Timelapse with the Canon TC-80N3
 

Does anyone know of any good sites that detail which settings to use (both on the 7d and the intervalometer) to best achieve different looks (i.e. clouds passing during the day, capturing the movement of the stars, a city at night, a scene where the light dramatically changes from day to night etc etc)? There seem to be plenty of videos online but very few that set out what settings they used to achieve that particular look

Check Philip Bloom's blog, he has several posts (and examples) of time-lapse, though this post is a good place to start: DSLR Timelapses addictive, frustrating and often rewarding… | Philip Bloom

I'd also check out: Timescapes - Digital Timelapse Discussion Index page

Tim,

The above link to the Timeccapes forum will help you. Lots of good info there.

Here's some detail and an example of a quick one I did last week :

Canon 5D Mark II
Canon 24-70mm 2.8 lens with polarizing filter
Manual setting locked to1/20 sec @ f16
100 ISO
Lens twisted off contacts to prevent aperture caused flicker
Intervalometer set for one frame per second

Processed in Adobe Lightroom, Quicktime Pro, Final Cut Pro

Tim, You want us to give away our special sauce. Different shots require different settings to get the desired results. It depends on how long you want the shot to last. Also the motion you want to capture can be manipulated in post so you can shoot at one frame rate but speed up or slow down at another. Do you want the clouds to be sharp then use a faster shutter speed. Do you want them to move fast then use a longer interval between shots say 5 or 10 seconds or longer. Day to night is tricky as you might want to discretely change shutter speed at certain points to get a better exposure. Not sure the 7d can be ramped easily but you will have to play around to see how your rig works. You can also smooth out big changes with After Effects and Final Cut. Take a look at my stuff on vimeo done with still cameras and an HPx-500
