The Rollei F: X per hard GND 8 (3 stops/0.9) is one Gray gradient filter. The abbreviation GND stands for Graduated neutral density filter, which means a gray filter with the transition from tint to transparency. In the case of course filters, the coating expires to one side. The word 'hard' stands for the fact that the filter has a very hard transition from the dark to the transparent area.
For these motifs you can use the Hard GND:
- Recordings by the sea
- Sunset or tap with a clear horizon line
- Motifs with a clear horizon line and great imbalance of the brightness
GNDS are used (unlike normal ND filters) for motifs in which the brightness conditions have a certain course and therefore need different exposure for an evenly exposed image. The classic location of a hard GND8 is, for example, a sunset on the beach, in which the foreground does not have to be darkened, but the background is still very bright due to the sun and must therefore be darkened. The Hard GND8 compensates for such scenarios.
You can get our hard gnd8 in size 100 x 150 millimeters (100 mm filter holder system). He has a density of 0.9 and 3 stops. A stop means that the amount of light that is incurred on the sensor decreases by one aperture level.
