Have you wondered: about how to view stereo images?

PSA Journal , Nov, 2003 by Jean Timmermeister

The September issue of the Journal featured the beautiful stereo images of Past President Dr. Albert Sieg, Hon. PSA, FPSA, EPSA as one of the Society`s Distinctive Image series. Unfortunately, viewing 3-D (stereo) is not a talent of many people, or even of all photographers, so this month`s Have you Wondered will try to help PSA members learn how to `see` stereo images. Dr. Sieg has said, "the fact is that 98% of the PSA people that see the images will not have a clue that anything is wrong " when stereo images are not printed correctly.

But in order to change that percentage, this month we try to offer help. There are various forms of 3-D glasses that can be purchased if the buyer knows where to look, but free viewing is the answer to looking at a stereo image and seeing it in 3-D. Remember that when we are shooting our images, we are seeing in three dimensions, but producing in two dimensions. The stereo photographer, on the other hand, is intent on making a three-dimensional image for a more `real` experience.

George A. Themelis has provided some freeviewing tips of his own, as well as the description by other stereo enthusiasts. I have included three descriptions of how to view without special glasses.

"Parallel Freevision

"Focus across the room. Gradually raise the stereo pair into your line of vision while holding focus as at distance. The left hand image should be in front of your left eye and the right hand image in front of your fight eye. Don`t focus until you notice an additional image in the middle that has formed in your field of vision. This is the 3-D image. Now focus on it."

"With practice, the side by side images can be `freeviewed` in full (and amazing) 3-D. The technique for free viewing is similar to the one used for viewing the Magic Eye posters. You need to have your eyes looking parallel to each other. Stare directly at the pair, letting your eyes relax and defocus, or focus at a distant point. A pair of strong reading glasses will make free viewing much easier."

And "Parallel vs. Cross-viewing

"A . way to freeview is by crossing the eyes. In this case the left image must be placed in the right side and right image in the left side. By crossing the eyes it is possible to freeview the image. There is no limit in image size that can be freeviewed using this method and for this reason it has become popular in computer stereo.

"Some people are able to parallel freeview but unable to cross-eyed freeview and vice versa. With enough patience and exercise most people can do both."

It is Journal policy to publish 3-D images in parallel freeview format. That is the way the 3-D images in this issue are presented.

From preps to Tuscaloosa, Wallace keeps his word - basketball player Gerald Wallace of the University of Alabama

Sporting News, The , June 12, 2000 by Mike DeCourcy

Gerald Wallace never said he would dash directly from high school to the NBA. Not once, at least not in public. From the first time he was asked, he insisted he planned to attend college. Later, he identified the college in question: Alabama.

If anyone believed Wallace, it wasn`t evident on the February night his Childersburg High team played a home game against Huntsville`s Butler High. There were a half-dozen NBA scouts in the gym that evening, most of whom had flown to Birmingham and rented cars for the 55-minute drive.

"Tile NBA people say they don`t really want high school kids coming out, but they hear people thinking about it, and in doing their jobs, they go to watch games," says Crimson Tide coach Mark Gottfried. "You put seven or eight NBA people in the gym, and other people in the gym start thinking the kid`s a bona fide No. 1 pick in the draft

"It`s hard for people to sort out what`s reality. What are the NBA people really doing there?"

When the early-entry list for the NBA draft was released last month, high school players were included--Fresno`s DeShawn Stevenson, Darius Miles of East St. Louis, Ill.--but Wallace`s name was missing.

Nearly a year had passed since Wallace jetted from obscurity with a rim-shaking performance at the Bob Gibbons Tournament of Champions. Wallace was nearly unknown when that club tournament began; before it was over, he had become the nation`s top-ranked recruit, and speculation ran rampant he never would play in college.

Few bothered to wonder what Wallace`s plans were, and few took him at his word when he said his plan was to play for the Crimson Tide.

