This well-produced video by Mark Gambier offers a clear, concise explanation of the history and science behind Stereo Photography. It doesn't get easier to understand than this!

(This is actually the first part of a longer video. Though as Mark notes in the comments, it was produced in 2006, so the section on Photo Equipment doesn't include the latest advances in digital camera technology.)

More big movie news, this time from THR's Heat Vision blog:

Warners has been testing footage from its upcoming "Clash of the Titans" -- converted into 3D by an outside vendor -- and the tests have gone so well that execs have decided to release not only "Titans" but also the two-part "Harry Potter and the Deathly Hallows" in 3D.

3D conversion expenses are said to be around $5 million for each film, which they expect to easily make back at the box office.

"Titans" opens April 2, followed by "Deathly Hallows: Part 1" on Nov 19. "Part 2" is set for July 15, 2011.

From Variety:

Zaslav said he was sold on 3D TV after attending the Consumer Electronics Show this month in Vegas, where it was clear that TV set manufacturers "are getting behind this (technology) in a very big way."

The three partners plan to produce enough 3D programming to fill a 24/7 channel. Discovery is also looking at "upconverting" some of the shows in its vast library to 3D, just as the majors are doing with classic pic titles.

Sounds great. If you haven't noticed from previous posts, I'm a strong believer in 3D conversion tech. Discovery has a huge catalog of programming that would be amazing in 3D (and without digging into the catalog they may have trouble filling a 24/7 channel with 3D programming).

Street fairs, expos, sporting events, parks... If you can find a crowd, you can find a great shot. People are usually doing something interesting, even when they aren't.

The main challenge with shooting crowds of strangers with a stereo camera rig is... well, the rig itself.

I've found it's almost impossible to use my rig in public without attracting attention, so instead of avoiding these inevitable conversations, I use it as an opportunity to educate curious onlookers about stereography. (I'll pass out my photo URLs and paper glasses, if I have some handy.)

An organizational note: Almost all of my Photo Sets will have a few people in them. This set is for stray "people shots" that don't belong to a specific location or event.
