Ah right, I wasn't too sure but glad to have that cleared up. Still don't understand how that's possible, i guess the camera keeps taking 'pictures' internally and overlaps them all until it creates the final shot?
I'm not good on the technical side but I might be able to dumb it down enough to where
I can understand it 
It's not that that camera keeps taking picture, it's only one. If you have your camera set to shutter priority for 10 seconds, that shutter opens once and stays open for exactly 10 seconds letting light in the whole time. Picture one of the old like this one....
The photographer would put a special plate in the back which would act like film. He took the lens cap off which would let light in and burn an image onto that plate. The darker it was outside, the longer he needed to keep the cap off to let the light burn in more. The downside was that if he were trying to photograph a person, they needed to stay PERFECTLY still the whole time, or the picture was blurry so the photographer wanted to use hoot outside on a bright day because he wouldn't need to leave the cap off very long which reduced the chance of the person moving because it was only a second or so.
Now skip ahead to present day. When he took the cap off, that is exactly what your shutter does. It lets light in to be captured by your cameras sensor(acting like the plate in the back.) For a 10 second shot, it's usually letting light in at a slow rate for both what you are trying to capture, and also that guy who doesn't see you with the tripod set up and walks right past.
When someone walks by they might appear as a ghost in the picture or if they weren't in the frame long enough, the light from your background will eventually overwrite it.
I haven't used photoshop for a long time but I can understand what you mean by that. Is that also the case for those fireworks shots? I dont know how people get those so perfectly, they obviously use a shutter release but what else? Is it long exposure or shutter speed priority?
Sometimes yes sometimes no. There are a good amount of guys and gals over there that have tricks to do everything in camera like filters for example. Strap on a 4 stop filter, and now you can take a picture with a 10 second exposure and it won't be too bright even with fireworks. It's crazy

I know that's oversimplifying it, but I'm just making a point that it is possible, and yes, a lot of them are THAT good.
I've done fireworks merges in photoshop before and made a 1/2 decent picture look pretty darn good in about 30 seconds or so.
Don't worry about updating, I know what you mean, Stef is pretty much the same 
It will be soon. I want to get this thing over with before our next trip. We've been planning one with Tina's mom's family in October, but we've decided we can't wait that long......so......

Looks like a May trip is in order!
