This course primarily focuses on the Standard Edit mode of Photoshop Elements, since everything you can do in Quick Fix, can also be done in Standard Edit, and the standard edit mode more closely resembles working in the professional version of Photoshop. Quick fix is useful for simple image adjustments and one-click tough-ups that don't require the use of selections and layers. It's fairly straightforward and is designed primarily for working with the auto-adjustment tools. Feel free to explore the Quick Fix editing mode on your own.
If you've worked with Photoshop Elements Organizer, you may have noticed that the Organizer offers commands for opening a photo directly into Standard Edit or Quick Fix. When you do open a photo from the organizer into either one of the editing modes of Photoshop Elements, the Photo Organizer will display that photo with a lock and red bar across its thumbnail. This is nothing to be concerned with; it just means that the file is in use in another program, and it blocks you from working with the same image in the editor and the organizer at the same time. This protection is necessary since it could trigger a conflict if two programs try to write to the same file. The lock and red bar will go away as soon as the photo is closed from the Editor.
