Music is "Für Elise - Rondo" by Qoo.
The exposure is far from perfect. The skies looked quite good in the moonlight, but I failed horribly at getting any of that to look good - perhaps I should go for just the moon + stars next time... | Tom.Lechner posted a video:
This is a moving sculpture I made in 1997 from holly, maple, and mahogany woods. I leave it as an exercise for the viewer to determine exactly what conditions must be satisfied for the tracks to slope downward on either end, and still have the roller roll back and forth.
Irrelevant side note: My computer stopped recognizing firewire, and thus could not read from my camcorder, and I just spent half a day figuring out why, and how to fix it. Namely, the recent Debian Linux kernels do not provide firewire capability the same way they used to by default, and just about every firewire based program I have can only use the old way! So I had to figure out how to recompile my kernel with the old way enabled. BUT the kernel would start to compile, and simply crash, without a decent explanation. Had to track down and remove "xen", which has something to do with "Paravirtualized guest support" whatever the hell that is, and then I finally got firewire again.. I know Linux has come a long way, since I haven't had this sort of irritating problem on my machine in a while. When I started with Linux, this sort of thing happened constantly! |

Demonstration of the current state of my panorama projection software. Unwrap right on screen, then render to an image that can be printed out, cut and folded into a physical shape! In this case the Snub Cube, with Mt. St. Helens on it.
The next step is, of course, defining sides that are curvy. Globe gores, for instance, or rinds. Might be quite a while before that though! As far as coding goes, someday I hope to understand how lighting works in opengl, and how to do texturing efficiently...
Another thing I'd like to do is make controls for panorama reprojection to automate things like this. This would be equivalent to an extension of Hugin's new gl previewer, which lets you change how the panorama is projected in real time, which in itself is a lot of fun to play with. Just need to record a camera orientation path, and render along the path!
notes on video production: try as I might, I simply could not get Kdenlive to render the words at the end without flickering, except in really crappy resolution!! Kdenlive has come a long way in the last few years, but there are still many quirks to iron out. Then flickr wouldn't take the video kdenlive made, but would when converted to a wmv, and only a wmv with mencoder, but not in the proper aspect, without first rerendering in kdenlive to different dimensions.... AAARG!!!
Oh, and the music is me playing around with the arpeggiator on my keyboard. |

I setup the Canon XT on a tripod behind the drivers seat with some bungie cords to hold it in place. With some time lapse software I found online I set the camera to take 30 second long pictures with a 5 second gap between them. We started this just east of Ottawa on the 417 and drove into the fog somewhere east of Quebec City. We were on the way to PEI.
Jeff is driving, and I am keeping him awake in the passenger seat. That is my phone on the dash recording a gps track of our drive, and my foot randomly appearing.
We stopped for gas near the end of this shot.
Encoded with mencoder on Ubuntu: mencoder -nosound mf://*.JPG -mf type=jpg:fps=14 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=8640000 -vf scale=1080:720 -o output03.avi
I copied the encoder settings from the video notes for: www.flickr.com/photos/colink/3695492428/ | colin k posted a video:
Construction site across the street. Mostly they seem to be moving dirt around, although they are filling in holes on the right side of the screen (out of shot, blocked from my window...) Presumably in a few days they'll start digging out for the inevitable condo parking.
Most of video is at 2 seconds per frame, but I switched it to 1 second per frame near the end, so you might notice it gets a bit slower around the 47 second mark.
It was partly cloudy, which is really good for getting cloud shots, but for shots like this the variance in the light levels mean that some of this video is too dark and some is overexposed (since for time lapse the camera needs to be set on fixed manual settings...)

Missed the sunset, this is actually facing east... I like the movement of the moon, but it's not as cool as the cloud movement in #1 or #3.

Time lapse, and a touch of image processing to spruce it up a bit. (The source images were pretty washed out, a consequence of my not-quite-perfect manual settings needed for time-lapse...)

Cool weekend at the cottage, nothing to do but drink, eat, drink, read, drink, and take long timelapse photography experiments....
I like the cloud perspective effect on this one.
Note: Flickr's video player seems kind of weak. The video looks smoother if you pause, wait for it to finish loading, and then restart. When I start doing more than just these little experiments I may have to put them on Vimeo or YouTube or something....

Note:
Phottix Nikos was working fine with 1 or 2 second intervals this time around; previously I had trouble making it work with intervals less than 5 seconds. Not sure what I changed that made it work ok... | auggie tolosa posted a video:

From my fire escape last night. Even with thirty pounds of weight on the tripod post it still got blown about!

That took way too much effort. I did find all sorts of ways to crash Quicktime and VLC though. Of course flickr's reencode ruined it too. | ericosur posted a video:

Now in HD :-)
1558 photos taken every 4 seconds (over 103 minutes) using the CHDK firmware for my Canon Powershot A620 and a timelapse script, encoded with mencoder with 24 frames per second.
Nothing special to see here, though! :-) |
