How to Fade One Image Into Another
*in progress*
Again, done in Photoshop CS3....I don't know about 5, but I know Elements 4.0 can't do this the way I'm explaining it.
Follow this link to the images I used for this tutorial - Open two images, preferably the same height
- Press Ctrl + A to select all of one image (in this case, the bridge image), press Ctrl + C to copy it, and paste it onto the other image (in this case the blue zone) by pressing Ctrl + V
- Position the top image so that it’s left side is at about 25% on the other image (0% being left, 100% being right)
- Now, make sure the bridge image is the layer selected, and click Layer >> Layer Mask >> Reveal All
The image won't look any different; however, the Layers palette should look like this:

- Now, click on the Gradient button, and make sure it is set to horizontal gradient with white on the left and black on the right

- Making sure the bridge layer is still selected, place the cursor at 50% horizontally, and drag the gradient to about 25% horizontally (0% being left, and 100% being the right side of the image)
Your image should look somewhat like this:
And here's an example of how to put this process into use in a signature:
The End!
