well, the combination of the long shutter speed and a higher ISO are both going to work against you when it comes to grain / noise. Does your camera have a "long exposure compensation" function that you can set? I have one on my Nikon D70 and I usually turn that on when I'm taking night shots. I always try to get away with the lowest ISO possible, regardless if I'm shooting at night or not.
are you using a high ISO to compensate for not having a tripod? Also, have you thought about some noise reduction software like NeatImage or Noise Ninja?
I can offer some suggestions once I know a little bit more about what you are using when you are taking night shots.

I have similar problems and don't think there are 'standard' settings. I try to keep the ISO down and bracketing the exposure might help. It might be a good idea to go out and take lots of shots at different settings then see what works best for you when your home in the warm in front of the pc. You can then go out on your shoot with a more educated guestimate of the settings (btw, I'd also suggest going manual)

| On the 20D which is very very good at night shots I don't mess around with the ISO if it's a landscape of a long exposure type shot. Set the AV to somewhere around f/20 - f/24 and a good tripod. You will let it burn anywhere from 3-5 sec up to 30 seconds. With the 20D 30 sec will almost turn a night shot light. If the ISO is left at 100 the grain won't be too bad. In fact I have several that needed nothing to remove the grain, one won 2nd place in 2005 Texas State Fair of the San Antoni Riverwalk taken like that. In fact it was using the 18-55 kit lens and worked great. If you start adjusting all the different parameters you will not know what to adjust next time to get it right. Either adjust the ISO, the Av or time, then make corrections from that point. In the end you may find the right combination that works for you. Oh maybe try manual focus on night shots. Sometimes the focus will wonder on real long exposures. |
