I ended up picking this Nikon camera. It is not a dslr, and there's not an option for changeable lenses, though the zoom is great on it. I felt like this was a good choice for learning manual settings and having a camera that didn't feel SO huge to carry around with me when we go out. Plus, we got it from Costco, so I have a couple of months to play around with it and can return it if it turns out to really not be what I want. But really, I think I'll be fine.
I mostly want to take better blog pictures and better pictures of the kids. I'm not doing crazy telephoto stuff or extreme sports and action shots.
I've been reading things online to learn about aperture, ISO and shutter speed, as well as checking out the manual on CD that came with the camera.
And look--here's one of my practice shots--unedited even!
