Question about Pincushion Correction in Canon DPP

Ok, shot the below picture with the EF-S 18-200mm at 18mm. Obviously, I get the famous pincushioning. So I went into Canon DPP to correct it. However, I had already done pp on this file (in Lightroom) and it doesn't seem to be taking the changes from Canon DPP. I thought the software--Canon DPP--does its thing on the RAW file. Since editing a RAW file only adds metadata to the file, I figured it would still show the changes I saved in Canon DPP. Or am I missing something?

Here's the photo...

Thanks a bunch. I'm a bit confused here...

Only one program can edit a RAW file before it becomes....not a RAW file. You'll have to convert to TIFF and then do more edits from there.

btw...that's barrel distortion

Oops, sorry, always get the two mixed up.

The Canon DPP software claims to be able to correct this (also read about it elsewhere). It does seem to correct it, just doesn't seem to carry over to LR. Am I just wrong on the meta data part?

Gadget Rick,

Only DPP can read it's own "sidecar file", as already explained, you must "Convert and Save" before the corrections can be read by a third party programme. I'd suggest a 16 bit TIFF.

Ah, ok, so I need to do the RAW to TIFF conversion in DPP to save the changes? Sorry, I totally forgot LR actually does its own RAW conversion.

Making a little more sense now...

Thanks.

Ok, fixed it with a combination of PT Lens plugin and the Distort filter in PS. Here's the product...
