This is a PhotoShop CS5 Toolbar Video with Quiz
It is a 13 minute video that contains 4 quiz questions embedded in the video. This allows you to make sure the students watch the video if you assign it to them independently. You can also use it for a class discussion to show the entire class how to use the basic tools of Photoshop CS5.
It goes over the names of all the tools in the toolbar.
The video also demonstrates how to use some of the tools including the following:
Magic Wand Tool
Magic Eraser Tool
I also cover basic keyboard shortcuts:
Zoom Ctrl+Alt+ Mouse Roller
Shift to combine selections
