The Photoshop HDR Tone Mapping Tutorial
Before We Begin
Download the following three images to your hard drive (Right mouse click> Save As). You will be using these images to follow the tutorial.
Step 1
First, we'll need to load the three images into Photoshop. We will use the Load Files into Stack feature for this. To access this, select the File> Scripts menu and choose Load Files into Stack.
The Load Layers window should appear. In the Load Layers window, browse for the three images you've downloaded and add them to the list. Checkmark the "Attempt to Automatically align Source Images. With this checked, Photoshop CS3 will try to align the images.
Step 2
After waiting for Photoshop CS3 to process the images, you should end up with a new document with three layers. Make sure that the neutral.jpg layer is the bottom layer and the over.jpg layer is the top layer.
Step 3
Select the over.jpg layer and add a layer mask by opening the Layer> Add Layer Mask menu and selecting Reveal All.
Step 4
Open the Image menu and select Apply Image. In the Apply Image window, checkmark Invert and click OK.
The over.jpg layer should now be an invert of the image.
Step 5
Select the under.jpg layer and add a layer mask by opening the Layer> Add Layer Mask menu and selecting Reveal All.
Step 6
Open the Image menu and select Apply Image. In the Apply Image window, select the layer under.jpg, uncheck Invert, then click OK.
Step 7
We're done tone mapping and now we have the three different exposures on their own layers with their own layer mask.
Final Results
Roll over the image below to see a before and after effect of tone mapping.
Removing Ghostings
If you look closely, you may notice some ghostings due to moving objects when the image was taken.
To remove this, select the over.jpg layer and paint the area in the layer mask white.
