A few weeks back, I shared with you my trick for viewing a Before version of an image that’s being editing in Photoshop.
You can view Before and After versions of a photo in Camera Raw too. In fact, Before and After previews are built as native functions directly into Camera Raw interface.
So, whether you are using the plugin or the filter, you can switch between before and after views with the touch of a button. And you can see before and after views in three different configurations: side-by-side, top-and-bottom and split view.
The Before and After views can be accessed using the four buttons found just underneath the preview window.
The right-most of these four buttons allows you to toggle the Camera Raw adjustments for the current, visible panel on and off. So if the Basic panel is currently selected, clicking on the right button will reset the values in the panel to their default values. Clicking the button again will reset the values to their previous settings.
You can also use the keyboard shortcut Ctrl + Alt + P on a PC/Cmd + Opt + P on a Mac to toggle the settings.
The second button from the right is the Copy button. It lets you copy the current settings (in the After view) to the Before view.
You can also use the keyboard shortcut Alt + P on a PC/Opt + P on a Mac to copy the settings. Or use Alt + Shift + P on a PC or Option + Shift + P on a Mac to copy the settings for all selected images.
The third button from the right is the Swap button. Use it to swap the settings between the Before and After views.
You can use the keyboard shortcut P to swap settings between the two views. Or use the keyboard shortcut Shift + P to swap settings for all selected images.
The left-most button is the Mode button. By repeatedly clicking on this button you can cycle through the various Before/After views. Or, you can use the keyboard shortcut Q to cycle through the views.
Clicking and holding this button lets you view the various Previews.
You can also access the Preview Preferences from this button.

We've seen how managing the ISO setting allows you to control the amount of grain that shows in your photos. But it does more than that. Understanding and working with the ISO setting gives us added flexibility in terms of setting the other two exposure settings–aperture and shutter speed.
The bottom line is that ISO is an important and useful tool, and one that you will want to be comfortable with if you are looking to take creative control of your exposure.
