The subject of RAW vignette adjustments was discussed in 2005 here:
Is Camera Raw Legal?
At that time it was said that it is, but that was before the rules re-write.
In view of the following statement in the updated Basic rules, is a vignette adjustment in RAW considered legal or illegal?
"* use RAW conversion software as long as the changes are made globally to a single file on one layer and do not create new features or effects in the process."

I reckon RAW vignette would not be legal under Basic editing rules.
If I remember correctly this great shot was DQed because of it

| The shot that you referred to was DQ'd because he used the lens correction filter in PS, not Camera Raw. |

The rule of thumb is,"if something already exists in an image and you use a tool to enhance it then it's usually ok.". If you are adding a vignette then it is likely not legal. If you are enhancing an existing vignette then you are probably ok. Removing the vignette may get you into trouble.
However, getting a ruling from the SC is probably your best bet.

Actually, it was DQ'd because the vignette was ADDED in RAW. I believe the rule of thumb is that removing a vignette in RAW is a corrective edit and falls under "preserving image integrity" (like removing noise or fixing white balance), but adding a vignette isn't allowed because it creates a new effect or feature. Any other SC wanna chime in? |

Yeah, my "Exit" image was also recently DQ'ed for adding vignette. The problem was that I knew it was illegal--I was thinking this was using "Advanced Editing" rules :-(

Actually, no, it was in ACR - "Just to clarify, it was disqualified because I added the dark corners in the .raw processing phase of the shot with Photoshop CS2 under the lens correction tab." |

In 'advanced' and 'expert' editing, however, adding a vignette with RAW, dodge and burn, gradients and/or other techniques is acceptable even if it was not previously there?

In Basic, you can't add a vignette for the reasons scalvert mentioned. In Advanced and Expert, you can use the editing tools you mentioned to add a vignette in post-processing, but it still can't create a well-defined or hard-edged shape.

Edited: for clarity.

My personal interpretation is that we don't regard color shifts or tonal adjustments on the captured image as new features in Advanced. Where you would get into trouble is if you used a vignette tool to create a hard edged shape (something that doesn't look like a vignette) or create a new shape or object with a color shift. Using dodge and burn to "invent" a beam of light coming from the clouds would also result in a DQ since the beam is a new object rather than a lighter or darker version of the existing objects. |
