As a direct result of your feedback, ACR 8.5 has a new button designed to display a per-panel preview that is applied directly to the main view of the image! Clicking this button will reset the settings in the selected panel to their defaults. Clicking it again will reset them to the previous settings. Or, you can use the shortcut Command + Option + P (Mac) | Control + Alt + P (Win) to toggle the preview.
Image with per-panel preview “Off” (modifications made to the HSL/Grayscale panel are visible in the image area).
Image with per-panel preview toggled “On” (the HSL/Grayscale panel is set to the default settings).
Although the preview behavior might appear to look the same as it did in previous versions, this new button actually works a bit differently “under the hood”. Instead of simply showing and hiding the settings in a panel, this button actually resets the panel (clicking the button again restores the previous settings).
So, you might be asking why did we change the per-panel preview behavior? Well, since Camera Raw is not a database program (like Lightroom is), it can’t keep track of different “states” that a panel might be in. This means that in previous versions of Camera Raw, if you had toggled off the preview state of a panel, and then clicked “Done” or “Open Image”, Camera Raw would apply the slider values—even if the preview was turned off for that panel. Therefore, what you saw in Camera Raw may not have matched the resulting file. As you can imagine, when this mismatch occurred, it was not only confusing to the customer, but also unacceptable to the engineering team.
With this release, I believe the engineers have provided us with the best of both worlds; we can still use the new Before/After features (those are completely unchanged), as well as have an improved per-panel preview as a standalone feature.

While tapping the Q key will cycle through all of the Preview modes in Camera Raw in Photoshop, I primarily use the same view 95+% of the time. So that I don’t have to cycle through so many different options, I click-hold the Mode button to display the pop-up menu for Preview Preferences. Unchecking all but one of the Preview modes allows me to tap the “Q” key to quickly toggle my Before/After Left Right view on and off.
Click and hold on the Mode button to access the Preview Preferences and check your favorite view!

The other day a customer asked me how to decrease the size of Lightroom’s Preview file (yourcatalogname Previews.lrdata). Although I had previously posted this Quick Tip video (How to prevent Lightroom’s Previews File from Taking Over the Hard Drive), he noticed that when deleting files from the catalog, the preview file size wasn’t immediately reduced. Well, it turns out that there is a slight time delay because, if you simply remove an image from the Lightroom catalog, you can still tap Command + Z (Mac) | Control + Z (Win) to undo the removal and have the photo(s) appear back in the catalog. Therefore Lightroom waits to delay that sort of clean-up task until there is an idle moment (when you aren’t making changes), and then runs in the background, so that priority tasks have all the processing power they need.

In this episode of The Complete Picture (Video Tutorial – How to Optimize Lightroom 5), Julieanne shares several suggestions for hardware, software, and preferences to help optimize the performance of Lightroom. Keeping these tips in mind when setting up a new system or refining your current system will help speed up Lightroom and make you more productive.

In this video tutorial (Why Does the Photograph’s Preview Change in Lightroom and Bridge? ), Julieanne explains one of the great mysteries of Lightroom and Bridge – why Lightroom (or Bridge) displays a photograph one way and then changes the way it looks a moment later. It will all become clear with just a little information about how digital camera files are captured and displayed by different applications.

Here are a number of shortcuts to help navigate the before and after views in Lightroom’s Develop module:
• “\” toggles Before and After view full screen (one view showing at a time).
• “Y” displays Before and After (Left/Right) View. Add the Option (Mac) / Alt (Win) to toggle Before and After Top/Bottom view.
• Shift + Y toggles to Split Screen view.
• Drag and drop the name of any state from the History panel on top of the image in the “Before” preview area to compare with the current state (this can be infinitely more useful then comparing the original “Import” state!)
• Control (Mac), right mouse (Win) -click on a Snapshot to “Copy Snapshot Settings to Before” preview in Before/After view.
• Command + Option (Mac) / Control + Alt (Win) + Shift + Left/Right arrows move the After state to Before/Before state to After.
• Command + Option (Mac) / Control + Alt (Win) + Shift + Left arrow moves the After state to Before.
• Command + Option (Mac) / Control + Alt (Win) + Shift + Right arrow moves the Before state to After.
• Command + Option (Mac) / Control + Alt (Win) + Shift + Up arrow swap the Before and After state.
And, if you only want to preview the effects of a certain panel, click the toggle switch at the top of the panel to temporarily hide the panel’s effects (except the Basic panel – it does not have this switch).

“P” toggles the Preview on/off (to quickly compare before and after). However, it only toggles on and off the preview for the active panel (Basic, Tone Curve etc). In order to toggle all changes made in all panels, select the Presets or Snapshot’s panel and tap “P”.

“V” toggles Hide/Show Adjustment Brush pins and/or the tool Overlay for Graduated Filter, Spot Removal and Red Eye Removal tools.

When working with the Adjustments panel, holding the backslash key, displays a temporary preview of the unadjusted state of a document. (It’s like unchecking the Preview check box temporarily – so you have to have made a change to the adjustment for this to work.) Because of the need to distinguish a tap from a hold, there’s a slight delay before the results of the hold behavior become visible.
