separation between the clear and the gray zone, are suitable for motifs with a clearly defined and straight horizon, e.g. sunset at the sea.
Filters with soft gradients are suitable for subjects with a less clearly defined horizon. These are, for example, slightly hügelige mountain landscapes or landscapes in general.

Metal box für a safe storage and transportation.
The scope of delivery of the filter includes a metal box. This is perfect to transport or store the filter well protected.

The aperture reduction of ND filters is calculated as follows:

The density of ND filters is usually given in increments of 0.3.
To get the aperture reduction, first multiply the value by 10 and then divide it by 3.

0.3 x 10 = 3  | 3 = 1  Aperture
0.6 x 10 = 6  | 3 = 2  aperture
1.2 x 10 = 12 | 3 = 4  apertures
3.0 x 10 = 30 | 3 = 10 f-stops
3.6 x 10 = 36 | 3 = 12 f-stops
4.5 x 10 = 45 | 3 = 15 f-stops
