Image Dust Off

❏ Creating Image Dust Off Reference Photos

To create an Image Dust Off reference photo for cameras that lack an Image Dust Off reference photo

option:

❏ Creating Image Dust Off Ref Photos (D1-Series and D100 Cameras)

Image Dust Off is available only with images taken with a CPU lens. Image Dust Off references photos can

be created using cameras with an Image Dust Off reference photo option, D100 cameras, and D1X or

D1H cameras from firmware version 1.10 or later. Images Dust Off reference photos can not be created

with other cameras or with earlier versions of the D1X or D1H firmware. Image Dust Off ref photos taken

with the D100, D1X, or D1H have the extension “.nef”; do not change this extension.

❏ Camera Shake

A slight amount of blurring caused by camera shake will not affect Image Dust Off ref photos.

❏ Image Dust Off

Image Dust Off only affects relatively featureless areas of the image.

❏ Reusing Image Dust Off settings

Before pasting or loading Image Dust Off settings for another image, be sure that the image was created

with the same camera used to record the Image Dust Off reference file. If the reference file was created

with a different camera, a warning will be displayed.

Select a CPU lens

Mount a CPU lens on the camera. It is recommended that you use a lens with a focal length of at

least 50 mm. If you are using a zoom lens, zoom in to the maximum telephoto position.

Adjust the camera settings

Choose the following settings in the order shown below:

a. Sensitivity (ISO equivalency): choose the minimum setting

b. Image quality: choose NEF (RAW)

c. Exposure mode: choose aperture-priority auto (A)

d. Aperture: choose the minimum aperture (largest f/-number)

e. Focus: choose manual focus and set focus to infinity

Take a photograph

With the lens about 4 inches (10 cm) from a featureless white object, such as a wall, frame the object

so that it fills the viewfinder and take a photograph. The resulting Image Dust Off reference photo

will be recorded as an NEF (RAW) image.

Transfer the photograph to the computer
