A lesson on how to resize a digital photograph using Preview software by Apple for Macintosh computers.
Preview is a free program that is installed with the macOS operating system on all Macintosh computers. The primary purpose of the program, as the name suggests, is to allow people to view a wide variety of different image file types. The program has some photo editing capabilities including the ability to resize digital photos.
The following are screenshot images I captured of my computer screen as I worked through the process of resizing a digital photograph.
The first step is to start up the Preview application and open a file that contains a photograph. There are many different ways you can accomplish this task.
You may find the Preview.app icon in the Dock at the bottom or side of your screen. You should find the Preview.app among all your application icons displayed by the Launchpad. Alternatively you can look for the Preview program in the Applications folder on your hard disk.
