3D Thursday: Nuit Blanche Ottawa Gatineau #nbog13

I took a number of photos during this year's rainy-but-well-attended Nuit Blanche Ottawa+Gatineau on September 21/22, but only two 3D photos. I no longer have two cameras and it's hard to take a pair of stills with moving people in the shot.

Both of the 3D photos I took were in the Market. This tree was nicely done up on George Street, I think by the O-Town [Yarn-]Bombers:

You can see the two exposures by closing one eye, then the other. I think between exposures, a couple of the lights were turned off in the condo building in the background.

With brightly-coloured things like this, the colour shots don't work quite as well because red objects only appear in one eye and blue objects only appear in the other. Here's the same photo again with the colours removed before converting the layers to red and cyan:

The next one is a photographic sculpture by Susy Oliviera at SAW Gallery, called Have Everything and Die. The wall behind was red, so I didn't even bother trying to do the 3D conversion in colour (but I've left the colour in the source photos below).

This sculpture is ideal for photographing in 3D, because a regular photo doesn't capture the essence of it. It's a bunch of pieces of photo moulded together into a kind of sculpture (she had another, photographed on Peter Simpson's Big Beat blog here), but instead of the face put convex (with the nose pointing out), it's concave (with the cheeks and nose going inward):

That's a pretty important part of the piece that you don't get with a regular photo of the sculpture.

But a really neat thing about the 3D photos is if you flip your 3D glasses around (i.e. the red filter on your right eye instead of your left eye), it looks convex! This is a neat twist on the old paper dragon illusion or the rotating mask illusion.

While I'm talking about Nuit Blanche 2013, I should mention that I happened to be in Toronto this October to see Ai Weiwei's Forever Bicycles sculpture, which was installed outside Toronto City Hall for their Nuit Blanche. The colour-changing lighting scheme prevented me from taking any photos in 3D (since I'd need to take two photos in succession), but it's still really neat:

The description says that it's made up of 3,144 bicycles, and the title is a play on the name of China's largest bicycle brand, Yong Jiu, which translates as "forever".

They're not real bicycles, but rather a steel representation of bicycle frames. But the wheels are real bicycle wheels and they all spin freely!

It's possible I'm just imagining it, but from a distance, it looks like the shape of the sculpture is a pair of giant bicycles heading each other off on Nathan Phillips Square:

Truly mesmerising! A shame I couldn't get this shot in 3D!
