Traditional 3D Methods (Passive)

There are many ways to create an image that will fool your brain into thinking a 2 dimensional surface has 3 dimensions.  Years ago, all we had were Red/Blue blocking 3D glasses a lá Match from Back to the Future. This technology involves filming in stereo where the camera has 2 lenses spaced apart to record video just like how your eyes see.  It’s kind of like looking through a periscope on a submarine but instead of bouncing the light down the tube with mirrors, it is bounced through time on film. Your left eye should only see what was recorded by the left lens and your right eye should only see what was recorded by the right lens. Your brain then uses all kinds of fancy geometry to assemble these two images back into one 3D view of the world

Match from Back to the Future

Similar technology is used these days with digital projection where you have polarized lenses where each lens is designed to block/permit light that is polarized in a certain way.    Whatever the left lens blocks is permitted to go through the right lens and vice versa. The easiest way to demo this is if you have a pair of leftover glasses from your last movie theater 3D outing,  put them on, look at yourself in a mirror, and close one eye.  You won’t be able to see your other eye behind the glasses in the reflection because the light that passes through the glasses has been fully blocked, neat huh? When you are in the movie theater, the projector swaps between polarization for the left and right eye something like 120 times a second (as opposed to a normal projector which only needs to flash frames at 29.97 frames per second to prevent flickering as detected by the human eye/brain).

Modern Polarized 3D Glasses

Older polarizing 3D attractions at places like Disneyland use a similar technique, but I have a feeling they use two separate projectors rather than just switching back and forth on one projector.  That’s why sometimes when one projector isn’t as bright as the other you get this really wonky effect where it feels like you can’t see through one eye and you think the glasses are dirty.

Another way to do it is by switching back and forth between two static images taken slightly apart from one another. You can see a bunch of cool examples of this method here. When I was going through the pictures from my recent Disneyland trip, I came across a couple pictures in a row that seemed by a jolly accident to work with this effect.

If you click to embiggen the image, the effect is easier to see.

Photo Tuesday: Disneyland Monorail Blue on a clear day

This picture was taken during my trip for Disneyland’s 55th anniversary weekend. While waiting to get onto the Matterhorn (which took quite a bit to convince my dad that it didn’t flip or have any crazy drops to make him lose his stomach) along came Monorail Blue. It’s amazing how much quieter the Mark VII monorails are than previous models.

B&W and Color Footage

While visiting Disneyland for its 55th Anniversary last weekend, one of the special things they did to commemorate the day was to replace the B&W Mickey and Minnie Cartoons in the Main Street Cinema with Disneyland Opening Day footage.  Some of the footage is black and white and some is in color. There were a few different reels they had playing, and I did my best to grab a few. This is the first reel that I captured.  I added some audio to the silent films and I hope you enjoy these seldom shown recordings.

Disneyland’s 55th Birthday

The Emerald Anniversary

Next week, on July 17th, Disneyland will be celebrating it’s 55th Birthday.  Today, the Disney Parks blog announced the schedule of events for commemorating Disneyland’s anniversary including a dedication ceremony at noon, a birthday sing along at 4:15, special Retro-designed park maps,  and a special set of Mickey Ears available only on July 17th that reads: “D 55th,” July 17, 2010.  I was there last year for the 54th Anniversary and I recorded a somewhat shaky video of the commemorative ceremony with The Mayor of Mainstreet, the Disneyland Band and Mickey and Minnie Mouse.

As you can see, the festivities were rather simple, but special none-the-less.  It seems like they do a bigger deal when the anniversary mod 5 = 0. 🙂  Or, in non-engineer speak, anniversaries that end with a 5 or a 0.  During the 50th Anniversary, they celebrating for 2 years and we ended up with the wonderful fireworks show called Remember… Dreams Come True as narrated by Julie Andrews.  I absolutely adore Julie Andrews — for me, listening to her speak is like a warm voice-hug. The 50th anniversary also brought us the Walt Disney’s Parade of Dreams once again, narrated by Julie Andrews. Both of these  were strongly imbued with Walt’s touch when they chose to include audio recordings from his Original Dedication of Disneyland Speech.  If there ever was a time you could feel Walt’s presence up above the Firehouse, it’s listening to Walt’s Dedication on the Park’s anniversary.  And the Park never looked so beautiful as when it was all decked out with Mickey 50’s.

May you always stay young at heart. And may your Dreams continue to be inspired by imagination. And may you forever treasure this very special day at the Happiest Place on Earth.
