Backgrounds, borders & gaps

Press B or click the background button, then drop a photo to the background.

Bring the opacity down so the background hints at the image rather than competing with the photos on top of it. That also lets your background color show through.

Apply the background to just the spread you're on, or to all of them at once for a consistent look through the book.

Set the color behind your photos for the whole project. It shows through a low-opacity background image too.

Turn project image borders on and set the color. There's also a per-photo border if you only want it on one image.

Image gap controls the space between photos on a spread. Zero puts them edge to edge; dial it up to evenly space the gap between image placeholders.

Kills the image gap where the two pages meet - what you may want on a full-bleed spread so there's no gap down at the middle of the spread at the book gutter.

Right-click an empty placeholder and choose Fill with color for a solid or gradient block - what you may want behind text, or behind a graphic like a transparent PNG.

Every color picker in the app has an eyedropper - sample any color from anything on your screen for image borders, backgrounds, text and the rest.

A view-only toggle - it hides the gutter marker on canvas without changing anything about the design or the export.
