Damn I need to play with the settings more. I'm not in love with the grainyness of the first pic. Any suggestions?

Settings:
ISO: 50
Shutter spd: 8 sec
Fstop: 2.8
4.0 megapixels
1600 resolution (superfine)

I have no idea on the settings, but damn I like your A4....

Try using a real camera in stead of a digital. If you choose the right fill there shouldn't be any graininess. Also you might be blowing the image up to much.

you are gonna get some graininess no matter what kind of camera you shoot with (film or digi). If your film speed goes anywhere over 400iso, you are gonna get grain. The same goes for digi cameras, if the camera's iso speed is set to 400'ish+, it's gonna produce grain. That's just the way it goes when you shoot night photos w/ fast film speeds.

The only real way around this is to make sure your digi is set to 100iso (or shoot 100iso film) and shoot long exposures. It looks like you are using a tripod, so you shouldn't have any problem doing 30sec - 2min exposures.

that second pic looks real nice, you should make that into a wallpaper for us (hint,hint).

Faster film will reduce the grain....get ASA1000. Damn, is that the luxor? Second shot looks like Newport....

It's actaully the Pyramid at CSULB, my Alma Mater. And the 2nd pic is in Belmont Shores/Seal Beach. Right off PCH.

I was at 50 ISO. Is that as good as it gets? Also my exposure was at 8 seconds. I think the longest I can set it to is 15 seconds, but then it looks blown out. Should I close the aperature at that point?

not to get in a pissing match here, but unless you meant ASA100 not 1000, the faster the film, the grainier you get. That's why photographers who shoot studio strobes (like me) can shoot 50ASA (ISO) film and get the least amount of grain and the sharpest results possible. The only benefit to shooting fast film, ie: 400+ is to gain more latitude with your exposure. The faster the film, the more shutter speed or aperture you have. Sports photographers shoot fast film like 1000iso only because they need as much shutter speed as possible to capture the action under poor lighting conditions. Do a search, you'll see.

and to answer your question JMG... that's the best you can do. 50 iso is a very good number for what you were trying to do. Unfortunately, digi cams just haven't come far enough in the consumer market to really capture great long exposures. What you are seeing isn't so much "grain" since there really is no grain in the digital world (grain refers to the make-up of physical film), you are seeing "noise", mostly purple noise most likely. Most any consumer camera under $1500 will do just OK when it comes to long exposures. Even some of the pro cameras such at long exposures.

And yes, the longer the exposure, the more you need to close your aperture (or "stop down"), which means you need to have a bigger f-stop number. If you shot 8 seconds at f/4, and you wanted to shoot 15 seconds, you would need to stop down to f/8'ish

here's what I did in a few minutes... color is still off, but closer.

I went back to my originals and just tweaked the color a little. Looks better now.
