Hi Stephen,
Sorry for the delayed response - I'm in Japan & I think our timezones
are a bit off... I wonder if you've already tested your 3d optics setup
with SpyKids?
Anyways, sorry to dissapoint, but I don't think it'll work the way you
planned. As far as I understand 3d video, they shoot it with two cameras,
and then it appears on-screen as two distinct images, one tinted red, and
one tinted blue, each a little offset horizontally from the other. If you
look at the screen through the red lens, one image will be clear and the
other will effectively become invisible, and vice-versa with blue. If we
wear blue on one eye, and red on the other, each eye will see a different
image, and as 3d is filmed with two offset cameras, this tricks our brain
into recieving all of the binocular cues to depth.
So, in short, I think you'll need the glasses.
Enjoy the movie!

Subject: red/blue 3-d imagery (light question, not photography)

> I recently rented the DVD video for Spy Kids 3D. It uses the traditional
red/blue imagery for the 3-d effect. The rental shop doesn't include the
red/blue glasses with the rental, which would be included if I were to
purchase the DVD. I don't want to dig through the boxes in my garage to find
my Lee Filters sample pack. I have red and blue flashlights, from
Streamlight <http://www.streamlight.com/stylus_specifications.htm>, readily
available. Do you think I will be able to enjoy the 3-d effect if, instead
of viewing through red/blue filters, I project red/blue light onto the
viewing screen? I am goint to test it this evening, but I wanted to get some
knowledgeable hypotheses from the forum regrading the viability of this
idea.
