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.
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 N , 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
