Jim, I typically shoot RAW so there is always some degree of post processing (PP) involved, even if it's just my basic preset that is tailored for each camera body.
My adjustments are typically white balance, tone (exposure/shadows/highlights/black level/white level), sharpening, vignetting. I'll apply local tone adjustments with masks. I tend to set the camera to the flattest contrast curve, default sharpening, and many times auto white balance, and chimp the color histogram to see if I clipped any channels. I view the in camera file as simply a container for capturing as much data about the scene in front of me that I can.
In LR I'll use the HDR and photo merge, though I already have this in mind when I take the shot. I'll use the color mixer and color grading tools in LR to make the image more pleasing to me, predominantly to warm up shadow areas that are too "cool" based on the white balance used for the majority of the scene, and sometime to draw more out of certain colors with certain cameras. For example, all of the standard LR profiles will oversaturate and loose detail in the bright yellows and reds when I shoot with my micro four thirds setup.
I'll clone out items like "garbage" that's temporary and not part of the scene (especially landscapes) like pop cans, cigarette butts, bottles, wrappers etc that would be gone with the next windstorm or usual maintenance activities. If it's an errant branch that is isolated at the edges of a frame I may clone that out as well, though usually I try to fix that by changing my shooting position.
Beyond that I've always disclosed other manipulations when posting a picture. I've used tools for:
1. powerline removal
2. experimented with sky replacement (and pretty much don't like it and will not use it again, it may be my skill set but the results has never looked right to me)
3. generative replace or remove if simple cloning won't fix the "garbage" issue described above (though I'm on the fence about the need needing to disclose this)
Up to this point I've been firm about not adding things that were not there, or removing things other that as stated above. I don't see that changing, but I've settled for disclosure if I ever do that. (Now that I think about it, I've done exactly one shot where I used generated sunstar spikes with disclosure).
