I include 3 ca. 200 % crops of the same part of an image, one processed with PD2011, one processed with Raw Therapee 4.01 and one processed with Canon DPP 3.10.1.

The photodirector one has a strange hotizontal line that I have not seen before in any image, and the other raw convertors do not show it either when converting the same raw image.

The PD2011 image shows the same line in other parts of the foliage, on exactly the same horizontal position.

As PD2011 uses the Canon SDK it's strange that Canon DPP does not show the problem when converting the same raw image.

Anyone else seeing this?

Hi,
I also use Canon CR2 and never experienced this problem - are you able to share the source RAW file that shows this issue?

btw - did you use latest Version of PhotoDirector 2011 - there was a patch release recently

I installed the patch (running version 2.0.1928 on Windows 7 ultimate 32 bit fully patched)

I attach the raw image.

I didn't see this on any other image before with PD2011, but I haven't been using it all that long...
