Doing a timelapse...what do you set your intervals at?

I just got my intervalometer for my t2i and I am really excited. What would everyone suggest for an interval time?

1 second, 3 seconds, etc?

I am going to try and do a dramatic cloud time lapse, a busy street one, possibly a sunset, etc. I'm pretty set on all of the exposure stuff, I am just wondering what everyone sets their intervals to.

Thanks for the help!
 
2 seconds.

exposure is based on what look your going for.
if its traffic or people. 2- 4 second shutter speed.
astrophoto -anything from 15-30 second shutter speed.
 
Speed,

"If its traffic or poeple" you mean 2 second intervals, or a 2 second long shutter opening?
 
Sorry..

Intervelometer is set to 2 seconds.
shutter speed is depending on Scenario.
Traffic and People 2 - 4 seconds depending on how much of a FLASH trail you want .

here is an Example of a Car time lapse I did from Inside the Truck

I used a 2 second delay shutter speed and a 2 second delay on the intervelometer. so Essentialy a Picture every two seconds with an exposure of 2 seconds each.

Whala!

What do you recommend for shooting stars?

I shot one with a 15" exposure every 30" but the stars moved way too fast...or maybe it only looked that way because I was using a 50mm on a crop sensor? I shot one with a Tokina 11-16 that was 10" exposures every 3" and it came out too slow...do you think this is because I'm not using the proper speed setting for the type of lens I'm using? I've only shot 2, so I'm pretty new at this...

and if I'm correct, it takes 6 hours for the stars to make a quarter rotation?

360º = 24 hours

360º/90º = 24/4 = 6 hours

I recently shot 10 second exposures with a 5 second interval between exposures. I think I was on ISO 1000. It came out lovely.

How is it that people are shooting with longer exposures than intervals? Shouldn't your interval have to be at a minimum what your exposure is set to?
 
Your thinking about it slightly wrong.

A ten second shutter time and a 5 second interval is doable. It is not that ever 5 seconds you take a photo while your still on a ten second shutter. It is that you take a photo for ten seconds then five seconds later you take another. Then after the ten seconds shutter five seconds later you take another :) make sense?

The only thing I can suggest on your math is your taking the whole sky and the time for the whole earthy to rotate back to that one star. While that could be true I think for practical purposes its not like that. We do not see the whole sky we see a small sliver of it based on your location and time of year as well as the time of day. So while it mike take 24 hours to do a full circle you might only see those starts for say 5 hours of a night so really you want to know how long and how fast they move across the sky during that five hour window?

looks great! That is the speed I was looking for.

Well, I have no intention of doing a time lapse of stars for 24 hours (is that even possible?) since we only see the dark sky for a portion of our rotation. I was using this math to simply chart the movement of the stars within that small "sliver" while they are visible. I tested it out on my latest, and I was correct! The stars moved to the exact position I calculated...

How would you set your intervolameter though?

What kind of intervelometer are you using?
