Thanks everyone! This is a great community...
I recently bought a K-x with the thought of grain in mind, but, it does a great job with low noise images too... Wonderful when shooting colour...
I guess I will have to go the post processing route, but, I am stubborn and like to get my images to look like I want them to look right out of the camera. Film would, of course, solve this problem and I do have a lovely range of film cameras, but, here in Sweden, it costs a LOT to get prints done & I don't have any good place to set up a darkroom, nor do I have any equipment any longer.
Perhaps I will try
Lowell Goudge's suggestion and shoot some jpgs using the filters a little. Normally I shoot RAW, but I will give RAW+ a go for a while I think.
Thanks again everyone... I seem to have started a thread expressing concern about how tough it is to get noise out of the K-5 (the reviewers would go nuts) :-)
