Bubble hunters 3D

nobody@flickr.com (Dan (aka firrs)) — Tue, 12 Aug 2008 05:56:47 -0700

Strangers stop to play together with soap bubbles on the Royal Mile, Edinburgh, on Festival Sunday.

This is an anaglyph stereoscopic video. You need to wear red-cyan glasses to view in 3D. Free 3D glasses to Scottish addresses here:
www.cte.napier.ac.uk/firrs/dvd.php

This was invited to be shown in the 3D theatre session of the 2009 Stereoscopic Displays and Applications conference in California

You can see a larger cross-view version on vimeo and small cross-view version here on flickr

(The whole video was recorded at 300 frames per second on a twin camera set-up. The speed was adjusted afterwards).

An experimental timelapse anaglyph video made with the view out of my office window today. You need to wear red-cyan anaglyph glasses to view in 3D. The stereo effect could perhaps be stronger but stereobase was limited by the logistics (and I kinda like my anaglyphs on the weaker side anyway)

There is no audio but I suggest you dial up a bit of Philip Glass or Simone White on the internet.

There has to be a better workflow than this:

Recorded with two Lumix FX12 compact still cameras.
Into Adobe Premier Pro to compile the timelapse (50x speed), deinterlace and turn into balanced red-blue anaglyph
Adobe Premier doesn't do red cyan and doesn't appear to let you properly align the images so export to 2Gb Mov file (yeah 2Gb for 90 seconds!) into StereoMovie Maker to align the left and right images properly. At this point the green channel was copied from the existing blue channel.
Set in and out points, verify sync, align and save to uncompressed AVI.
Into Adobe Premier again to strip out the white noise on the audio (maybe I'm missing an option to not export audio from SMM) and resize to Flickr's 500 width. Apply an equalise filter and export to MPEG2 with a bitrate of about 1.25Mb/sec. Load to Flickr.

I consider this to be a long photo rather than a video - the techniques and composition were essentially the same as they would be for a standard still photograph. In essence this is just a very long exposure that has been time mapped. I have decided to call this technique "High Chronological Range" :-)

Camera: Twinned Panasonic Lumix DMC-FX12

A timelapse test using the view from my office window today - from Merchiston facing North out to Fife (although you can't really see it here). Here an hour and a quarter passes in 90ish seconds.

There is no audio but I suggest you dial up a bit of Philip Glass or Simone White on the internet.

Leith timelapse 3D

From the Crags, Holyrood Park looking north toward Leith and the Firth of Forth.

This is cross-view stereopair. To view this image in 3D you need to cross your eyes until you see three fuzzy images. Then try and focus the middle image. This takes a lot of patience to get right, but once you've done it once it gets easier. Non-3D version here: www.flickr.com/photos/firrs/4931997924/

Two Nikon D80 cameras. Each taking one shot every 11 seconds. Played back at 15 frames per second. Best viewed in HD...even then, unfortunately, Flickr's compression destroys much of the detail. There is a better quality version on Vimeo: vimeo.com/14477867

As featured at the 2007 Royal Society Summer Science Exhibition (www.summerscience.org.uk)

The wood produced from sustainably managed forests in countries like the United Kingdom is increasingly being used by the construction industry - particularly for building new houses. Before it can be used by builders, engineers and architects it must be graded to check that it is strong and stiff enough for the intended use.

Recently developed technologies allow wood properties to be quickly and reliably measured in a non-destructive manner using sound waves and vibration. This can be done after processing at the sawmill, but there are even greater advantages in using it to measure the properties of logs and trees in the forest - allowing the wood to be sent for processing into the best kind of product and reducing wastage of both timber and energy.

There are two main ways of using sound waves (acoustics) to assess wood properties, the "time of flight" method and the "resonance" method. This video shows a demonstration of a resonance method. The tool shown is Fibre-Gen's Director HM200 or "Hitman".
