1. The first thing we have to do is to duplicate the original layer byright clicking on the layer an choosing “Duplicate Layer”. We canname our first layer “original” and our duplicated layer “black andwhite” or just “B&W”.
2. Now we have to adjust our “B&W” layer. First we will changethe layer’s blending mode to “Overlay”.Next we have to desaturate the layer. We can do this by going toImage > Adjustments > Desaturate. •Or we can use the keyboard shortcut combination Shift+Ctrl+U. •Now we’re going to invert the “B&W” layer: Image > Adjustments > Invert •Or we can use the keyboard shortcut combination Ctrl+I.
3. It’s time to add some Gaussian Blur to our “B&W” Layer. We’ll dothis by going to Filter > Blur > Gaussian Blur.Tweak the blur radius around 30 pixels. You can adjust this to fityour own taste. Anywhere between 20 and 50 pixels will create the“glow” around the edges.Now if you have followed right our CS5 HDR tutorial, you will havean image similar to this:
4. The next thing to do is to duplicate again the original layer and todrag it on top of all layers. We can name this layer “Linear”.
We have to change the layer’s blending mode to “Linear Light”. Now tweak the opacity of the “Linear” layer until you are satisfied with the final result. For my image I set it to 60%.
At the end you have to get an image that looks something likethis: I hope you like this, easy but cool Photoshop CS5 HDR Tutorial.
