Introduction

The purpose of the 3D Stereo Magic, How to Make Stereo Power Windows tutorial is to provide techniques every digital stereographer can use to create image enhancing, eye-popping, jaw-dropping window and stereo effects that make you say,

        “How’d they do that?”

On a more practical note, special frames can often be used to eliminate window violations in images which otherwise cannot be saved. A very important application applies in the creation of anaglyph images where certain frames can be used to drastically reduce ghosting in many images while, simultaneously, preventing window violations.

Any reasonably full featured image editing software, such as Photoshop, Corel’s Paint shop Pro, Gimp (a freeware), and others can be used to create the effects described.

All procedures are described for Adobe Photoshop CS3, but are known to work in all previous versions down to version 6. Even Photoshop Elements will work. If the process is different in a previous version, that is noted. This is not an instruction manual for the operation of any software, although step-by-step procedures are provided for specific applications when appropriate, particularly for Adobe Photoshop. A level of competency in stereo photography and digital stereo alignment is assumed, so firm understanding of basic concepts is assumed.

My sincere thanks to those who first explored frame manipulation, prominent among them is Hubert Becker. Then, I offer thanks to those who personally guided me over rough spots in learning to use Photoshop and gave me inspiration with their own skills with Photoshop and in the art of image and stereo frame manipulation, John Davis and Mike Ihde. Finally, thank you to Peter Blyth, who pushed me to compile my one-on-one training sessions into books and make them available to the entire stereo community.

Wishing to share that knowledge and pass the torch, so-to-speak, to others, it is my sincere hope that the information presented here will give you the renewed interest in stereo photography that it gave to me. If any single concept found here excites you and finds its way into your art, then I am well compensated.

Good luck,


Conventions Followed in This Tutorial

A.  Figures in the tutorial appear in parallel view. For those who prefer cross-view or anaglyph formats, the figures will be found in those views and in parallel view, all in full color, on the CD. All explanations will work for the creation of stereos for any viewing format preference. While the final steps given are for the production of traditional parallel view stereograms, it is assumed that those who prefer anaglyph can take two perfectly aligned stereo chips and convert them to anaglyph presentation, either in Photoshop or with a dedicated anaglyph program. Those who prefer cross-views can convert the stereogram to that view by simply swapping the chips.

The images on the CD are JPEG, organized into 6 folders; Parallel, Cross-view, Anaglyph, Chapter 10 Figures, Chapter 11 Figures, and Misc. Figures. You can view them with any viewer you choose or with a slide show program.

B.  The images (chips) are named “left” or “right” for the eye which views them. This is important to remember in cross-views where the left eye chip is on the right side.
