Materials / resources
A high-contrast image file for selection practice
Location for students to upload files for grading
Students will need a high contrast image with which to practice making selection.
Present the slideshow on Making Selections in Photoshop. It may be most useful to use the presentation as a guide while the teacher performs each selection process.
As students try each method of selection, have them copy (command C), create a new Photoshop document (command N) and paste (command V) the section into a new Photoshop document. Save each of these with their name, an underscore and the name of the method used. For example, “JoeSmith_Magic Wand.jpg” or some other naming convention of your choosing. As each portion is selected and copied, the new Photoshop document will automatically be set for the proper size.
Proceed through each of the selection methods. Students should end up with FIVE demonstrations of selecting: Magic Wand, Magnetic Lasso, Refine Edges, Quick Mask mode and a fifth which will be their best effort demonstrating their best selection effort.
Upper level students should be able to combine this lesson on selections with the Adjustment Layer lesson to select and make color correction adjustments to only desired portions of an image.
Lower level students should practice and become proficient in one or two selection methods.
