Today’s Question: In several emails over the years, you’ve suggested resetting preferences in Photoshop or Bridge in order to fix a problem. If I reset the preferences however, does that mean that they would go back to the default settings and I would lose all the preference settings that I have input over time and been using? Or is this some way to save them?
Tim’s Quick Answer: Yes, resetting preferences in Photoshop, Bridge, or Lightroom Classic will cause all settings in the Preferences dialog (and Color Settings in Photoshop) to revert to their default settings, requiring you to update them manually to your preferred settings.
More Detail: For as long as I’ve been using Photoshop (which has been over thirty years!) there has been the sometimes frustrating issue of needing to reset preferences. The same issue affects Bridge and Lightroom as well. The way I describe the issue is that if the software seems to behaving in an odd way that is different from what you would normally see, there’s a good chance that resetting preferences will solve the issue.
While resetting preferences often corrects issues where the application isn’t behaving normally, it does mean that any settings you have changed from their defaults will be lost. You’ll then have to go back and manually update the settings based on your own preferences. There isn’t a way to back up your settings, other than backing up the preferences files, but that approach would prevent the reset from actually taking effect.
What I recommend is to capture screenshots of all tabs of the Preferences dialog before you reset preferences, so you have an easy reference for your preferred settings. Note that for Photoshop in addition to the settings in the Preferences dialog, resetting the preferences will also reset the settings in the Color Settings dialog.
Note, by the way, that if you’re experiencing an issue that primarily affects the way the interface is displayed or with the application crashing unexpectedly, it is also possible that disabling GPU (graphics processing unit) support will resolve the issue.
