Grainy Low Light?

Hey all!
I love my K3 and I'm sure this is more something I've done to the settings or something than a lacking in its ability. I recently took up night photography but I'm having an issue with it. Even at iso 200 I am getting grainy shots with 30 second exposures. Is there a setting I'm missing that either needs to be off or on to overcome this? Here's a link to an example of what I'm talking about:

I just feel like there shouldn't be that much grain in the sky for how low of an ISO I used?

Thanks!

Did you have to pull up the low values in that shot to get to get its final look?

I can't see imgur at work, but I'm leaning towards user error here. The K-3 is quite clean at ISO 200 when exposed properly. If you have pushed the exposure up (or your RAW editor did it automatically for you), then you will see more noise.

I'd recommend to buy a full frame K-1, it'll be less grainy in low light.

You say that shot is 30 seconds at ISO 200. Is that image straight from the camera or a heavily processed file? What aperture did you use?

I'm asking because if you used a small aperture like f/11, even 30 seconds will underexpose. If you later brightened the exposure several stops in software you may have added.

The image looks B&W. Did you use a B&W filter that simulates film grain?

You have a double post you might want to delete. And why stop at a K-1 and not just recommend a 645Z? Both don't even come close to answering the OP's question. I've shot those kind of pictures at ISO 3200 and 6400 at 25-30 seconds so clearly the shot is probably under exposed and pulled up showing the noise.

Ok, at 30 seconds exposure, low iso nr could be switched on to suppress effect of dark currents that is independant from iso value.

Can't see your EXIF data, Sysdmg.

If you want meaningful comments from people, please put up an image with it intact, and without postprocessing.

There must be something going on that you are not mentioning. These are ISO 2500 and 3200 which is quite clean.

I second the Phase One or the Hasselblad H5D-200c

The Hasselblad H200C is a multi-shot back, which requires a laptop with the Phocus software running and an absolutely static scene in front of it order for Multi-shot mode it to work. In single shot mode its resolution is limited to 50Mp.

This camera would be inappropriate for the OP's purpose

Alright so what I've gathered from this thread.
A) I need to properly expose in camera rather than relying on RAW exposure manipulation. Check
B) I need a second mortgage. I'll work on it

Thanks all!
