When you click OK to exit out of the first Displace filter dialog box, Photoshop pops up a second dialog box, this time asking you which file you want to use as the displacement map. Navigate to where you saved the displacement map file on your computer and select it:

Click Open to exit out of the dialog box and have Photoshop apply your displacement map to the shadows, which now bend and wrap much more realistically around the woman:

Step 19: Lower The Opacity Of The Shadows

The only problem remaining with the shadows is that they're too strong. In fact, they're completely blocking the woman from view. All we need to do to fix that is lower the opacity of "Layer 1". Go up to the Opacity option in the top right corner of the Layers palette and lower the value to around 40%:

With the opacity lowered, the shadows look much more natural:

Step 20: Add A "Color Balance" Adjustment Layer

And with that, we've successfully created our window blind shadows! To finish off the effect, let's add some warm sunlight to the image, as if the morning sun is shining through the window. Click on the New Adjustment Layer icon at the bottom of the Layers palette and select Color Balance from the list of adjustment layers that appears:

The Color Balance adjustment allows us to adjust the colors in the shadows, midtones and highlights of the image. It's divided into two main sections - the Color Balance section on top which is where we adjust the colors, and the Tone Balance section on the bottom which is where we switch between the shadows, midtones and highlights. Start by selecting the Shadows option at the bottom of the dialog box, then drag the bottom slider in the Color Balance section above it towards the left to add more yellow to the shadows in the image. Once you've added some yellow, drag the top slider towards the right to add a bit of red as well:

When you're done with the shadows, select Midtones at the bottom of the dialog box and again drag the bottom and top sliders to add yellow and a bit of red to the midtones of the image. Then select Highlights and add yellow and some red to the highlights. Click OK when you're done to exit out of the dialog box.

If you need to fine-tune the amount of color you've added to the image, simply lower the opacity value of the Color Balance adjustment layer in the Layers palette just as we did a moment ago when we lowered the opacity of the shadows layer.

And with that, you're done! Here, after adding some warm sunlight with the Color Balance adjustment layer, is my final result:

And there we have it!
