image effects in photoshop *can* be reversible, but they are not always because photoshop is at its core, a pixel editor. you have to take additional steps for something to be non-destructive. it's not that hard but simply opening a file and doing something will not be reversible.Eric StevensSandman
What Floyd was saying was that High Pass Filter sharpening and Gaussian Blur are basically the same process and that process is fully reversible.
All image effects in Photoshop are 100% reversible.
on the other hand, all operations in lightroom are reversible because it's non-destructive.
correct. with *his* tools, it's not reversible.Eric StevensSandman
He was also saying that Unsharp Mask is not fully reversible and does involve the loss of information.
Yes, that's the incorrect statement he did that we are making fun of - that is, after we corrected him and he kept making the incorrect statement.Eric StevensSandman
None of this has got anything to do with the use of the sidecar files used by Lightroom, DxO, NX2, NX-D, Darktable or any other application.
Of course not. But all of those have the ability to reverse the effect of any transformation of an image - hence; reversible.
Simple English.
It is true that for Floyd, who uses rudimentary tools that aren't as capable as modern tools, most of what he does is not reversible, but the rest of the world - and serious photographers - aren't limited by his kindergarten tools.
with modern and more sophisticated tools, that obstacle has been removed.
