Layer Masks in Elements

Using a Pattern Adjustment Layer to Blend Two Images Together

  1. Have 2 images that you want to blend together into a single photo. They must be the same size, same pixel dimensions.
  2. In the SIG I used lion 1 and lion 2
  3. Add a Levels Adjustment Layer on Lion 1. Notice Adjustment layers have a Mask. Make a levels adjustment and click OK. If you make any adjustment with Levels you can paint with black to hide the adjustment or white to show the adjustment. Flatten to apply your adjustment.
  4. Select your other image, in my case Lion 2.jpg
  5. Select > All or the shortcut Ctrl+A
  6. Edit menu > Define Pattern
  7. In the first image, in my case Lion 1.jpg, add a Pattern Adjustment Layer. The last created pattern, Lion 2, will appear as the current pattern to be applied.
  8. With Black as the Foreground color and white as the background Select the Gradient tool and drag on the Mask to blend the two images together. Start the drag where you want to stop hiding what is on this layer and stop when you want the layer fully revealed.

Layer Mask using an Adjustment Layer as a Clipping Group.

I used two images, one with a bald sky, Space Adventure and another with the sky I wanted to use to replace the bald sky, clouds.psd. The following are the steps taken to replace the bald sky.

  1. Open Space Adventure.jpg
  2. I used the Magnetic Lasso to select the foreground. You can use whatever selection tool that gives you the selection that fits your subject. You want the sky to be eventually selected. I selected the foregroud because it suited the Magnetic Lasso tool.
  3. I added the trees with the Magic Wand with the Add button selected on the Options bar.
  4. In the Select Menu click Add Similar to get trees that weren't selected.
  5. Select Menu > Refine Edge to adjust the selection.
  6. In the Select menu > Inverse to now make the sky selected
  7. Select > Save selection.
  8. Double click the Background to change the Background to a Layer
  9. Open clouds and move with the Move tool to the space adventure image
  10. Drag the clouds under the space adventure layer.
  11. On Space layer add a Levels (could be any) Adjustment Layer
  12. Drag the Adjustment Layer under the Space layer
  13. With the Space layer active select Group with Previous to create a clipping group with the Adjustment Layer.
  14. Click on Mask in the Adjustment layer and in the Select Menu load the sky selection.
  15. The new sky should now replace the bald sky. If the sky replaced the foreground instead, click on the Mask and Ctrl+I key to Invert the selection.
  16. You can paint on the mask with black or white to touch up your mask.
    8. Load selection in Mask
