1: Select photos
First, select the photos you want to print. Drag a box around them or hold the Cmd button as you click in individual shots to select multiple files.
Open the File menu and scroll to the Print option. You also have the option to order prints from Apple in the same menu – they’ll be posted to you.
The Print menu offers a small number of basic presets for you to try. The small preview on the right gives an idea of what your printed shot will look like.
The options at the bottom offer different sizes, both for the paper you are using to print on and the size of the prints themselves.
Hit the Customise button and you can access a selection of extra options to let you personalise your prints with themes, backgrounds and borders.
6: Pages and photos
At the top you can see the pages and photos in your printing set. You can add multiple photos to a page by changing the image dimensions.
7: Edit mask
Click the image and you will see options to edit how much of the photo you print. You can drag the slider and use the hand icon to change things.
8: Backgrounds and borders
Use the controls in the bottom-right to edit the background of your page, as well as add borders to your image. The latter will cut off some of your shot.
When you are ready to print, you can do so with a single click on the Print button, or access more intricate settings by hitting Print Settings.
