Image Dust Off

Dust off ref photo is available with CPU lenses only. A lens with a focal length of at least 50mm is recommended. If using a zoom lens, zoom all the way in.

The same reference image can be used for photographs taken with different lenses or at different apertures. Reference images can not be viewed using computer imaging software. A grid pattern is displayed when reference images are viewed on the camera; histograms and highlights are not displayed.

Image Dust Off is used to reduce the effects of dust in NEF (RAW) photographs. See the Capture NX manual for more information.
