2) Distortion:

Corrects images where shape relationships are disrupted so that they appear as they

should

3) Chromatic aberration:

Corrects color fringing that arises around the image periphery

4) Color blur:

Corrects the blue and red color blurring that can occur at the edges of very bright

areas in images

This innovative technology ties together the lens information, camera lens system infor-

mation and image design in a comprehensive way that could be achieved only by a truly

comprehensive camera manufacturer.

At present, 29 EF lenses (lenses with built-in lens ID, focal length and distance informa-

tion) are supported.

*Also usable for RAW images taken with extender mounted on supported lens.

Depending on the EOS Digital camera on which the lens is mounted, there are 2 modes

of correction using DPP ver.3.2. In the latest models released in 2007 (EOS-1Ds Mark III,

EOS 40D and EOS-1D Mark III), the lens ID and the focal length and distance information

are recorded as supplementary information in photographed RAW images. As a result,

these cameras meet all the requirements for aberration correction. To use aberration

correction on these 3 models, simply check the boxes for the factors to be corrected in

the [Lens aberration correction] window.

On the EOS-1D Mark II

, EOS-1Ds Mark II, EOS-1D Mark II, EOS-1Ds, EOS-1D, EOS 5D,

EOS 30D and EOS Digital Rebel XTi/400D DIGITAL, the lens ID and focal length are

recorded as supplementary information in photographed RAW images, but the distance

information is not recorded. On these cameras, when one checks the boxes in the [Lens

aberration correction] window for the factors to be corrected in photographed RAW

images, aberration is corrected on the assumption that the distance is set to infinity.

To correct aberration in DPP, open the [Lens aberration correction] window (edit window

or edit window tool palette [NR/Lens] tab> click the [Tune] button) and check the boxes

for each of the 4 correction factors to be corrected. The image is then corrected and the
