Today’s Question: Is there an easy way to determine which adjustments in Lightroom Classic have been changed from their default values?
Tim’s Quick Answer: There are indicators for which adjustment categories have been changed from their default settings, and which specific adjustments have been modified.
More Detail: The first thing to look at is the eye icon that appears to the left of each section heading on the right panel in the Develop module. That eye icon will appear more bright for sections that have adjustments that have been changed from their defaults, and more dim for sections where all adjustments are at their default values.
Another indicator can be found in conjunction with the buttons for the categories of adjustments on the small toolbar below the histogram. These include the Edit tab, the Crop tool, the Remove tool, and others. A small dot appears below the icon for the buttons that have adjustments applied beyond the default settings.
For individual adjustments you can determine if the value has been changed from the default by looking at the numeric value for the adjustment to the right of the slider. If the value differs from the default, the numbers will appear brighter, and if the adjustment is at the default value the numbers will appear more dim.
You can, of course, also refer to the History section of the left panel to see which adjustments have been applied, including an indication of how much the adjustment was changed by and the new value for the adjustment.
