Hi,

here is some of the tests I did tonight with 16 second exposures:

this is a ling to my gallery since I have no idea how to insert pictures.

All the other pictures in my gallery are long exposure tests...

 

There's a lot of JPEG noise in these pics. That isn't a criticism, mind you, I experience the same thing all the time. I too have a Kodak Digital camera, A DX7590, also allows me to do up to 16 second exposures. But for that long of an exposure, I really have to experiment more, because it always seems to let way too much light in, overexposing my images. I've only tried it at night, no daytime shots.

Let us know if you figure out how to get cleaner photos!

 

I'm no photo expert, but I beleive the "grainyness" is casued my an ISO 400 equiv. being exposed for so long. If you try 100 or even 200 it should not be as bad.

Anyone is more then welcome to correct me as I could be completly wrong.

 

With any point & shoot, I'd keep it set to ISO 100, and keep "auto ISO" off.
200 if you're pushing it, but I'd keep away from 400 on up with most p&s.

Plus, if you're using a long exposure, there's really no need for a high ISO.
A high ISO is ideally used to maximize shutter speed.

If you're shooting for a shallow depth of view, then just open up that aperture, and this will help gain even more shutter speed.
If you're shooting a landscape type shot, then you'll probably want to stop down the aperture, and use a longer exposure.

Hope this helps

 

Regarding ISO 400 and the 16 second exposure:

If you used ISO 100, your equivalent exposure time would have been 1 minute. A lot of P&S's don't have bulb mode and they don't have pre-set time incriments greater than 30 seconds. So, I can see why you may have used ISO 400 to get the shot given the issues with the camera, but (lacking bulb mode) ISO 200 for 30 seconds would probably have been the better choice in terms of noise.

 

Not to Hijack this thread, but I just took a peek at your site DiD...

You have some absolutely beautiful shots in there
Some of them look like Medium Format... very nice.

 

Thanks for the advice everyone. I know a P&S is not the ideal for this, that is why I intend buying Digital SLR in the near future.

 

Thanks for the comments, especially that last one. 95+% of those images were shot with a D-SLR, and a small handful were done with a 4 MP P&S.
