Editing photos on canvas

Drag the lower part of a photo to move it inside its placeholder, and use the zoom slider to scale it.

Right-click any image and choose Flip Horizontal. It works across a multi-selection, and the flip stays with the photo through template swaps and moves to a different spread.

Click the rotate button and drag. Rotation is freeform, so you can level a horizon by eye - hold Shift to snap to clean 15° increments, or Option for fine control when a degree or two is all you need. *The tutorial clip shows the older behavior, where snapping was the default and Shift gave the fine control that now lives on Option.

One button puts a photo back exactly how it landed, undoing any zoom, pan and rotation you have applied to it.

There's a basic exposure slider on the canvas for a quick lift or pull.

Convert one photo without touching the rest of the spread, from the controls on the photo itself.

Select a placed image or a color-filled placeholder and drag the corner pin. It works across a multi-selection, and image borders follow the curve.

Hold Option while you rotate an image on canvas and the drag slows right down, so a one or two degree correction is easy to land.

Settings has a project corner radius that applies to every photo and color-filled placeholder in the book, so you set it once instead of per image. Any corner you rounded individually keeps its own radius and ignores the project setting.

Settings can clear all individual corner rounding in one go, which drops every image and color fill back onto the project corner radius.

Right-click a photo on the canvas or in the library and choose Edit in Photoshop. Save in Photoshop and the edit comes straight back into BookProofs.

The app finds Photoshop on its own in most cases. If it doesn't, or you use something else, set the application path in settings. Results with other applications vary - some work, some don't - so if there's one you want integrated and it isn't working, let us know and we'll take a look.

Cover fit is the default placement inside placeholders for BookProofs template design: the photo fills the placeholder. Contain fits the whole photo inside the placeholder instead, so nothing is cropped no matter what aspect ratio placeholder the image sits inside. Turn on the contain/cover toggle in settings if you want that choice per photo. It's highly recommended to leave Reset to cover on template change switched on: with it off, contained photos keep their fit when you change templates and the layout will almost certainly provide unexpected results on template swaps.

Finds faces so an off-ratio crop lands better on the subject. It's around 85% accurate and adds time to import, so it's currently turned off by default.
