Photohop 3d Shadow Tutorial

Perspective cast shadow effect

The shadow we are about to produce is going to be a bit harder near the object but gets softer as it moves away.
1. Lasso or Magic Wand an object that will cast shadow. If you need to invert selection use ctrl-shift-i.

2. Make a new layer. Change the foreground colour to black (press the letter d) and fill your selection with gradient, make sure that your currently selected gradient is Foreground to Transparent.

3. Press Ctrl-T to bring up the Free Transformation function. Right-click inside the bounding box and a pop up list of possible transformations will appear. Choose Skew or Distort from this list. You need to make the shadow shape lie almost flat on the ground. Grab the top adjustment points and drag it downward.

4. In the Layers palette drag the layer containing the shadow below the layer with your object. This puts the shadow behind your object.

6. Go under the Filter menu, under Blur, and choose Gaussian Blur. Enter 2 for the blur radius.

7. To add more realism, you can create a perspective blur, where the shadow is less blurry near the object and becomes softer the further away it gets. To do this, use the Rectangular Maquee selection tool to draw a rectangle that covers the top one quarter of your cast shadow. Add a 5 pixel feather to soften the transition. Then go under the Filter menu, under Blur, and choose Gaussian Blur. Add a 2 pixel Blur. Deselect (ctrl-d).

8. With the Marquee selection tool, draw a selection that covers the top half of your cast shadow. Apply another 3 pixel Gaussian Blur, then deselect. Draw a new marquee tool selection that covers three-quarters of your shadow and apply another Gaussian Blur to finish the effect.
