Learn to blur out the background of an image using the radial blur & zoom filter in Adobe Photoshop. This will assist students to avoid noise in the background that is unwanted in any image. Its a great resource to assist in making images for classroom projects and reports. It is a fast and easy lesson, and I usually require 10 versions of the radial blurs in a specific folder with file names to check for file management/organization. Thank you. Respectfully, Mr. Riese
