Play with the history panel in Develop Module. Have a look at the snapshot function. Also try the Before/After compare view, the Y|Y icon, on the Develop tool bar. Any history state can be set as the before view. If you need details, just ask.

In addition to what Brad has suggested, if you are planning any irrevokable forks in your edit stream, you should be gin with a virtual copy and make the change to the VC otherwise if you (for example) have a B&W and back up in history to before the B&W step and make a new edit step, you will lose the old fork.

As LR is non-destructive what would constitute an irrevokable fork in a LR edit stream?

Converting to B&W is an example. If you wanted a B&W and Color edit of the same image, virtual copies are the way to go. You wouldn't make the same sequence of edits to both ... so having one edit sequence with both B&W and Color doesn't make sense.

Of course, you can always go back to the original image and wipe out all of your changes.

[/quote]Non destructive in that it does not alter the original. Image applications that do not meet this non-destructive requirement have a 'Save' function. In LR, there is no Save, only Export. History steps don't really constitute a sequence. Just a set of adjustment states that represent the sliders on the right panel as well as other adjustments like crop, brush spot removal etc. at a point in development. History just 'remembers' the state of the adjustments at those named events. Going back to a prior step and adding a new adjustment essentially instructs LR to forget all states that followed the step where you forked. The old fork disappears unless you have made a snapshot. or a VC. The snapshot does not retain history, just the state at the snapshot. VC retains its history like the master.
