Say What??? :-0
Let's see if you were paying attention during class or if you were sleeping in the back of the room. :^)
Pam just showed you all the ins and outs of using channel masks in her tutorial here:

This is a fun exercise to see how channel masks and layer modes work. When you are done playing around with this, you will have something cool to print and frame.

This is an .eps vector file. It can be opened at any size, even 40" X 40" X 300 ppi, if you want.
Open this file in photoshop. Make the size 8" X 8" X 300 ppi RGB (if you want to print this later, otherwise 1,000 X 1,000 pixels is a good size to work with)
This is what it looks like (do not download this image).
Getting started:
Open an image you want to work with.
Copy/Paste the image into the first file.
You will have the Black & White Design on the Background Layer with your image on top.
Duplicate your image layer.
Click on the mask icon.
Click on the Design layer.
Select All / Copy.
Now go to the Channel Mask in Channels, then paste the design into the mask box.
Now the design is your mask on the image on the top layer.
Set the top layer to Multiply to see that the mask is working. Part of the image should be dark with the rest normal.
You can change the levels, add texture or blur to make a glass mat effect.
You can inverse the mask to allow the opposite to come thru.
You can duplicate the design on the background layer and use the magic wand to delete portions of it and create a new mask to use for other layers.
You can use the design just as black or colored line graphics.
Use magic wand to make selection, then delete to transparent-deselect contiguous to select all black or all white with one click to delete.
Use the Quick Mask (Q) to edit selections of the design, add and subtract using the white and black brush.
Use hue/sat to change black to a color, using colorize.
Use the design as white on transparent, apply a layer style to make drop shadows.
You can then change the fill to 0% to make the white transparent and the drop shadow will still be there.
You could bring in many different pictures and use the design to mask different parts of each image. Mix B/W with Color. Have the center of the circle be in color, and the rest of the image in B/W with the graphics between as white.
Use magic wand with shift to add selections, option to subtract selections, inverse the image or inverse selection to delete or to fill with a new color. Once you know how to do all this to the design then you will know how to alter, add or subtract masks.
Use layer modes with masks for more special effects. Try Hard mix, Difference and Exclusion for wild effects.
Here is mine:
Give it a try, if you get stuck ask how to get from point A to B. Someone will jump in to get you going. Let's make this like a workshop. Try something new, just play around until something looks good, but write down your steps so you can do it again. Post something here and mention if there was something new you learned from playing with this. This design can be used a million different ways. Practice with it.
This should be interesting...
Have fun!
