$blueprint = new Kirby\Cms\PageBlueprint(array_merge(['model' => $page], Kirby\Cms\Blueprint::load('pages/album')));
dump($blueprint->section('images'));
While this seems to work, I guess the idea here is to actually pass the page object that belongs to the blueprint, but then you might as well call the blueprint() method on the actual page (but querying the complete site()->index() just to get a value from a blueprint seems to be overkill.
