Hi All,

I'm still exploring my new Canon Digital Rebel and something has been concerning me.

I've wanted to do some nice waterfall photography and the consensus seems to be that just after sunrise, just before sunset or on a day that's overcast is better, especially with long exposures.

So off I went hiking today to a local nature preserve, hiked down to the bottom of a waterfall, got the tripod setup and started shooting.

I was mostly experimenting and tried exposures from 1 second to 30 seconds (with the smallest apature, I think it was f/22). I did this at ISO 100.

Now, most of the shots came out "good" (but not great). Mostly composition, some blown highlights, etc. But one thing I noticed was noise! Lots of it!

Well, ok, I'm not sure if it's "alot" or not, but it was very noticable. Running it through Noise Ninja clears alot of it up.

I guess my question is... Is this normal? It was about a half hour before sunset, partly cloudy with some tree cover, iso 100, with exposures between 1 and 30 seconds.

I guess one thing that concerns me is that I want to do some night photography. Does this mean I'm going to get alot of noise regardless?

Thanks.
