B W Graduated Neutral Density Filter
- Colorless filters that reduce the amount of light in controlled degrees. (Camera/Lighting)
- Represents a measure of how dark the color is. The lightest possible value corresponds to a neutral density of 0.0 and is equivalent to pure white; while the value 3.294 is roughly equivalent to the sum of 100% of each of the CMYK inks and can be interpreted as Registration Color.
- In photography and optics, a neutral density filter or ND filter can be a colorless (clear) or grey filter. An ideal neutral density filter reduces and/or modifies intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition.
- calibrated: marked with or divided into degrees; "a calibrated thermometer"
- gradational: taking place by degrees

More long exposure experimentation. I think I'm getting a load of IR through my hi-tech graduated neutral density filters - that's the reason this one is B&W, I couldn't get the red out of the sky without it looking terrible. I've never noticed it in normal usage, but it's a big deal for these long exposures in the middle of the day. Though, I kind of like the moodiness of this image.
Desolate Beauty with a Graduated Neutral Density Filter
B+W #502 filter, to be exact. I should have kept this filter on, but I was unfamiliar with using one. Oh well, next trip. Also need a filter for my AF-S Nikkor 18-200mm 1:35-5.6 lens which is a different size (72mm). Looks like I used that lens for these shots.
