Neutral density graduated camera filters (also known as ND grads) are clear in the bottom half with a gradual transition to the ND effect in the top half of the filter. They produce a grey neutral tone and are used to reduce light, enabling more control over exposure and depth of field without affecting colour or contrast. Neutral Density graduated filters are primarily used for light reduction in skylines or landscape photographs.
Since ND filters uniformly reduce light at all wavelengths, there is no effect of the colour rendition.
