Bristol Mini Maker Faire Timelapse

Posted by barnoid Tue, 26 Mar 2013 11:36:58 GMT

One shot about every 10 seconds between 9:30 and 4:30ish covering the whole of the first Bristol Mini Maker Faire.

The camera rig can be seen clamped to the furthest pillar in my previous photo.

Unfortunately Flickr applies heavy compression to videos which looks bad on videos with a lot of movement like this. It looks slightly better on Vimeo.

Wedding Reception Timelapse

Our wedding reception in 49 seconds. I didn’t have much time to set the camera up so it dropped to 30 second exposures when the sun went down. The strange moving clouds of light are people dancing. See if you can guess at what point the fire alarm went off.

A timelapse of the setup followed by the whole of the event and then the tear down. The sun shining through the window made the exposure less than ideal for most of it.

Cress

Posted by barnoid Sun, 22 Apr 2012 22:14:00 GMT

Here is the final version, see also the test run and the making of.

Briefly: 2125 shots taken every 2 minutes over 70.8 hours with a Canon EOS 40D with a Canon 50mm f1.8 lens with a +3 close-up filter wedged in the end. Cress seed on a bunch of damp cotton wool on a saucer on my home/hackspace made stepper motor turntable (3000 steps per revolution). In a cardboard box lined with a cut up white sheet, lit by a 20W daylight compact fluorescent light. The turntable and camera were controlled by an Arduino which turns the table one step just before taking the photo. The camera was set to manual, 1/8th second, f10, ISO 100.

The test shoot was fairly flickery due to the lens not being totally accurate when it stops down the aperture to take the shot, so this time I pressed the aperture preview button and turned the lens slightly to disconnect the electrical contacts. This keeps the aperture stopped down and the camera unable to do anything about it, resulting in a consistent exposure every time.

Despite claiming "daylight" the CFL is actually considerably cooler (see the test shoot). For this version I’ve corrected the white balance by batch processing with imagemagick. I also did the fade with imagemagick and then made the movie with ffmpeg.

There’s a bit of a glitch around the one minute mark, this is where I watered the cress which caused the cotton wool to expand making it look like the whole lot jumps upwards slightly.

Cress in Progress
For the next five days this is happening in the cupboard. Cress really moves fast, the seeds started swelling as soon as I put them on the cotton wool.

Test Cress

Posted by barnoid Sun, 15 Apr 2012 12:43:23 GMT

This is a test for a longer time-lapse I plan to make of cress germinating and growing. It consists of 902 photos taken every minute over 15 hours. It’s shot in a cupboard in a cardboard box lined with a white sheet and lit with a 20W daylight-coloured compact florescent light. I used a Canon EOS 40D with a Canon 50mm f1.8 lens with a +3 close-up filter which doesn’t fit the lens thread but does fit when kind of jammed in the front. This allows it to focus to about 8cm, but with very little depth of field (the aperture was on f8). I made the photos into a movie with ffmpeg.
