The Hitech 85mm Graduated Neutral Density 0.3 Soft Edge Filter is a professional quality graduated 1 stop (2x) ND filter with soft graduation, making it the standard for general landscape shots. Hitech Neutral Density Graduated filters enable the shooter to adjust exposure without affecting colour balance. For example, when photographing landscapes in which the sky is much brighter than the foreground, placing the neutral density part of the filter onto the sky in the frame will reduce the sky exposure without affecting the foreground. This enables cloud detail to be kept correctly exposed in the picture. These 84x110mm filters fit in the Cokin P filter holder and are manufactured from the highest quality optical grade polyester resin.
Coral Filters can be used as general warm-up filters, or provide special effects. The Lee Coral Filter is a pinkish warm-up filter, redder than the 81 series. As the number increases, the amount of colour temperature correction increases.
