On previous pages, I discussed how iPhoto prevents uneven borders by enlarging a photo until it fills the paper size you’ve chosen. And I described how you can use print settings view to zoom and pan a photo to crop it as you see fit.
But what if you don’t want any cropping at all? Easy. In print settings view, Control-click a photo and, from the shortcut menu, choose Fit Photo to Frame Size.
Your print will almost certainly have some uneven borders, but it will contain every precious pixel of your original image. You can trim the borders by hand after printing.
