Long exposure tips needed

Any tips on taking long exposures, please!

I'm having a lot of fun testing the limits of the G1, and took a photo of the Aurora a few nights ago. At f2 and 8 secs it was still underexposed but I couldn't do more without taking the lens right out

Check out the results at http://www.netidea.com​/~teekay/temp/aurora.h​tm

I did manage to get this usable but very noisy image by boosting the brightness in PSP, but thought afterwards that it might have been better to use ISO 400 in the first place.

Anyone done any tests to see which produces less noise: ISO 400 or post-brightening from ISO 50?

And is there any way to get longer exposures than 8 seconds? Taking two then combining somehow?

Hi

my experiences with even ISO 400 (or even 200 for that matter) is generally quite bad......the noise is terrible!

By the way, wat is the techique you use to brighten in PSP?

Red Dawn

The normal COLORS - ADJUST - BRIGHTNESS/CONTRASt menus. Shortcut is SHIFT-M
