Image Shadow

Found the perfect image… Check.
Great shadow… Check.
This image is going to be so awesome sliding into my course.
Opening up file… Oh, the image is flat, no alpha channel… Uncheck?

I could create a selection around the object and call it good, but I really liked the image shadow and don’t want to recreate it.

Have you ever been upset because you’re in a similar situation?

For this tutorial I made a cutout of this adorable pit bull:

Here are two ways to Save Our Shadows.

First step is the same in both. Duplicate the base layer. Create a selection of the object in the image you wish to save, create a mask. You should have the object isolated, without shadow.

Then go to the duplicated layer you want to take the shadow from.

Channels

This is the way I learned.

  1. Select the layer you want to take the image shadow from and go to Select>All and press Ctrl+C.
  2. Open the Channel Pallet and create a new channel. Press Ctrl+V to paste the image in this channel.
  3. No deselect. Then press Ctrl and select the new Channel you created. Reselect the RGB channel.
  4. Go back to the Layers Pallet. Go to Layer>New Fill Layer>Solid Color. Rename it and press OK.
  5. Change the color to black and press OK.
  6. Now select the mask and select all. Go to Image>Adjustments>Invert to grab the shadows.
  7. Place this layer behind your cutout image.
  8. Save as a PNG.

Luminosity Channel

This way is much easier and less confusing.

  1. Select the layer you want to grab the shadow from and press Ctrl+Alt+2.
  2. We have the highlight selected, so, press Ctrl+Shift+I (or go to Select > Inverse).
  3. Go to Layer>New Fill Layer>Solid Color. Rename it and press OK.
  4. Change the color to black and press OK.
  5. Place this layer behind your cutout image.
  6. Save as a PNG.
