Layout
A layout applies recommended borders, shadows and content; you can still fine-tune each setting.
Canvas ratio
The canvas follows the photo and the borders.
Preset code
A preset code stores the layout, canvas ratio, logo, fonts, borders, spacing, shadows and export options, plus which details are shown and their sizes. It never includes the photo, a custom logo image, the caption and tagline text, or the output quality.
