I have a canon powershot s2 is and I am wondering two things:

1) How can I take a longer exposure than the maximum of 15 seconds?

and

2) How do you pan? I have a tripod, and I want to know how.

Thanks! :)

1. No idea

2. You need a 3D tripod head that can adjust in three different planes. Then you need to set the tripod head and legs so that when you pan the head around 360 degrees it follows the real horizon (or a stand-in one) and maintains the same level throughout its arc. This is actually very tricky to do in many cases. It will start and end in the same place but often not follow the horizon in its arc. I use a little bubble level that measures level in two directions and place it on my tripod's head to help get me in the ballpark but then usually still have to tweak things.

Thanks Doug F, hopefully someone who help me with the longer than 15 seconds exposure time.

For the Pro1 and most if not all the G series cameras, 15 seconds is the absolute maximum.
I think it is the same for the S2 IS, excluding a hacked firmware, I know nothing about it.

If you tell us what do you need more than 15 seconds for, perhaps somebody knows how to do that within the 15 seconds limit.

Regarding panoramics, although finding the camera nodal point, using a pano-head and carefully leveled tripods is a must for precision work, the casual photographer can get rewarding results on panoramics shot even hand held. A normal tripod will help a lot, of course.

Setting your camera to stitch assist mode (page 49 and pages 52-55 of the user guide) and shooting a 3 or 4 images horizontal panoramic to be stitched with ZoomBrowser’s Edit > Stitch Photos tool will give you fast hands-on experience on this technique.

Avoid objects near the camera in your first attempts.

Late night photography, that's why I'd like to know if I can hack my camera or do something so that my exposure is longer than 15 seconds. :)

Thanks for the tips on panoramic as well,
that's something I'll do sometime when I have the chance.

You can do multiple 15 sec exposure then stack the images.Search the internet for "image stacking". The only thing is you will need to wire some sort of external remote unless you are planning to stand there and press the shutter every 15 sec manually.

Just a quick comment on "nodal point". You only really need to worry about if you have very close foreground objects. For panoramas of landscapes without foreground objects you can just do with a tripod and better stitching software like PTAsmblr which have a number of automatic tools to correct for camera rotation and panning.

For long exposures, I have used the 15sec exposures stacked with the program
Registax V4
from
http://www.astronomie.​be/registax/ (external link)
This program is FREE, not a trial
Take a series of exposures, kick out the bum ones, and let the program stack as many as you wish -- it will do one point and multiple point alignment
