Many readers are still emailing me about Nikon’s new NF-300i 3D photo frame. I guess my previous post was mainly targeted at the new Picturetown 3D service, even though the new 3D photo frame is part of this service and was mentioned in my post. Here are some more details on the Nikon NF-300i photo frame.
Nikon was able to achieve 3D images without the use of special glasses by arranging separate images for the left and right eyes. The actual implementation was done with the help of lenticular lenses (“designed so that when viewed from slightly different angles, different images are magnified”):
On the figure above, the right eye will see the blue portion of the image, while the left eye will see the red portion of the image. Because of the different angles the left and the right eyes view the separate images on the frame, the combined picture can be perceived as 3D.
