First post in along time. What was the cause? This. I recently purchased this remote control for my camera which i highly recommend. It's cheap and has very neat features. Two downsides only : First, it is not wireless but i can i live with that. Second the minimum exposure time you can set for your camera from the remote is 1'. You can of course use the camera setting and override the setting on the remote but when you want to take different exposure steps and it's daylight you cannot adjust the shutter time to the ones you need without handling the camera (and thus moving it).
The main reason i bought it though was the time lapse capabilities. As a first test i shot a simple view of the sky.
The process you want to follow is easy. Determine first of all the time frame for your animation. You might for instance want to shoot 12 hours of a day from dusk till dawn. Once you figure out this time frame you calculate the amount of seconds it contains. For the example i gave you it's 12 hours * 60 minutes (per hour) * 60 seconds (per minute) = 43200 seconds.
After that you need to determine how long you want your video to last. Let's say you want your video clip to last 2 minutes. Again you figure out the seconds in that period. In this case 2 minutes * 60 seconds = 120 seconds.
Lastly you need to figure out the frame rate of your video. In the States that's usually 30fps while in Europe it's 25fps. Of course you can choose whatever you wish. You can have extra fast or even extra slow frame rates. Let's go with 25 for this example.
So our video will consist of 25 frames/second * 120 seconds = 3000 frames.
Now that we know how many frames we are going to shoot and the time frame for those we can calculate how often a new frame must be photographed. Thats 43200 seconds / 3000 frames = 14.4 seconds.
That means that we must set our remote to take a new picture every 14.4 seconds (unfortunately the model i bought only has a setting for integer values and so i would have to choose between 14 and 15 seconds which would yield similar results)
You then set your exposure and start taking pictures. Note that you have to set your camera to manual mode and adjust the settings correctly.
One last note about shooting time lapse at night. I tried shooting the stars . In the very dark conditions when i shot it, i realized that each frame had to be exposed for 30 seconds to get a bright enough result. So in this case the exposure time for each frame will dictate your other settings (such as how often you will shoot new frames and how long the animation will last).
The last step is to compile a video. You can use a lot of different programs (some free some not. Google and you'll find many) but for my very simple first attempts i used Picasa 3 which has a time lapse feature. The main reason i used that was that i had it installed, it is easy and i was bored to install another program. The only downside is the .wmv files it produces :D
These are my first results :

Hmmmmm....
- "Determine first of all the time frame for your animation."
- "Once you figure out this [...] you calculate the amount of seconds it contains."
- "After that you need to determine how long you want your video to last."
- "Lastly you need to figure out the frame rate of your video."
That sounds like an interesting web-utility...
It has been a while indeed. Reading I think i have a hint of an online course.That's a set of really clear and easy to follow tips. I just need the remote control to test.
P.S. Rethink the teaching job :P
