nospamThat's important to a rational understanding of the role of a fully reversible process. The exceptions I referred to above are the few editing functions which are fully reversible e.g. Gaussian blur and HPM. --

Sure it is, only in another sense than old Photoshop. Every single adjustment you make in LR are applied to the pixels and saved to disk as a preview image. Difference is that the original file is always kept intact so every step is fully reversible.
It's not made to the original image: it's made to what I have described as a (reduced size) simulacrum of the original image.
it's *always* rendered from the original image data.nospamSandmanEric Stevens
In fact - using smart filters in Photoshop is *less* of a pixel editor than LR these days, because the pixels are never touched, it's all kept in RAM and the resulting image is never saved to disk until you export/save it. Also, fully reversible of course. :)
With few exceptions, once you have made the changes and saved/exported the image, you cannot reverse the changes *in*the*exported/saved*image*.
nobody said that could be done.
