Kissing Fish
Animation
3.) Click on Alpha 1 in the channels palette to select it. 4.) Go to Image > Adjust > Levels.
5.) Move the sliders in the levels dialog until the outer edges of the coral become mostly white and the surrounding area is mostly black.
10.) Go to Layer > New > Layer via Copy. The coral will appear on a new layer in the layers palette.
12.) It will be place into a new layer above all the other layers. Since we want to have this fish peeking out from behind the coral, we need to move it down one layer. Click on the layer and drag it down between the background and the coral as shown in the animated screen shot below.
14.) Flip, rotate, and move the fish into place behind the coral. If you're not familiar with working in transform mode, see my tutorial on layer transformations. Once you've positioned the red fish, double click inside the transform box to apply the transformation.
At this point, we need to save our file so we can switch to ImageReady to complete the animation.

We'll be using Photoshop and
ImageReady to create the animation shown to the right. This
tutorial uses Photoshop's layers, channels, and transform
functions. The ImageReady portion shows you how to use layers
and tweening to create an animation.
1.) Open the two images in
Photoshop. The two images we'll be working with are shown
here. The red fish has already had the background removed.
2.) Select the background
image and go to the channels palette. If your channels palette
is not visible, go to Window > Show Channels. Look at each
of the channels and choose the one that has the most contrast
between the coral and the surrounding area. In this case, it's
the green channel. Drag the green channel to the new channel
icon in the channel palette (see below).
6.) Select the paintbrush tool
and use black to paint out the non-coral white areas in the
Alpha 1 channel as shown in the image to the right.
9.) After loading the selection, you'll
see a marquee surrounding the selected area in your
image.
11.) Select the 
move tool. Click on the redfish.psd image
and drag and drop it onto the background image. 
13.) Use the keyboard shortcut Ctrl-T to
transform the layer. (Mac users use Command-T)
After saving your file, click the
last button on the Photoshop toolbar to launch ImageReady.
