Abstract:
Traditionally, making a 3D lenticular print requires taking multiple pictures of the same scene along a straight line. The pictures are then interlaced together to create a lenticular print. However, obtaining the source images this way requires very careful planning ahead of time and it is not always feasible due to various environmental limitations and time constraints. Hence, converting a 2D picture into a 3D image easily has been the interest of the lenticular printing industry for years.

Before Photoshop CS4 Extended, converting a 2D image to a 3D image required ad hoc software. Since CS4 Extended, 2D to 3D image conversion became possible within the integrated environment of Photoshop. To the lenticular printing enthusiast, this is a quantum leap. Nevertheless, it is still not intuitive enough to the novice. Beginners still need to do many trial and error runs in order to gain the experience.

In this paper, the author will explain the theory on how to convert a flat 2D picture into a 3D picture by using only the basic functions of pre-CS4 Extended Photoshop in a systematic manner. By understanding the theory behind the conversion you will become confident in creating successful lenticular prints; whether you are using ad hoc software or Photoshop CS4 Extended. Users of pre-CS4 Extended and other graphics editing software such as Gimp or PhotoImpact will also benefit from this tutorial.

Principle of lenticular printing
Lenticular printing is a technology in which a lenticular sheet is used to let different images be seen by the left and right eyes so that the illusion of depth becomes possible on a 2D image. The theory is simple and it is based on the principle of binocular disparity. To understand this, one can do a simple experiment by looking at an object using the left and the right eye separately. You will find that the relative position of an object seen from the left and the right eye is slightly different. By emulating this binocular disparity using a lenticular sheet, one can see an illusive3D effect come alive.
