How to Open Multiple Versions of a Single RAW Image in Photoshop
RAW images contain data beyond the standard histogram. In other words, you can open in Camera RAW and the shadows or highlights can appear to be missing. By adjusting the sliders the missing data is brought back to life.
The purpose of this technique is to show you how to bring multiple versions of a RAW image into Photoshop for optimal compositing.
Open a RAW image in Photoshop (File > Open).
Make sure the Preview checkbox is selected and click the Basic icon.
By adjusting the sliders, you find that one setting works for the foreground and a second exposure is necessary for the sky and the mountain in the background.
Set the sliders for the foreground, then press Shift and click Open Object. Holding the Shift key changes the button from Open Image to Open Object.
In the Layers panel, right-click the name of your new Smart Object layer and choose New Smart Object via Copy. A new totally independent Smart Object layer is created.
Name the upper layer Foreground and the lower layer Sky.
Double-click the Sky icon to open the Camera Raw settings. Adjust the Exposure slider in the dialog box to darken the sky. Press OK to return to Photoshop.
Add a Layer Mask to the Foreground layer. Using a low opacity black brush, paint in the Layer Mask to expose the Sky layer below.