Wallace seriously considered entering the draft but did so rationally. He watched the number of players with college experience announce their decisions to turn pro, started counting heads and figured his opportunity to be chosen as a lottery pick was dwindling.

"It`s always been one of my goals to make the NBA, and fortunately I had the chance to go out of high school," Wallace says. "I didn`t think I was ready to make that jump, from playing a game I love to playing as a job. I wanted to have more time to relax, have fun and enjoy the game a little more."

As a college prospect, he left no doubt about his ability. He averaged 29 points and 15 rebounds as a senior and received Mr. Basketball honors in Alabama. Wallace (6-7, 215) advances the ball from the wing to the rim as quickly as any small forward/ shooting guard to come along in the past two decades. This is his greatest gift as a player, but he also is a promising shooter and uses his athletic ability to rebound and block shots.

"Every time somebody challenged him, it was like they woke up the sleeping giant," Gottfried says. "He`s got a competitive nature in him that`s just unbelievable. He`s fearless."

Alabama lost wing Schea Cotton to the draft after he averaged 15.5 points in his only season, but Wallace`s arrival will mitigate that loss and make the Tide better. Wallace is more versatile, more efficient, more dynamic and more competitive than Cotton.

With Wallace joining shooting guards Rod Grizzard and Terrance Meade and big men Erwin Dudley, Jeremy Hays and Kenny Walker, Alabama should contend with South Carolina for the honor of most improved in the Southeastern Conference and challenge Arkansas for the SEC West title.

Gottfried thinks that when Wallace gets a taste of college life, he`ll want to stay for more than a year. He doesn`t turn 18 until late next month, and there may be no rush to become a tax-paying adult.

If Wallace does not last at Alabama past the 2000-01 season, he at least does not arrive demanding to play a specific position or a certain role. He is eager to improve himself and his team. There will be lots of NBA scouts watching, but he`s used to it.

"To me, it was just another crowd that wanted to see us perform," Wallace says. "If they saw something they liked, maybe they saw something they didn`t like, too. It never stopped them from coming to the next game."

The candidate moving most quickly to the front of the line to replace Lon Kruger at Illinois is Oregon`s Ernie Kent, who got the Ducks into the NCAA tourney in his third season. In addition to Tulsa`s Bill Self and Vanderbilt`s Kevin Stallings, Illinois also may look at Miami`s Leonard Hamilton and Rob Evans of Arizona State . Illinois assistant Derek Thomas, who previously worked at Saint Louis and Minnesota, is among the candidates for the opening created when Missouri-Kansas City dumped Bob Sundvold. Oklahoma assistant Ray Lopes and UMKC assistant Steve Eck also are contenders . Arizona is taking advantage of a little-used NCAA rule that allows for a "student assistant coach" in order to keep Josh Pastner as part of the program. Pastner was a reserve guard who helped work out teammates and break down film during four seasons with the Wildcats. He also coaches the Houston Hoops club program, which gives Arizona an extra set of eyes on the summer recruiting circuit. SG Dahntay Jones thinks he will pro gress more quickly at Duke than he did in two seasons at Rutgers, and his transfer will give the Blue Devils an experienced replacement for Nate James, who has one year left . The biggest surprise of the Bob Gibbons Tournament of Champions was 6-10, 215-pound C Sani Ibrahim, who has moved from Nigeria to Atlanta and is expected to play this fall for W.D. Mohammed High . New coach Paul Hewitt already is making a positive impact on Georgia Tech`s recruiting. Tech is leading in the pursuit of agile, 6-9 low-post specialist Emeka Okafor of Bellaire High near Houston. Xavier wing recruit Romain Sato, a native of Africa still learning English, got the required SAT score to be NCAA-eligible and should join the Musketeers in the fall . Terence Green, an assistant last season at Eastern Michigan, has joined the Michigan staff. A Flint, Mich., native, he is credited with helping mold the Flint trio of Morris Peterson, Mateen Cleaves and Charlie Bell, who together led Michigan State to the national title.
