Lightroom Shortcut – Compare
Well as all know one of the most useful tools when editing is to see how much you’ve changed. Sometimes you find it you’ve gone over the deep end on something and need to back off because whatever was, would work better.
In Lightroom, while under the “Developer” modeule (D) 2 has the (\) can be used to switch back and forth to the before and after image of your shot. With or without any edits.
What is going on is that the image is shown as it stands, compared to the “Import” usually the initial view. What if you had 12 changes, but only wanted to see the last 6 changes to a customer as before and after and not all of the other corrections?
The trick is to move the “before” stamp to a new spot on the history. Select the step you want to be “before” and on the History item, right click and select “Copy History Step Settings to Before”. Remember, that whatever history item you have selected is the “After”. So select the next point of comparison and use the backslash key.
