Over in our forum one of our members Chrismar (visit him on Flickr here) put together a great tutorial on how he created a time lapse photo video using his Canon Digital Rebel XT dSLR and TI-83 calculator as his intervalometer.
Here’s his video (there’s another one at the bottom of the post) with his tutorial following:
1) Set-up your shot. Use a tripod or sturdy location to place your camera. I put mine in front of the TV in the entertainment center.
2) Take a test shot. Take a test shot of the area to calculate your exposure and to set the focus. I knew I wanted about a 2 second exposure, so I took my test shot in Shutter Priority mode.
3) Adjust the camera settings. Switch the camera into manual mode. Use your test shots exposure information to set the aperture. Set the shutter speed to what you used in step 2. Turn off auto white balance. Set it to a preset or custom. Basically make sure any auto features are not on auto, otherwise you’ll get a nasty flickering (like I did).
4) Take another test shot. Only do this if you have easy access to the viewfinder, and use a remote to avoid camera shake. This shot is just to make sure the images are properly exposed using the manual settings.
5) Setup your intervalometer. I used a TI-83 calculator as my intervalometer. See the links below for the instructable. I set mine to fire in 10,000 TI-83 cycles, which worked out to be around every 26 seconds.
6) Hook em up together. Hook up your calculator (or intervalometer) to your camera and press start.
7) Wait. For me, waiting wasn’t that bad since I was playing Mario Kart. But doing a nature time lapse will require a significant time commitment. For my example the time was just about 3 hours.
8) Compile the video. After the sequence is done and you’ve downloaded your images its time to make the video. I used QuickTime Pro as it was the easiest method and gave me the best results. I tried a few free applications, which worked, but I liked the flexibility QT Pro gave me. In QT Pro simply go to “File -> Open Image Sequence…” and then chose the first picture. Be sure to set your Frame Rate at something between 10 and 30. I used 15 for mine. If your files are numbered sequentially QT will be able to figure out which pictures to add. From there you can “File -> Save As…” a QuickTime .MOV or you can “File -> Export” to a number of different formats. If your video is long enough you can add music and the like. See the links for some sites to get free creative commons licensed music.
9) Post your video. I put mine on Flickr, but you can put yours on YouTube or any other video sharing site.
The shots for this time lapse were taken with my 18-55mm kit lens at 18mm, f/8.0, 2 second shutter speed and 26 seconds between shots. I accidentally left on auto white balance, which is what gives it that flicker.
As promised – here’s another of the Time Lapse videos from Chrismar.
