Reels have seven images. At first glance it may seem that our Retro-View (View-Master compatible) reels have many more than seven images but remember that the viewers are binocular and each eye requires its own image to create the 3D illusion. Hence the 14 image windows.
However, almost all of the reels we supply are created from 2D images, therefore the image is simply printed twice – one for the left eye, one for the right. No 3D illusion, but 2D images look fab anyway.
In fact View-Master reels have always had seven images, since the system was created in the 1930s. And people do ask, but it is impossible to have more than seven images on a reel. Seven images and only seven images – that’s the rule.
