Our Rollei F:X Pro Center GND 8 (3 stops/0.9) is a so-called Graduated gray filter or Graduated Neutral Density Filter, which has a gradient tint. With graduated filters, the coating usually runs out to a certain side, but this is not the case with Center GND. Because the word center stands for that e Intensity of the tint (coating) decreases from the center of the filter in both directions on the outside and does not end with a hard cut in the middle, like the Hard GND.
Gray gradient filters (GNDs) are used for subjects where the brightness conditions have a certain gradient and therefore require different exposure. The classic place of use for the Center GND is therefore: Sunrise or sunset, in which the Sun in the middle of the picture can be seen and the brightness decreases in all directions. The Center GND ideally compensates for this scenario because it only darkens the brightest part of the image, which does not affect the image areas above and below the horizon line. In this way, magical image compositions become possible..
Our Center GND 8 is available in the same size 100 x 100 millimeters (100 mm rectangular filter system). It has a density of 0.9 and 3 stops in the middle, darkened area. A stop means that the amount of light hitting the sensor decreases by one f-stop.
