It seems to me that the rules and guidelines around allowable post processing techniques have been greatly [strike]reduced[/strike} simplified. They now state simply that you may "-use cloning or similar tools to remove unwanted objects from your image. Objects removed must be replaced with with what actually would be visible if the distracting object were not there in the first place.
-use cloning or similar tools to fill in gaps around the perimeters of panoramic or perspective-corrected photos with appropriate bits to continue the interrupted image."

I thought there used to be something about other tools commonly used in post processing?? Something more to the effect of "you can use just about any tool available to you in Photoshop or similar programs".

My specific "question" at this time has to do with use of the transform tools. Can you use them pretty liberally and can you use them selectively?

The generic answer to the question is, yes, you can use them pretty liberally. Like any other tool, their use is only prohibited if the end result violates another rule. That is frankly pretty hard to do. Selective application, again, is only subject to the need to stay within the rules for the final result.

Thanks. Specifically, I had in mind selecting part of an image and using the free transform tool to either stretch or shrink the selected area. No canvas would have been added. Everything that was originally in the image would still be there; nothing that had not been in the image originally would have been added; but the relative proportions of the "sections" would have changed significantly.

This has been permitted in the past to "correct" for lens or perspective distortion and make something/a scene look more "natural" ... I think under Standard you can introduce distortion and the voters will decide if it was a good idea ...

So I suspect that the answer to my question is no :)

Because of the image, voters would have been unable to tell (and, thus, to "decide"). The "scene" would not have looked more - or less - natural; it just would have looked entirely different.

I think what you describe is (probably?) "legal" -- whether a good idea score-wise is a separate question.

I hope you get another opinion or two ...

I'm pretty sure that what you are proposing is entirely legal, however if you'd like us to take a look at it, open a ticket and attach before/after images, and we can review.
