Brain Imaging Time-Lapse

January 28, 2011 Leave a comment

I’m taking advantage of a lull in online time-lapse news to feature something I normally wouldn’t post on this site.  The video above shows growth in a mouse’s brain in time-lapse.  To the best of my understanding, scientists put a tiny glass tube into a mouse’s brain.  Then they inserted some sort of imaging device and took images at multiple focal lengths.  The images were then “stacked” together to create one image.  “Stacking” is a common technique used for star photography and for macro photography as seen in this gigapan of a beetle.

Because the glass tube was left embedded in the brain, the scientists were able to image the same location several times and use the output of the stacked images to create a time-lapse video of cell and blood vessel development.  Of course, my knowledge of biology ends with dissecting frogs in 9th grade, so I’d suggest reading from these sources if you’re interested in learning more:

War of the Worlds

January 27, 2011 Leave a comment

Here’s an odd mash-up that works for some reason.  There doesn’t seem to be much of a connection between the HDR time-lapse on screen and Orson Welles’ famous War of the Worlds radio broadcast, but it’s still mesmerizing.

The scenery is breathtaking, the music fits well, and the photos aren’t overly processed.  The creator, Rafael Asquith, says he processed the HDR in Photomatix and then used Photoshop to convert to black and white.  He doesn’t mention the video software but my guess would be After Effects with some light grading.  Asquith says below the video that he’ll post his workflow soon.

Sydney Harbor New Year’s Eve

January 14, 2011 Leave a comment

I know I’m behind on posting this clip but I thought it was still worth sharing.  It was made by a team of people working on a professional contract and it shows.

If there’s one thing in particular I’d like to point out, it’s the quality of the fireworks capture.  I tried making a fireworks time-lapse once before and failed miserably.  To make this work, the artist had to set just the right exposure length and interval.  I’d guess he shot in continuous mode and used between 2.5 and 3 sec. exposures.  This would capture every firework and not make them too choppy.  The short exposure at night without noise means he used a very good camera.  I’d guess it was a mix of a Canon 5D Mk II and a couple of slightly less expensive cameras.

Mechanical Intervalometer

January 3, 2011 Leave a comment

I’ve featured a few different ways to take timed photos but this intervalometer build by Constructer is one of the most fun I’ve seen. I have to put this in the fun-but-not-very-functional catagory because I’m reasonably sure it causes some camera movement.

Constructer outlines the build on this Instructables page.  Even if this isn’t the most practical method of capturing photos, it does work with almost any digital camera.  So if nothing else works for you, why not give it a try?

December 20, 2010 Total Lunar Eclipse

December 10, 2010 1 comment

Image from NASA.  Click to enlarge.

When is it?

Beginning in the late evening of Dec. 20 or the early morning of Dec. 21, depending on your location, the moon will begin passing through the Earth’s shadow resulting in a total lunar eclipse.

Where Can I See it?

North America is the place to be for this eclipse as the entire display will be visible from all locations.  Partial views should be available from Western Europe to Asia and Oceania as the moon circles the earth.  The above map should let you know what to expect or you can visit the NASA website for more info.

Break Out Those Cameras

Another eclipse this good won’t be visible from North America for almost four years.  I’m planning on publishing some of the best time-lapse videos, so let me know if you have one you’d like to display on this site.  Good luck!

Homemade Time-Lapse Dolly

December 8, 2010 Leave a comment

Brian Grabski’s newest invention is a dolly designed to carry a camera over a curved track in order to make time-lapse videos. I was drooling when I first saw this machine and only grew more excited when I learned he had a write-up and video explaining the build. The bulk of the machine is made of wood.  It uses skateboard wheels on metal pipes and is driven by a servo motor connected to an electronic speed controller.

This might be much cheaper than buying professional equipment but I suspect Grabski had to spend some money putting this together. That large gear looks suspiciously like the new gearmotor gearbox sold through ServoCity for $59.99.  Throw in the precision digital speed control ($99.99) and manual driver ($49.99) and the project starts getting expensive.  Is it too late to put those things on my Chirstmas wish list?  More photos, another video, and some cool projects on Grabski’s website.

Interview with James Anelay of TimeLapseMe.com

December 1, 2010 Leave a comment

James Anelay recently contacted me about a new website he made that uses time-lapse images taken with a webcam to let users track their level of fitness. He agreed to do a Q&A for this blog.

How did you come up with the idea for your website?

When I started trying to get fit, I wanted to track my progress. Weighing myself tells me what I lost, but it’s not very interesting. I wanted an interesting way to track my progress that maybe I could share and inspire people to do the same.

I’ve been going for two months and only lost about 7lbs because I was trying to gain muscle at the same time. A time-lapse video shows my progress even if a scale doesn’t.

How do you align the images to make a seamless transition?

To align the images, we use the first image the user has taken as a background to a second webcam image (opacity is adjustable). The user can then simply set the timer and align their body with the previous image. It’s then automatically uploaded to the server and stored in the user’s folder.
To turn the images into a video, the user will enter a title, subtitle, and their name. A fading effect is made by using Imagemagick, some software on our server, which creates a fading effect.

We then combine those images into an flv video using ffmpeg, some more software on my server, which simply puts them into the video in order of image_1 to image_200 as well as adding music the user has uploaded.

Are users able to share their videos?

At the moment we have limited users; eventually I will be making it so you can share your video, make journals, and be a lot more social. We only started two months ago so the users’ videos are very short at the moment. However, an example of a similar video is on the homepage.
