Step 2: Choose one image to select and go to the Select Menu Select All.
Step 3: Edit Menu Copy.
Step 4: Activate the destination document (or the second image) by clicking
on the image.
Step 5: Edit Menu Paste. The i rst image should appear in the Layers palette
completely covering the image below.
Step 6: Scroll through the dif erent blend modes in the Layers palette to i nd
one that works with the images. Keep in mind that many blend modes may
not produce pleasing ef ects at all. The blend mode Darken worked best for
my images.
Step 7: Experiment with reducing the opacity of
the image in the top layer.
Step 8: Combine this technique with other techniques. I added color.
