Preview Panes
Under the Finish and Fix Artwork buttons, you will see the Preview Pane with four tab names above the Pane itself - see the screen-grab below:
PC
Mac
The Original tab shows you what your original image looked like when you opened it.
The Adjusted tab shows you what your original image looked like after you adjusted it in the Adjust Editor - if you did nothing to it then it will look the same as the original. The tab called Studio gives you a real-time preview of what the Canvas might look like if the entire Palette was blended with the Canvas, at the given Mixer settings.
The tab called Wizard gives you a preview of what a chosen ArtWizard looks like on a Fo2PiX selected default image. What you see here is only meant to give you an idea, as you can slightly or radically change the way an ArtWizard produces a piece of artwork.
