F:X Pro Reverse GND8 rectangular filter - Graduated gray filter 100 mm

F:X Pro Reverse GND8 square wave filter

Of the Rollei F:X Pro Reverse GND 8 (3 stops/0.9) is ours reverse Graduated Gray Filter . GND stands for Graduated Neutral Density , which means a filter with transition from tint to transparency. Some of these filters have a neutral gray coating, which means that differences in brightness in the image can be compensated. Normally, the coating on GND filters would run out to one side. However, reverse means that the course of the tinting (coating) is reversed. This means that the coating is particularly strong in the middle of the filter and is soft on one side of the filter, but very hard on the other side.

The F:X Pro Reverse GND8 can be used for these motifs:

• sunrise and sunset
• beach motifs
• Subjects with a horizon where there is a lot of brightness in the center

GNDs are used (unlike normal ND filters) for motifs in which the brightness conditions have a certain progression and therefore require different exposures for an evenly exposed image. The ideal place to use a reverse GND would be, for example, an image in which the sun can be seen and where clear lines dominate the image.

We offer our reverse GND 8 in the Size 100 x 150 millimeters (100 mm rectangular filter system) on. It has a density of 0.9 and 3 stops in the middle, darkened area. A stop means that the amount of light falling on the sensor is reduced by one f-stop.
