In advanced editing, can I apply gaussian blur to the entire image, then selectively erase portions of the blur, essential creating shallower DOF than actually exists?

'You may: ...apply filters, effects, dodge & burn, and other tools to all or part of your entry,'

But do not apply enough blur to misconstrue the viewers opinion of the image composition.
Quote from Advanced Editing Rules -
"# apply filters, effects, dodge & burn, and other tools to all or part of your entry, but NO new shapes or features may be created in the process."
# use ANY editing tool to move, remove or duplicate any element of your photograph that would change a typical viewer̢۪s description of the photograph (aside from color or crop), even if the tool is otherwise legal, and regardless of whether you intended the change when the photograph was taken.
# use ANY editing tool to create new image area, objects or features (such as lens flare or motion) that didn't already exist in your original capture.
# use distortions to create new effects or radically alter objects.
Quote from Basic Editing Rules -
# use filters or stand-alone utilities designed to preserve image integrity (such as Neat Image, Unsharp Mask, Dust & Scratches, and color correction tools). These filters must be applied uniformly to the entire image, and must not be used in such a way that their use becomes a feature. No "effects" filters may be applied to your image, with the exception of Noise and Gaussian Blur.
# use ANY editing tool to create new image area, objects or features (such as lens flare or motion) that didn't already exist in your original capture.

No. Previous discussions have indicated if the increased DOF creates an emphasis on the subject that wasn't present in the original it is significantly changed. I'll see if I can find a thread discussing this.

It would be covered under one or both of these rules that Judi quoted:
(You may not:)
# use ANY editing tool to create new image area, objects or features (such as lens flare or motion) that didn't already exist in your original capture.
# use distortions to create new effects or radically alter objects. |

If you are right I have about 15 DQs coming.
I have used a like minded technique many times in Advanced editing. The objective was to blur the background more that it was in the original image to create a shallower DOF.
I believe this is specifically allowed in Advanced Editing.
SC- can you confirm?

Perhaps I should clarify. :D
The thread I was looking for (not finding it) was created by labuda and asked if he could blur the background aroudn the subject. The ruling was that if the blur went far enough to obscure (create bokeh) it was not allowed. This is very similar to what is being asked here -- if the creation of a shallower DOF involves obscuring the background.
BTW, I remember the thread mainly because it went off-topic with a question about using multiple RAW conversions and was the first thread to contain an official ruling allowing such. It was a couple of years ago -- but all this is if my memory is serving me correctly today. :D

| I think it is a matter of how much you use. I have done it and been validated before. but if you used so much to severly alter the look of your photo you may be riding the line. |

The ruling on this has pretty much always been that you can selectively blur a background as long as:
- You don't so severely blur it that it becomes featureless (because then you've removed features)
- You don't add radial (zoom) or motion blur that was not there before. |
