Shapes:
To change a photo's shape, use Masks or Frames from the left-hand menu. Just drag and drop a mask or frame (like a circle, heart, or custom cutout) onto your photo.
Filters:
Filters can be a great way to add a creative flair to your photo book project in just a couple of clicks.
You can apply filters (like sepia, black and white, or negative) by right-clicking your photo and selecting Edit > Effects.
In this video we teach you how to edit filters on your images in the online editor.
