Another method that we can automate our shadow creation is by adding our filters and noise to an automatic action. If we're creating a manual shadow, we're still going to have to do the initial drawing and painting of the shadow as you see here. After that, I can automate the rest of the features. First, I want to make sure that I've changed my shadow to a smart object and again, I can do that by right clicking and just converting it to a smart object. Then, I'm going to set up a new action that I'm going to call shadow.
Everything I do now, again, is going to be recorded. So, I'm going to go through the same steps we went to in an earlier movie. By going to Filter>Blur>Gaussian Blur and applying the appropriate Gaussian blur for the overall shadow. And then Filter>Blur>Motion Blur. Again, matching the angle of the highlights and shadows. And finally, adding 2% noise to the overall shadow to make it look a little more realistic, then simply click Stop to finish recording.
Now, if I have the same product shots that are consistent for light and shadow, I don't have to do anything else. I can batch automate all of them at the same time after I've created the initial shadows. However, when I'm faced with a different format for a shadow, in this case, my shadow's going in the opposite direction that my jewelry was, I may need to make a change as the action's running. This change is called a modal control and in this case, I want to stop the action at Motion Blur and change the angle that the blur's happening.
To add a modal control, simply click the grey box to the left of Motion Blur, and that will give me a modal control. Now, on my Shadow Smart object, I'll choose my Shadow action, and hit Play. It will run until it gets to motion blur, then pause. Now I can go through and find my shadow. And change the angle and distance of that shadow and then hit OK, and there's my new shadow. It's added 2% noise, a Gaussian blur, and a new motion blur to accentuate the shadow.
