Sharpening
You may decide to use an anti-aliasing filter instead of the included IR filter. The anti-
aliasing filter (an optional accessory) is an optical filter that is mounted in place of the IR
filter. This filter improves overall image quality at the expense of a small loss of sharpness
in the image. In general, sharpen the image when the anti-aliasing filter is installed. There
may be special situations where you will not want to sharpen.
When you use KODAK PROFESSIONAL DCS Photo Desk with your camera, you can
specify whether you want the image sharpened.
The anti-aliasing filter uses optical design to reduce or eliminate the high-frequency image
patterning problems associated with single-shot digital capture and interpolation. The
optical effect causes a small change in how lenses perform compared to cameras without
the filter installed. The auto-focus capability adapts to the presence of the antialiasing
filter and will compensate for any variations under normal use.
If you choose Manual focus, be advised that zoom lenses experience a shift in the focus
point as the focal length of the zoom is changed. If you zoom into your subject matter for
close focus, and then zoom out to compose your image, the focus point will change. This
is easily remedied by only focusing at the zoom setting that you will capture the image
with, or reverting to auto-focus and allowing the focusing computer to accommodate the
anti-aliasing filter’s optical effect.
